zooming .NET MAUI

[Senso4sLab]

The zooming does not work when the .NET MAUI project is used. I tested on the Android platform.
I came across that this feature is not supported yet, is it true?

When the graph, the first time, is shown the tooltip does not work at first press. You have to tap on the graph a few times, then the tooltip usually shows.

I did some additional tests I found out that by changing MinLimit and MaxLimit values the graph is not updated. I have to double-click on the graph to force the axis to update. Is it possible programmatically force graph updating?

Hi @Senso4sLab, zooming has some issues on MAUI but sadly there is not much we can do to fix that.

Take a look at dotnet/maui#6553

I found out that by changing MinLimit and MaxLimit values the graph is not updated.

it should, how are you doing it?

Beto thanks for reply. let's start from the basics. Please check attached images. In the first image x axes is not updated, when I just click on graph I get dates. The second problem is y axes, I do not know why steps are not linear. Third problem is not visible, but when I click on point the tooltip does not show, I have to click around the point and back on point.

Zooming and panning does seem to be completely broken in .NET MAUI targeting desktop/WinUI3. It seems to constantly think left-mouse is pressed, and panning does not seem to be functional at all. It "clips" back to position

Zooming now works much better with a4045c6 but I cannot find a way to improve zooming in desktop devices, I raised an issue to Maui:

dotnet/maui#16130

This is finally working properly on beta.950, it works on all the platforms properly, thanks for the report.
