I’m seeing a crash log that happens only some times (it’s not consistently reproducible) that looks like this:

Any idea what could be happening?

I have a line chart and need to implement textAlign: left property for tickLabel on yAxis. I have found some way to do it on the forum, but it does not work in my case:
xAxis.setAxisTickLabelStyle(new AxisTickLabelStyle(Gravity.CENTER, Layout.Alignment.ALIGN_CENTER, 5, 0, 5, 0));
I get the error:
Alignment cannot be converted to int
But according documentation AxisTickLabelStyle class get 5 int arguments. Can you help me please how to solve it!

Hi all,

Bit of a weird question here again – sorry.

I’m not sure if this is possible, but I’m looking to have an android device take pictures every x minutes, and I’d like to display them in a chart with a shared axis with a few other charts. A user will ideally be able to see each of these snapshots associated with the time that they’re taken, and on press expand them into a carousel view with the selected image as the current.

The on press and carousel bit will be straight android code, but I was wondering about displaying images on charts – is it possible? I poked around a little bit, and for WPF, I saw

I was wondering if the android libraries can do similar, and if so, do you have any examples/code snippets?

The other potential approach I found was using the Sprite point marker API, although I’m not sure the scope of images it can render?

Would either of these approaches be feasible, and do you have any examples/tips? Attached is the current status of my charts, and I’m hoping to put images in the red boxes on the second chart (I just put a column chart as a placeholder there for the moment).

Also, I just wanted to say thanks for all the fantastic support your team has provided.

Hi, I’m a software engineer. My organization is ready to purchase your solution for our project(Android, IOS), but I have some questions:
1. Can I get a callback when the visible area on the x axis changes? This is necessary to dynamically upload data to the end of the graph when the user scrolls back.
2. Change the position of the tooltip and place in the upper corner of the chart?
Thank you for your time and hope for further cooperation.

Is there a way to just change the values of the pie segments so it get updated on the donut chart.
If I remove and add the pie segments again it works, is this the correct way?

Also I can’t find any documentation around the donut for android/xamarin

Is it possible to give an arrow type style to the axes? As seen in the attached image.

It would be perfect!

Otherwise, I would like to know if it is not possible, not to take into account this characteristic in my development.

I hope you can give me a clue please. Thanks in advance.
