Re: Display settings and font size

Hello Ed, One thing I thought we could try in the meantime is exchange *.exes - I send you the Release build I create here to see if it behaves the same at your end, and you send me yours. In this way we should be able to determine if it's the build version of Delphi that's at issue or not. Here's m...

Re: Running Demo failed

Hello,

Have you tried the example code on our GitHub repo?
https://github.com/Steema/TeeChart-VCL-samples

When I open Tee9New.bdsproj under the TeeNew folder and run it with Delphi 10.2 Update 3, I get:

Do you get the same?

Re: Display settings and font size

That is similar to what I am doing, but I am using Delphi 10.4. Did you try that? No, I'm afraid I didn't - I don't usually work on the Delphi side of things and only have access to Delphi 10.2 Update 3 at the moment. I think I might be able to get hold of a more up-to-date version of Delphi next w...

Re: Marks on bar series

Hello! How about: Bar _bar = new Bar(); private void InitializeChart() { _tChart.Series.Add(_bar); _bar.FillSampleValues(); _bar.Marks.TailStyle = MarksTail.None; _bar.MarksOnBar = true; } which gives me: TeeChartPro_2020-08-03_12-36-23.png

Re: Cannot Process Fitting

Hello! Surely, as this is a TeeChart defined error code, Steema will know what triggers it, and how to avoid it. There is an exception string: TeeMsg_FittingError :='Cannot process fitting'; and this string is used to raise one exception, and this exception is raised in TeePoly.pas at line 183: bds_...

Re: How to set the vertical line spacing

Hello! still not sure about this one - maybe it's the values in your data[] object, becuase when I use code such as this: private void InitializeChart() { var rnd = new Random(); var line1 = new Line(_tChart.Chart); var day = DateTime.Today; for (int i = 0; i < 100; i++) { line1.Add(day, rnd.Next(1,...

Re: Axis value repeat

The line is composed of continuous points. When I zoom the chart, duplicate numbers appear on the axis. How should I avoid this situation. You can set the ValueFormat of series points and axis label values to any of the Standard or Custom numeric format strings, e.g. private void InitializeChart() ...

While I am using TeeChart 3.5, it seems to be a the same issue you are seeing. Was hoping to hear if this issue was resolved.
As I explained in my last message, this is not a TeeChart issue (an issue pertaining to an app component), but is an issue of the configuration of the app itself.

Another thing related to vertical lines. When I zoom in I got this non equal spacing axis lines (see red lines which are bigger), How do I make sure these has the same spacing.
How are you adding values into your series?

Re: The 3D chart created by IsoSurface not fluent when rotating

I created a 3D chart using IsoSurface. It can run smoothly when 1000 points are loaded, but when I append to 3 million points, the rotating chart is not smooth. How should I optimize it. Here I'm using this code: private void InitializeChart() { _tChart.Aspect.View3D = true; _tChart.Aspect.Orthogon...

Re: Zoom gone after setting bottom axis max points

As soon as I run this: chart.Axes.Bottom.Minimum = 0 chart.Axes.Bottom.Maximum = CurrMaxPoints It zooms back out. I want it to stay focused on the same area of the graph. I'd have to see more of your code to have a clear understanding of what's going on, but staying focused on the same area of the ...
