Hi Yeray, OK, I just solved it, it should look like this: // Get Cluster extend in pixels XSize := PCAChart.BottomAxis.CalcSizeValue(FClusterAnalyser.GetMaxDistanceX(ClusterIndex)); YSize := PCAChart.LeftAxis.CalcSizeValue(FClusterAnalyser.GetMaxDistanceY(ClusterIndex)); ZSize := PCAChart.DepthAxis....

Hi Yeray, >Maybe the chart hasn't been drawn yet when you call these methods? Yes, that was the first obstacle, but after solving that the plot is still off. Now I tried the approach that was suggested by Narcis, drawing cubes in the TChart OnAfterDraw event. In this case the extends of the cubes se...

Hi Narcis, >I'm afraid such a series doesn't exist. However, custom drawing is still a valid option as you can convert from axis values to screen coordinates and viceversa >using methods like CalcPosValue and CalcPosPoint. At the moment I am creating individual TPoint3DSeries for each Cluster/Rectan...

Hi Narcis, Thank you, but this was not what I meant. I need a series that contains individually sizable transparent rectangles as Items where I can set the X,Y,Z extend for each rectangle separately in units of the plot and not in pixels. You have now created one cube which size is given in pixels (...

Hi, I am currently using TChart 2011 and I'd like to draw multiple semi-transparent rectangles with different X,Y,Z extends like shown in the clustering example. Capture.JPG Which series I do have to uses to achieve that, because the normal TPoint3DSeries does not allow for varying X,Y,Z extends per...

Hi, in OpenGL mode all shown text rotates with the graphics/axes which makes it unreadable most of the time (Please see: OpenGLModeText.png). In normal 3D mode the text is always displayed perpendicular to the viewing axis. (Please see: Normal3DModeText.png). This is the preferred solution because i...

Hi Yeray,

the size of the chart is fine if I choose "orthogonal" but the font size is still ridiculously small!

best regards,

xray

Hi Narcis,

thanks for the workaround, it solved the problem!

best regards,

xray

Hi TChart Team, to create high-quality/high-resolution bitmaps from OpenGL surface series I tried to export bitmap (.BMP) files with higher resolution by activating the Chart editor, selecting the Export page and entering a size of for example 3000 pixels width. If I save the BMP file with these set...

Hi TChart Team, I just installed V8.05 and this bug is still not fixed. This is unfortunately a real showstopper for our next release. Can someone please point me to the source file where this bug is located and give a hint what is going wrong. Then I can try to fix it myself. Tips for other workaro...

Hi Yeray,

this can't work because:

Chart1.Axes.Left.IsDateTime

is a function not a writable property.

Any other hints?

Hi TChart Team, I can switch on/off the DateTime property for the Vertical Axis of a TColorGridSeries by selecting this series in the editor window and then activating the "General" tab. There you find this switch in the "Vertical Axis" group box. How can I do that programmatically for a TColorGridS...

Dear TChart Team, I have found a bug in Version 8.04. The display/bottom axes of THistogramSeries is obviously wrong. The data is displaced on the x-axis. To reproduce this: Add a HistogramSeries to a Chart. Then fill the HistogramSeries using this code: procedure TForm2.FormCreate(Sender: TObject);...

Hi Narcis, thanks for the fast reply! I have another remark concerning the Depth Right Axis title. Unfortunately it is only possible to display this title perpendicular to this axis. For other axes like the Left and Bottom axis it is possible to display the titles along the axes. This is of course t...

Hi Steema team, I just upgraded our software package from TChart 7 to TChart 8.0.2. Unfortunately it seems that a small bug was introduced in the new version concerning the painting of the title of the Depth Right Axis in OpenGL mode. The title is now misplaced and is displayed in front of the chart...
