[LineChart] How to Darw "NSString" on xAxis? without Realm.io

[dadigua2333]

In the "Charts" old version, I use This API to draw xAxis : ChartDataEntry *entry = [[ChartDataEntry alloc] initWithValue:val xIndex:i];

but, in the new Version, It disappeared! I mean: I only find This API
ChartDataEntry *entry = [[ChartDataEntry alloc] initWithX:11.01 y:35];
Two parameters are of type double !

I try to use Realm.io
But my project loaded in first time, the boss demanded that without the data, the data is added gradually.
Then the Xcode error: Nan
That's to say: when using Realm must be initialized data, this way doesn't work for me

How should I handle? Thank you!

I have the same problem.
My xAxis shows date before, now all have been changed to double value...

another question: What does data parameter used for?

- (nonnull instancetype)initWithX:(double)x y:(double)y data:(id _Nullable)data

I also need to show strings on the x axys. I hope it will be possible in the new version.
