Re: Adjust positions of marks in a TPointSeries?

Thanks, it looks like that might work - although more complex than just a position option for point markers. I will try it.

Adjust positions of marks in a TPointSeries?

Using the mark strings to identify points in a TPointSeries works but I would like to make a small adjustment in their positions of the labels. The labels are a little too high - especially if I use a larger font. I would prefer the text to be centered vertically on each symbol.

Thanks,

Jim

Re: Coloring point symbols on a line series.

Yes, here is how I do it: As you noted: color the series series.seriescolor := ColorDialog.Color; But then color the fill of the marker symbols series.Pointer.Color := ColorDialog.Color; and color the line around the edge of the symbol series.Pointer.Pen.Color := ColorDialog.Color; (assumes series i...

close a form with a TChart

Is there something special one should do when closing a VCL form with a TeeChart? I have just tried using the FullDebug option of the FASTMM4 unit to check for leaks etc. and it crashes every time when I close the form. It complains about accessing an already free-ed object. The references it provid...

Re: Lines between 3D points?

Oh, I just discovered that the 3D vector series I needed actually does exist. The TVector3DSeries series is in the VCLTee.TeeSurfa unit. Now the problem is that some lines display too light (see the screenshot). Perhaps they are drawn but much too light.

Re: Lines between 3D points?

I tried that and it works except for one odd problem. If there is a line segment connecting the last point to some other point then when I rotate the chart with the mouse in some views a line suddenly appears connecting the last point to the first point. If no line connects the last point then this ...

Re: Lines between 3D points?

So I would then have a new series for each line segment I need to draw? It would work but a generalization of TArrowSeries to 3D would be much more elegant and would make 3D just a generalization of 2D.

Lines between 3D points?

I have a TPoint3DSeries and I would like to draw lines between various pairs of points (not just connect them in sequence). What is the best (simplest) way? For 2D I used TArrowSeries and that worked well. Is there a 3D equivalent?

Thanks, Jim

Re: zero mark does not always display

I will try to create one but this problem is in part of a rather large program.

zero mark does not always display

I have axes set to automatically display. Results usually good but sometimes I get a result shown on the attached screenshot. The '0' mark is not displayed on either the left or the bottom axes. Is there an option to force the '0' to always be displayed?

Re: Coloring point symbols on a line series.

Has this been answered somewhere? When I use .SeriesColor it changes the color of both the line and the fill color of points. I want it possible to have different colors.
