Re: "'ToolTip' cannot have a logical or visual parent" error on chart zoom

Hello! Having just the one MarksTip appears to work just fine for this, however I'm curious if it makes any difference and/or might be part of the problem. The route through the code is very similar for specifying a series or not (if one is not specified, it runs the same code over them all) - I thi...

Re: "'ToolTip' cannot have a logical or visual parent" error on chart zoom

Hello, I've had a look at this, and it does seem a common error - I've found examples of it here , here , here , here , and here . Unfortunately we haven't been able to reproduce the issue. TeeChart.WPF.dll calls the ToolTip via its ChartToolTip here: at System.Windows.Controls.ToolTipService.SetToo...

Re: Bars are displyed saperately w.r.t left and right axes

Hello Amol, Commenting out some existing code and adding in a couple more lines gives me the following: WindowsFormsApplication1_2021-02-08_10-37-19.png ArrangeBottomAxes(m_bar2); //m_bar2.MultiBar = Steema.TeeChart.Styles.MultiBars.SideAll; //tChart1.Legend.Visible = true; //tChart1.Aspect.View3D =...

Re: How to get the value of the right axis?

Hello, please find following a short code snippet which hopefully shows you how this can be done: private void InitializeTChart(TChart chart) { void CursorTool_Change(object sender, CursorChangeEventArgs e) { chart.Header.Text = $"YValue {e.YValue}"; chart.Header.Text += $" Right axis {chart.Axes.Ri...

Re: .NET 5 support plans for TeeChart v4 Pro in WinForms applications

I think it can be worthy to create an issue directly on winforms github as well
Yes, I think I will do that if I don't get a workaround I can use from the StackOverflow question. I'll leave it a couple of days, and if I get nothing useful I'll post on github.

Re: .NET 5 support plans for TeeChart v4 Pro in WinForms applications

So looking forward for it. So are we! It seems that the .NET 5.0 Windows Form designer still doesn't have exactly the same functionality as the .NET Framework Windows Form designer, which means we can't implement the functionality you mention until we have a resolution to the issue which I have det...

Re: Changing appearance of points in Points series

Hello, yes, the Points series has a Pointer property which you can use to change the color, style, and width of the Points series pointer. However, to simply make the series invisible without using the Series.Visible property - which means that Axis labels and Legend(s) continue to be rendered - an ...

Re: Show logo in chart (c#)

Hello, I would say the easiest and most powerful way to draw images to the Chart is to use one of the Draw overloads within one of TChart's custom drawing events. Here's an example of what I mean, using an image which has been added as a resource to the project: private void InitializeChart(TChart c...

Re: 3D chart is not working in ASP .NET Core 3.1 Example

Hello, What do you mean by "different version"? You're right, my mistake, they are the same version. So if I need an ASP .NET Core 3.1 web application with 3D pie chart and mouse functionality (tooltip, click, zoom, scroll, etc.) - what is the option for me? No options with your library?
