Is this Error series or ErrorBar series ?
ErrorBar does not allow changing the ErrorStyle property.
("essTop" is the default in ErrorBar series and the only supported style)
We can add support for the additional styles in future versions.
Error series. It is a defect and has been fixed in the .NET version: http://bugs.teechart.net/show_bug.cgi?id=529 in id=529 there's an attachment with a form which tests a number of Error series variables. This defect is related to the use of CalcPosSize with logarithmic axes and the fix involves the addition of a new overload to this function. If you look carefully at the example you will see that the Error line does not extend from 9.3 to 10.7 as it should, but from 9.7 to 10.3. Fixed. Error size for horizontal style (left, right, left right) was being calculated using the vertical position (YValue) instead of XValue. |
If you have ErrorBar series and you set its error style to LeftRight, the error is drawn incorrectly, the problem only occurs when the error value is biggest than Bar value. Seems the problem is introduced when we fixed the bugs numbers TF02014259 and TV52015184. The same problem occurs in TeeCharFor.Net version, bug number=529. The error is drawn correctly if you add Bar values biggest error value. Next code reproduces the problem: type TForm1 = class(TForm) Chart1: TChart; Series1: TErrorSeries; procedure FormCreate(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} procedure TForm1.FormCreate(Sender: TObject); begin Chart1.View3D:=false; Series1.AddErrorBar(10, 0.3, 0.7); Series1.ErrorStyle := essLeftRight; Chart1.Axes.Bottom.SetMinMax(9.0,11.0); Chart1.Axes.Left.SetMinMax(0,1); end;
