Re: Draw 3D curves and shapes

There's an example without code here. I'll try to find and attach the code here if possible.
I cannot download the file from the link you provided. Can you attach it here or email it to me? Thanks!

The same procedure yields different axes properties

To draw two PolarSeries Charts, and using TSubChartTool draws the second Chart. The two Charts (named TheChart and SubChart) have the same sizes and arrange horizontally (see the Fig. attached). 1. To keep the axes properties of the two Charts are the same, I write a procedure as follows: procedure ...

Re: How to draw Polar Series using Custom Axes

There are two Charts (Original Chart and TSubChartTool.Charts[0].Chart) and a TeeCommander. The TeeCommander always handles with the Original Chart. In order to move and zoom the two Charts, respectively, how to make the TeeCommander to alternately control one of the two Charts?

Re: Assign TSubChartTool’s ChartRect is invalid

Thank you for your reply.
Taking the horizontal axes as an example. If both of the axes increments of the SubChart and MainChart are 400m, but their sizes are different in pixel (see Fig. above). I hope that the ratio of actual increment and screen increment of the two charts are the same.

Re: Coordinated control of two Charts

When the Mouse moves on the chart, the ChartAxis Label’s Font changes to the Default Font by itself. Assigning LabelsFont.DefaultFont := false makes no difference. Why is that?

Re: Assign TSubChartTool’s ChartRect is invalid

The SubChart and the MainChart are out of proportion in size.
How to make the horizontal and vertical axes of the two charts to be the same scales, respectively?

Re: How to draw Polar Series using Custom Axes

Yes, Your modified project works fine. However, how to use the BeforeDrawValues procedure to set the ChartRect’s properties, if the PolarSeries are dynamically created?

Assign TSubChartTool’s ChartRect is invalid

Using TChart and TSubChartToolD draws LineSeries (called MainChart and SubChart). The scales and increment of horizontal and vertical axes are the same, respectively, but the sizes of the two charts are different. I can determine the Width and Height of the SubChart’s ChartRect from the MainChart.Ch...

Re: How to draw Polar Series using Custom Axes

Thank you for your advice. I use the TSubChartTool, and it works. However, the first chart always locates at the center of the Panel, although I try to set its Width, ChartRect.SetLocation and (ChartRect.Left, ChartRect.Right). I hope that the two charts would be horizontally arranged, do not overla...

Draw 3D curves and shapes

1. Is it effective to use some Point3DSeries, ShapeSeries and SurfaceSeries on one Chart concurrently? In addition, is the Point3DSeries generally used to draw 3D curves? 2. It seems that the TopAxis does not appear on the Point3DSeries Chart. If the three TChartAxes are required as shown in Fig3D, ...

Re: Coordinated control of two Charts

When the Minimum and Maximum of an Axis are equal, there is only one Label on the Axis. That is correct in general. If the horizontal Axis and vertical Axis are isometric, and more than one Labels are required, is it possible to draw a number of Labels on the one-label Axis from the Axis’s Start Pos...

Re: Coordinated control of two Charts

Using the same codes in another program, there are two weird results: 1.Axes Labels do not have the same size (see Fig-1), although I use the same codes to set the Chart and axes properties. 2. When click and zoom in the Sub Chart area, the Curves exceed the range of the Sub Chart area or CustomAxes...
