Hello,

An axis needs a series visible with values assigned to it to be drawn. So, you have to assign your series to it:

Hello, The MarksLocation property is thought to be used with the automatic positioning of the marks, not with the Custom positions you are using. Ie: procedure TForm1.FormCreate(Sender: TObject); var i: Integer; begin Chart1.Legend.Hide; for i:=0 to 3 do with Chart1.AddSeries(THorizBarSeries) as THo...

Hello, We've discussed this through mail but if anyone else comes here and wants to know the solution to the issues exposed here we go. Actually MD chart will be refresh every time and lines will be drawn in different positions. So that every time on hover of line we need to show the title. That's t...

Hello Ferenc, Indeed, there's the RotatedEllipse method to manually draw rotated ellipses. Here it is an example of usage: Tee9new_2018-11-13_11-34-34.png You could use it (ie at OnBeforeDrawSeries event) to draw them behind your point series. Ie: Project1_2018-11-13_11-44-59.png uses Series, TeCanv...

Hello Mark,

Try calling CheckDataSource on the LLineSeries to force it to retrieve the new values:

Hello,

I've tested it both in VCL and FMX and, as you say, the problem isn't reproduced.
It's difficult to say what's going on without reproducing the problem in a simple test project.
Please, try removing things from your main project to try to find what makes the difference.

Hello,

You can use the series VisibleCount function to get the number of points currently visible.

Hello, I could reproduce it in ActiveX using VB6, and also in TeeChart VCL. I think the issue is soon or later you'll have to find a compromise. Here it is a trick you can do if you are not going to have values far from that ~939. The idea is to substract the integer part to represent the data witho...

Hello, Regarding the RangeError, debugging your sources, I see a couple of issues: First, you are calling your startRefresh method at the end of your redrawMdLine: function redrawMdLine() { //... if (isLive) { startRefresh(); isLive = false; } } And the startRefresh code calls the redrawMdLine funct...

Hello Ed, First note the number of IDEs and the number of platforms in each IDE increased with the years directly affecting the size of the installations, and thus the installers. It is not the same to distribute the units for win32, than the units for win32, win64, android, ios and osx. For referen...

Hello Jim, ok, that solved the problem! Many thanks. I'm glad you finally could install it. Now back to my own bugs and trying to solve the 3D plots with the proper aspect ratios when rotated. Looks like I must move to different plotting software. I'm sorry to hear you are so disappointed with this ...

Please, create a "TeeMaker" folder inside the "VCL.Tests" folder you just created.

Hello,

Have you tried using the TBar3DSeries?

Please give a few more details. Exactly where does one add the missing folder? I would think one should not wait until a version before correcting a problem that prevents the software from being installed. Sorry for not being clear enough. As the error message says, TeeRecompile tries to copy "TeeM...

Hello, This is just to inform I have been able to fix the bug ( #2116 ) so the next release will include it. If you want to fix it in your sources, you just have to add this line at the end of the THighLowSeries.DoBeforeDrawValues method, in ErrorBar.pas: Procedure THighLowSeries.DoBeforeDrawValues;...
