RadCartesianChart fails to render Y-axis labels on Android tablet; but, same code successfully renders labels on Android phone

Hello,

I've tested my Visual Studio code that uses the RadCartesianChart on a Samsung Galaxy Note10+ phone and it works as expected. However, when I test this same code on a Samsung Tab A7 tablet, the Y-axis labels are not rendered. (This area on the screen is empty.)

See the attached screenshots from both devices.

Hello Donn,

Thank you for the image. I am not sure how to assist further, as on my side I cannot reproduce the behavior when testing on a real devices (I tested on Pixel, Samsung, Xiaomi, etc.). Still I do not have the concrete Samsung tablet device.

Test scenario:

  1. Set a definitive width and height to the chart and position the chart in the center of the screen
  2. Wrap the chart in a border with definitive width and height

Additional info:

  1. Send exact steps to reproduce the behavior.
  2. What is the Android version of the Samsung tablet?
  3. Sample project where the issue occurs.

Regards,
Didi

Didi: I've located another Android tablet (running Android 14) and tested my code there. The y-axis labels are rendered correctly (as they are on my Samsung phone). I'm attaching a photo, below, of the running code.

So, the Telerik control's labels render correctly on the Samsung phone, and, on the 2nd, no-name, tablet. However, on the Samsung Tab A7, the control fails to render the y-axis.

Thoughts as to how to resolve this?

Thanks!

Hi Donn,

You can send the code in a support ticket, here in the public feedback item or in a GitHub repo. 

If you do not want to send the code publicly, you can open a support ticket and attach the code there. Please note that I do not need the original data you use, just a sample chart definition. For example in my test scenario I used the example provided here: https://docs.telerik.com/devtools/xamarin/controls/chart/series/cartesian/bar-series#example  You can test this example and let me know whether the issue occurs on tablet.

Didi,

Thanks for the response. I only have the A7 tablet and the phone. So, won't be able to test on another tablet.

 

Is there a way for me to send you my chart code offline?

 

Thanks!

Hello Donn,

Thank you for the details.

I do not have a Samsung tablet, so I created a tablet emulator with android 34 and cannot reproduce the behavior with the missing labels. I have attached an image.

Could you please test on a different tablet than Samsung and let me know the results. Also send the chart definition you use on your side, so I can test in my sample app.

Regards,
Didi
