tree chart is showing on activity but not showing in fragment

[hrgdeveloper]

hello , i am using any chart trial version 1.1.2
this code is working on activity and the chart is showing but when i use exactly same code in a fragment that is inside a viewpager a white screen is showing whit out any chart trial version lable and nothing show up. i have logged data and evry thing is okey . i dont see any log message from any chart in log cat

if i update library to 1.1.3 or 1.1.4 the chart wont show up even on activity . even with your sample code .
https://github.com/AnyChart/AnyChart-Android/blob/master/sample/src/main/java/com/anychart/sample/charts/TreeMapChartActivity.java

this is the code that i am using on activity and chart is showing . but on the fragment after getting data from live data i do the same thing and only a white screen is showing

I got stuck for this too. Tree chart will show the first time i enter the fragment. But when i navigate to another fragment and back to it, it may possibly disappear (so strange) and only left with the watermark. However, when i back to the home screen (making the activity stopped) and reenter the app it shows again. I am using tree chart to show file size like a file explorer. What makes me quite confused is that it POSSIBLY shows white screen and sometimes works.
