描述

I'm having troubles getting setVisibleYRangeMinimum to work properly. I expect it not only to zoom out to minimum range but also to display all the labels on Y axis.

Here's my code snippet:

data.addDataSet(set1)
wrapperGraphView.data = data
wrapperGraphView.setVisibleYRangeMinimum(300, axis: .left)
wrapperGraphView.notifyDataSetChanged()

Here's the result: img_1241c700dc06-1

It's zooming out properly, but does not display all the labels up to 300 on Y axis.

It seems to be similar to https://github.com/danielgindi/Charts/issues/199 but none of the suggested solutions worked for me.

Any suggestions would be appreciated.

研究方向
Investigate the Y axis rendering logic in the Charts library, focusing on how labels are generated when `setVisibleYRangeMinimum` is set. Look at classes like `ChartYAxisRenderer` or `YAxis` to see if labels are being clipped or limited. Check the referenced issue #199 for similar past work. The fix likely involves ensuring the label count or positioning respects the minimum visible range.
