TeeChart VCL version 7
Chart Axes
* Alternate labels.
Axis labels can now be displayed in "alternate" mode to show more text in the same space.
Suitable for horizontal axis and non-rotated labels.
Chart1.Axes.Bottom.LabelsAlternate := True ;
Bar, Bar3D and Horizontal Bar series
* Tick lines.
New TChartPen property to draw lines around Bar series points at default axis grid positions.
Series1.TickLines.Visible := True ;
TChartListBox
* Radio buttons
The listbox control can now display series with "radio" buttons instead of check-boxes.
This can be useful in cases where only a single series needs to be visible.
ChartListBox1.CheckStyle := cbsRadio; // ( default is cbsCheck )
* OnChangeActive event
This event is called when the end user clicks the checkbox or radio icon to show or hide a Series. The event includes the Series.
Chart Themes
"Themes" provide an easy single-click way to alter many of the Chart formatting and color properties.
Included themes are TeeChart, Microsoft Excel®, Business, Classic and Web.
End users can change the selected "theme" at runtime either using the chart editor dialog new Themes tab or the Themes editor stand-alone.
Uses TeeThemeEditor
ChartThemeSelector( Chart1 );
Themes can also be selected programatically.
Uses TeeThemes;
ApplyChartTheme( TExcelTheme, Chart1 );
New custom themes can be created and used at design-time with simple code:
TMyTheme = class( TChartTheme )
public
procedure ApplyTo( Chart: TCustomChart ); override;
class function Description:String; override;
end;
RegisterChartThemes([ TMyTheme ]);
TColorBand tool
* New OnClick event, and Clicked and BoundsRect functions.
The color band object now provides an OnClick event, Clicked function and BoundsRect function that returns the color band rectangle in pixels.
TCommander
* Editor and Previewer
The commander control adds two new properties to show customized chart editor and print preview dialogs, using your preferred TChartEditor and TChartPreviewer components:
TeeCommander1.ChartEditor := ChartEditor1 ;
TeeCommander1.Previewer := ChartPreviewer1 ;
Custom Chart Color Palettes
The default color palette is now a dynamic array that can be replaced by code:
// Create a custom color palette
var MyPalette : TColorArray;
SetLength(MyPalette, 5);
MyPalette[0]:= clBlue;
MyPalette[1]:= clGreen;
MyPalette[2]:= clLime;
MyPalette[3]:= clAqua;
MyPalette[4]:= clNavy;
SetDefaultColorPalette( MyPalette ); // set new custom palette
MyPalette:= nil; // free if no longer used
Several predefined palettes are available at runtime:
ColorPalettes.ApplyPalette(Chart1, 3); // 3 = pastels
Delphi for .NET
New in this version is support for Borland Delphi™ 2005 .Net compiler.
Under Delphi.Net, applications can be created to use the Borland VCL for .Net ( VCLForms ) or to use Microsoft FCL for .Net ( WinForms ), or ASP.Net web server pages.
TeeChart v7 VCL is designed to be used in VCLForms (Win32 or .Net) but can also work in WinForms and ASP.Net forms if you create the necessary encapsulating classes.
For easier programming in WinForms and Asp.Net, we provide TeeChart.Net (written 100% in C#) which uses .Net Framework classes directly bypassing the VCL. As with the VCL version, this version can also be used in VCLForms applications through new a new .Net Control Import Library Wizard.
Design Time options
New editor dialog to control all design-time options.
Selections are stored at Windows Registry under key:
HKEY_CURRENT_USER\Software\Steema Software\TeeChart Pro
The design-time options editor can also be displayed at runtime in your applications:
uses TeeDesignOptions;
with TOptionsForm.Create( Self ) do
try
ShowModal;
finally
Free;
end;
Chart Legend
* Radio groups
Legend can now display "radio" buttons alongside series to let the user choose a single visible series.
Chart1.Legend.CheckBoxes := True; // activate boxes
Chart1.Legend.CheckBoxesStyle := cbsRadio; // ...or cbsCheck
* Scrollbar tool
New tool to add scrollbar facilities to Chart Legend.
The scrollbar is not derived from Windows or Borland's VCL scrollbar objects. It's been totally rewritten in Delphi with full source code available.
The scrollbar editor dialog provides many formatting properties like colors, sizes, etc.
Uses TeeLegendScrollBar;
MyScroll:= TLegendScrollBar.Create( Self );
MyScroll.Size:= 12;
Chart1.Tools.Add( MyScroll );
* Legend Title
The Chart Legend provides a new property "Title" of class TTeeShape.
Legend Title text and formatting can be fully customized.
with Chart1.Legend.Title do
begin
Text.Clear;
Text.Add( 'Animals' );
Color:= clMaroon;
Transparent:= False;
Transparency:= 50;
end;
* Miscellaneous
New LastValue (Integer) read-only public property.
Returns the value index of the last visible item in legend.
This complements the already existing FirstValue property.
New 2D Lighting Tool
The new TLightTool class enables "2D lighting" effect to charts.
Several properties can be customized using the Light tool editor dialog.
uses TeeLighting;
var Light : TLightTool;
Light:= TLightTool.Create( Self );
Light.FollowMouse:= True;
Light.Style:= lsSpotLight;
Chart1.Tools.Add( Light );
New Functions
* Mode
The Mode function calculates the value with highest count of duplicates inside the source series data.
Includes the option to ignore null source values.
* Median
Calculates the value located in the middle of sorted source series values.
* Correlation
Calculates the factor, from 0 to 1, of X to Y relationship of source series values.
* Variance
Calculates the average spread of source series values.
Chart Editor
* Tree mode
The Chart Editor dialog can now be displayed in "tree mode", using a left-aligned treeview control as the main manager of the many editor dialogs.
The above design-time options dialog controls the default editor mode (normal or tree).
The ChartEditorPanel control can also be displayed in tree-mode.
You can also programatically force the tree mode display:
TChartEditForm.SaveOption( TeeMsg_TreeMode, True );
ChartEditor1.Execute;
Pie and Donut series
* Gradient 3D property
Pie and Donut slices can now be filled in 3D mode, using a Gradient property.
Series1.Gradient.Visible:= True;
Point3D series
* Lines to floor
New TChartPen property to optionally draw lines from 3D xyz points to chart floor.
Series1.BaseLine.Visible:= True;
Chart Canvas
* Full 360 degree rotation in GDI mode
Last released version 6 provided 180 degree rotation in normal Windows GDI mode.
Version 7 now delivers full 360 degree rotation, thus allowing viewing charts from back perspective.
Chart1.View3DOptions.Rotation := 220 ; // back view
* Vector fonts (pending)
Chart Series Groups
Series can now be "grouped" in logical sets.
Any Series can be assigned to pertain to zero, one or more groups.
Series Groups are optionally displayed at Chart Editor dialog and ChartListBox control.
var g1,g2:TSeriesGroup;
g1:=Chart1.SeriesList.AddGroup('First group');
g1.Series.Add(Series2);
g1.Series.Add(Series4);
g1.Series.Add(Series6);
g2:=Chart1.SeriesList.AddGroup('Second group');
g2.Series.Add(Series1);
g2.Series.Add(Series3);
g2.Series.Add(Series5);
ChartListBox1.SeriesGroup:=g1;
ChartEditor1.Options:= ChartEditor1.Options+[ceGroups];
ChartEditor1.Execute;
Chart Gallery
* Smoothing ( Based on "Resample" code from Anders Melander and others )
New Chart Gallery option displays charts with "smoothing" effect.
ChartGalleryPanel1.Smooth:= True ;
Compare the two pictures below. The left one is showing a smooth gallery.
You can also use a global method to smooth your custom bitmap images.
uses TeCanvas;
var B : TBitmap;
begin
B:=TBitmap.Create;
try
B.Width:=Image1.Picture.Bitmap.Width div 2;
B.Height:=Image1.Picture.Bitmap.Height div 2;
SmoothStrecth(Image1.Picture.Bitmap, B);
Image2.Picture.Assign(B);
finally
B.Free;
end;
end;
* Miscellaneous
New methods to get from and save to registry the gallery Smooth mode:
DefaultSmooth and SaveSmooth.
Exporting Formats
* SVG (Scalable Vector Graphics)
New exporting format available to export charts to SVG format.
Note: For the link below to display properly you'll need to install in your machine either the free Adobe SVG Viewer, Corel's viewer, JASC WebDraw or use Microsoft Internet Explorer.
* Click to open TeeChart_Example.svg file.
* View example SVG source.
* Go to SVG homepage
* PDF improvements
The TPDFCanvas object now provides several enhancements to PDF exporting.
A partnership with DynamicPDF company offers server PDF charting and more.
* GIF and LZW compression Unisys patent.
According to Unisys at http://www.unisys.com/about__unisys/lzw , patent on LZW compression has expired worldwide except in some particular countries.
Check the above link to verify your license rights to use LZW compression in your location.
The TeeChart version 7 now permits usage of LZW ( TeeGIF unit and editor dialog ).
All Series with "Pointer" property
The TSeriesPointer class now includes a Transparency property.
Many series styles like Line, Area, Point, Point3D, Polar, Bubble, Gantt, Bezier, etc have a Pointer property.
Series1.Pointer.Transparency := 50 ;
Candle and Arrow series, although providing a Pointer property, do not support Transparency as they draw points using their own method.
All Series
New MandatoryAxis function that returns the chart axis associated with the series (vertical axis in series mandatory value list is Y, and horizontal axis in mandatory value list is X ).
Series1.MandatoryAxis.LabelsFont.Color := clRed ;
Chart SeriesList property
New ClearValues method to remove all values from all series in chart, thus leaving all series empty.
Chart1.SeriesList.ClearValues ;
TSmoothingFunction and TBSpline class
Removed limitation on number of source points to calculate smooth points.
(Fixed size arrays have been converted to dynamic arrays).
Warning: Smoothing more than 500 points can be a very slow operation.
New Series styles
* Bubble3D, derived from TPoint3D series.
New bubble series that adds a "Z" value for each bubble point.
Requires OpenGL rendering to correctly visualize solid 3D bubbles.
Fixed bugs
* TBollingerFunction
Calling Clear on series with Bollinger now clears the two Bollinger line series instead of just one line.
* Canvas Custom drawing
Custom drawing could sometimes display text with shadows or outlines.
* Zoom pen
The Chart1.Zoom.Pen.SmallDots property did not work.
* Canvas EllipseWithZ and Pie3D methods
Improved distortion on big (ie: printed) Pie and Ellipse drawings.
* TCustom3DPaletteSeries
Fixed loosing the PaletteStyle property when cloning series.
* Tower series
Added Assign method to support cloning.
* Series1.DataSources
This property is now of type "TDataSourcesList" class.
Calling the Add, Delete and Clear methods will call the internal series methods. This avoids an access violation when closing or destroying.
* Legend
When the legend is behind the chart (using Legend HorizMargin or VertMargin properties), Chart1.OnClickSeries was not working correctly.
TeeTree2
* Teetree2 is now avialable for those who hold a current TeeChart Pro v7 license. This tree building component is a worthy addition for any developer working with Delphi. Follow the link to find out more about what TeeTree2 has to offer.
TeeChart VCL version 6
Chart Axes
* Labels can be fully customized using Items[ ] array property.
This makes easier to customize axis labels without using events like OnGetAxisLabel, etc.
Also, each label item is a full object with properties like Color, Font, etc.
Chart1.Axes.Left.Items.Clear;
Chart1.Axes.Left.Items.Add( 123, 'Hello' );
* Axes can be positioned along the Z (depth) direction when showing in 3D mode:
Chart1.Axes.Left.ZPosition := 100;
* Axes can have Offsets (in pixels) for both Minimum and Maximum scales:
Chart1.Axes.Left.MaximumOffset := 4 ;
Chart1.Axes.Left.MinimumOffset := 4 ;
* Axis labels are now individual objects derived from TeeShape object.
By default they are set to transparent, and can be configured to display a filled background, shadow, gradient, etc.
Chart1.Axes.Left.LabelsFormat.Color := clYellow ;
* Axis in Logarithmic mode now accept floating point values for Logarithmic base.
This allows, for example, setting a logarithmic axis of base "e" ( e = Exp(1) = 2.71...)
Chart1.Axes.Left.Logarithmic := True ;
Chart1.Axes.Left.LogarithmicBase := Exp(1) ; // 2.71...
* New PositionUnits property to specify PositionPercent as percentage or pixels.
Canvas
* Charts can be rotated 180 degrees along the horizontal (x) axis.
In previous versions, canvas was allowed to rotate 90 degrees only.
Using OpenGL charts can be fully rotated 360 degree.
Example to show how to "auto-hide" left and right walls while rotating the chart.
* The center position of Radial gradients can be customized with the new Gradient.RadialX and RadialY properties:
Chart1.Walls.Back.Gradient.RadialX := 123;
Chart1.Walls.Back.Gradient.RadialY := -321;
* Gradients provide a Balance property to apply more Start or more End colors:
Chart1.Walls.Back.Gradient.Balance := 40; // %, default is 50 %
* Canvas include new properties, methods and new overload methods:
Chart1.Canvas.FontZoom := 110; // % global font size zoom
Chart1.Canvas.Rectangle( R );
Chart1.Canvas.StretchDraw( R, Bitmap, Z ); // 3D stretch of pictures
Chart1.Canvas.Line( P0, P1 ); // P0 and P1 are TPoint
Chart1.Canvas.PolyLine( [P0,P1,P2...] );
Chart1.Canvas.PolyLine( [P0,P1,P2...] , Z); // for 3D
Chart1.Canvas.Pixels[x,y] := clRed; // now is read-write
Chart1.Canvas.RotatedEllipse( Left,Top,Right,Bottom,Z,Angle );
// returns if points are faced to viewer
TeeCull( P0,P1,P2 ):Boolean;
PointAtDistance( FromPoint, ToPoint, Distance ):TPoint;
* Anti-Aliasing.
Example of use of TeeAntiAlias procedure, to smooth curved lines on screen display.
* Rotated Ellipses.
New Canvas RotatedEllipse method to draw ellipses in 3D mode with rotation.
* Polyline method.
New Canvas Polyline method to draw multiple lines at once, passing an array of TPoint.
* StretchDraw 3D.
New Canvas method to display a bitmap in 3D mode with rotation.
* RichText drawing.
Example showing how to display RTF (RichText) formatted text over a Chart Canvas.
* OrthogonalAngle now supports from 0 to 180 degree.
Chart Legend
* Legend symbols can now display using a customized border.
By default, legend symbols use the Series border.
Chart1.Legend.Symbol.DefaultPen := False ;
Chart1.Legend.Symbol.Pen.Color := clRed ;
* Legend symbols can now be "squared" (same width as height).
Chart1.Legend.Symbol.Squared := True ;
Chart Walls
* The four chart walls now support transparency, even with gradient filling:
Chart1.Walls.Left.Transparency := 70 ; // % of transparency
* The Back wall can now be filled with an image in 3D display mode (orthogonal or not).
Chart Panel
* New Border pen and BorderRound properties,
to draw borders around chart panel in rectangular or rounded mode.
This new Border is drawn outside the current bevels.
The old "BorderStyle" property is now obsolete.
Chart1.Border.Color := clBlue ;
Chart1.BorderRound := 50 ; // pixels
* Chart Margins can be expressed as percentage or pixels.
Chart1.MarginUnits := muPixels ;
Chart1.MarginLeft := 10 ; // <--- 10 pixels
* Chart Panel now includes a Shadow property.
Chart1.Shadow.VertSize := 6 ;
All Series
* All Series styles now provide OnMouseEnter and OnMouseLeave events.

* All Series now provide a new method to order points by their corresponding "Label" (point text):
Series1.SortByLabels( loAscending ); // default is ascending
All Series Marks
* Series Marks new CallOut property, to change the appearance of lines connecting marks to series points.
New styles: Callout, rectangle, ellipse... and new properties: size, brush, distance.
Series1.Marks.ArrowShape.Style := asArrowHead ;
* Series Marks can now be individually customized (font, color, etc)
with Series1.Marks[3] do
begin
Font.Size:=14;
Color:=clSilver;
end;
Bar and Horizontal Bar Series
* Bar and Horizontal Bar series provide a new stacking style to display a single series "self stacked".
Series1.MultiBar:=mbSelfStack;
* New bar style: "bsBevel" and BevelSize property, to draw a rectangular bevel (in 2D and orthogonal 3D modes only).
Bubble Series
* Bubble series can now fill points using a gradient, with a default "radial" gradient style.
Series1.Pointer.Gradient.Visible := True ;
* Bubble Transparency
Series1.Transparency := 50 ;
* Small code to adjust left and rigth margins for Bubble charts:
var tmp : Integer;
begin
with Series1 do // (Series1 is a Bubble series)
begin
tmp := GetVertAxis.CalcSizeValue(RadiusValues.First);
GetHorizAxis.MinimumOffset := tmp;
tmp : =GetVertAxis.CalcSizeValue(RadiusValues.Last);
GetHorizAxis.MaximumOffset := tmp;
end;
end;
Candle Series
* New drawing style "csLine" to display a simple line using Close values.
ColorGrid Series
* ColorGrid series can now display Marks.
Series1.Marks.Visible := True ;
* ColorGrid can be displayed in "centered mode".
This mode means cells will correspond to grid values. This is now the default mode.

Series1.CenteredPoints := True ;
* ColorGrid now accepts a Bitmap image as a datasource of grid values
var tmp : TBitmap;
begin
// temporary bitmap:
tmp:=TBitmap.Create;
try
tmp.Assign(Image1.Picture.Graphic);
Series1.Bitmap:=tmp;
finally
tmp.Free;
end;

Each segment is composed of normal XY points.
This permits mouse hit detection (Clicked function) and OnMouseEnter events.
* A new property "Smoothing" draws level lines using a fitting spline function:
Series1.Smoothing.Active := True ;
* New event in Contour series "OnBeforeDrawLevel".
This event is called just before each contour level is going to be displayed.
One example of use is to change the level Pen for some particular level lines.
FastLine Series
* FastLine series now supports null points and can draw in "stairs" mode:
Series1.SetNull( 123 ); // <-- make null (empty) point index 123
Series1.IgnoreNulls := False; // <-- allow null points
Series1.Stairs := True; // <-- set "stairs" mode
Pie Series
* Pie series marks are now automatically positioned to avoid overlap as much as possible.
Series1.AutoMarkPosition := True ;

* All 3D Series (surface, contour, colorgrid, etc) include a new method
to add a bi-dimensional array (x by z grid of values).
var A : TArrayGrid; // = array of array of double
x,z : Integer;
begin
SetLength( A, 5, 7 ) ;
for x:=0 to 4 do
for z:= 0 to 6 do
A[x,z] := Random ;
Series1.AddArray( A );
end;
* Custom Colors for individual points are no longer overriden by ColorRange or ColorPalette.
* Small routine to perform "gridding".
The "Gridding" algorithm creates a regular grid (ie: surface) from arbitrary floating xyz points.
Chart Tools
* Annotation Callout
The annotation tool now provides a "Callout" sub-property, to display a line and a pointer shape, from the annotation to a given XY coordinate.

ChartGrid1.Series:=Series1; // <-- must be XYZ grid series
ChartGrid1.Grid3DMode:=True ;
New Chart Tools
*
3D Transpose tool
3D Transpose tool "rotates" any 3D series 90 degrees.
It does exchange x with z values.
Works with any Grid3D series (surface, etc).
A similar visual effect can also be obtained setting the Bottom and Depth axes Inverted
property to True, although the transpose tool modifies the real xyz data.
*
Extra Legend tool
