Questions
Dear Support, I have SciChartSurface in fragment (Xamarin Android). I added Xaxis (DateAxis), Yaxis (NumericAxis), standard modifiers and few XyDataSeries as FastLineRenderableSeries. Everything is working fine (screenshot 1). But something strange is happen when fragment with chart is Paused -> Stopped and then Started -> Resumed. Xaxis and Yaxis are not visible. All dataseries are not visible. But I debugged and all data is there. Even rolloverModifier is still working and correct data values are displayed in labels (screenshot 2). It does not happen every time – it depends on what external intent stopped fragment.
I’ve tried reinitialize chart (clear Xaxis, Yaxis, remove modifiers, remove renderableSeries are reinit all with new variables) and it does not help. Only fragment dettach -> attach helps or screen orientantion change (it reinitializes fragment)
Could you tell me any suggestion what can I check or how to force to redraw whole SciChartSurface? (hiding it and showing it does not help – effect is the same. Only fragment dettach and attach helps (this is my workaround at the moment).

- It looks like that there is some exception during rendering of chart that’s why you get blank chart – do you see some errors in logcat? Also can you provide a code or project which reproduces this issue because it’s really hard to tell why this happens without seeing the code?

Thanks for reply. It is NullPointerException in scichart.drawing.opengl lib (log below). It will be a lot of effort to prepare working example without sharing code which I can’t share, so if I do not find solution then I’ll probably stay with my workaround…

- I’ve tried to fix this exception based on stack trace which you provided but without solution to reproduce I can’t be 100% sure. Anyway fix should be available with our next nightly build ( v2.2.2.2410 ) which should be published abit later today. Can you try it and let me know if the issue is resolved?

Yes I’ll check it when it will be available. I’ll let you know. Thank you.

Dear Andrew. Thank you. Just tested 2.2.2.850 and unfortunatelly it is the same. When fragment is restarted, then reinitialization routine work well until adding RenderableSeries to SciChart. After it exception occurs and X/Y axes disappear and data is “hidden” – only grid is visible as on screen above. This does not happen every time – it depends what is user intercation sequence and what intent stopped fragment. I can reproduce error every time doing the same test sequence in app*. GC is also not running in this moment. When I reinitialize with re-attach fragment then everything is working well. At the moment I’ll stay with my workaround, but later I’ll try to prepare example with this issue because re-attaching fragment is not elegant (and not efficient).
*For example:
1. not working sequence: I open app -> open fragment -> load data from internal csv file (stored in assets) -> initialize chart (x/y axes, modifiers, dataseries etc.) then data displays correctly. Next I try to open file (FilePicker plugin) and fragment is stopped. After backing to fragment (fragment is started and chart is reinitialized) all data disappear.
2. working sequence: I open app -> open fragment -> load data from external csv file (FilePicker plugin) -> initialize chart (x/y axes, modifiers, dataseries etc.) then data displays correctly. Next I repeat above sequence with opening file from internal csv file (stored in assets) and… it is working. Next I try to open another file (FilePicker plugin) and it is still working. Nothing can corrupt chart at the moment. Strange.
