Charts ScaleX problem

[quoctc]

I want to auto scale chart by scaling X to fixing the size of my data. So my charts will not zoom in too much. It's will keep the same space between two points of x values in the chart. But when I call to scaleX by call this func:

chartView.zoomToCenter(scaleX: scale, scaleY: 1.0). It generates weird scaleX number, not my expected number

Here is the debug:

What did you expect to happen?

It's should be my scale nubmer that I'm giving. Or there is any function in the lib support it

What happened instead?

It's scale with a bigger number
