CursorTool Z position in Point3D series

A CursorTool does not change its Z Depth axis position for a Point3D series. It seems that the Z Depth axis value for the cursortool is always the Z value of the last data value added to the series. series1.AddXYZ(1,1,1); series1.AddXYZ(3,2,5); series1.AddXYZ(7,4,3); series1.AddXYZ(2,3,2); series1.A...

Narcis, Did these changes happen to address the issue of "Horizontal Bar series does not show the correct bar width after zooming vertically. If BarWidthPercent is 100, the horizontal center of the bar position appears lower on the vertical axis than it should be." http://www.teechart.net/support/vi...

HorizBar CustomBarHeight behavior changed from 7.06 to 7.07

The behavior of Horizontal Bar series CustomBarHeight has changed from version 7.06 to 7.07. I am using small values of CustomBarHeight to create many thin horizontal lines that can be located at any vertical data value and whose horizontal width can be varied. By varying the value of CustomBarHeigh...

Obtain version of TChart at run time ?

Is it possible to obtain the version of TChart VCL at run time using Delphi ?

The behavior of HozirBar series CustomBarHeight has changed from 7.06 to 7.07 and I'd like to execute different code depending under which version I happen to have compiled the component.

Narcis, For my application, custom labels has an issue in that their label separation is not automatically recalculated to remove overlap if the chart or its form is resized.

Different axis labels for Top and Bottom when aBothHorizAxis

When a series is configured to use both horizontal axis, it is possible to assign a different axis label for the top and for the bottom axis ? I would prefer to do this in the series1.AddXY method rather than OnGetAxisLabel event. OnGetAxisLabel fires for axis labels other than those data values act...

Narcis, Chart1.View3D := false; to view it as 2D. Nothing will be displayed on the chart (since LinePen and OutLine are invisible). But the saved .pdf will show a black line connecting its points. You can add Series1.Pointer.Visible := true; to see the points on the chart. Then the saved pdf will ha...

Also, can the size of the printer paper on which the chart to be printed is displayed be increased so that it occupies more of the ChartPreviewer's panel (the gray to white gradient panel) ? It appears to be a fixed percentage. I'd like to make the chart appear larger to the user. I've tried using C...

Label Separation when use Axis Items.Add

Axis Items.Clear followed by Items.Add results in every axis label being displayed and possibly overlapping. Is there a way to have the chart check for overlapped labels before drawing them as it normally does with standard axis labels ?
