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...

6 days no reply at SO. Looks like we need to go "github route"..

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? I'm not sur...

Re: Programmatically Creating DrawLineItem Error Null Handles Exception

Hello Joseph, I think the reason is that you are using the parameterless constructor of DrawLineItem, which means that EndHandle will throw an error (following code is from the sourcecode): public Rectangle EndHandle { get { return RectangleFromPoint(tool.AxisPoint(EndPos)); } } It will throw an err...

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

Hello, Where I can find an example of exporting to image? Although it uses a different version of TeeChart, the TeeChart syntax is the same as that shown here .

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

But chart is still 2D. Is that by design or a bug? Does your web component have functional parity with WinForms or where can I read abiut all it's limitations? It's by design. In that example you will see that the Chart is being exported as a JavaScript Chart which renders to HTML5. The JS/HTML5 Ch...

Re: Problems with Copy-Paste the whole chart.

Hello, Any updates on this? It's a real pain to create similar complex charts from scratch without be able to simply copy them.. You don't have to create them from scratch, as I mentioned, you can use the TeeChart native template files. To make it clear, please find a short screenshot gif I made to ...
