LeftAxis Labels will disappear

[cartmanguo]

I need to update the linechart dynamicly,when a new value arrives,I create an entry and add it the the dataset.This problem happends no matter autoScaleMinMaxEnabled property is on or off
Here's a screenshot:

call notifyDataSetChanged() after you add new ones.

[cartmanguo]

actually,I called notifyDataSetChanged() everytime I add an enrty,so this is not the problem
I'll try to make a demo to reproduce this problem and show it to you

[cartmanguo]

here's a demo:https://github.com/cartmanguo/reproduceissuecharts
drag the charts project to it and run,tap the add bar button,you will see this problem I described.
Thanks. @liuxuan30

You add entry by dataSet interfaces, without letting chartData know the max value would change.
you should add entries on data's level via API lineChart.data?.addEntry(entry, dataSetIndex: 0)

still doesn't work...

and if I set autoScaleMinMaxEnabled to true, the same thing happens in issue #2053

@cartmanguo first, 'still does not work' can't help. And don't mix up different things together. I tried your project and lineChart.data?.addEntry(entry, dataSetIndex: 0) works on my side.

I'm sorry If I mixed up two unrelated issues,I just think they both have something to do with caculating,apolygize again...
I changed that line to lineChart.data?.addEntry(entry, dataSetIndex: 0),but the left axis labels still not displaying after I add the second entry,I use the latest commit of Charts

Today I realize that maybe it's because I didn't set the granularity property,so I set it to 0.1,it seems to be ok now.

Cool, i just used what you uploaded and it works after adding that line of code
