setVisibleXRange conflicts with granularity #2260

Open acegreen opened 7 years ago

acegreen commented 7 years ago

I have a dynamic chart and during setup I do:

        lineChartView.xAxis.granularityEnabled = true
        lineChartView.xAxis.granularity = 25
        lineChartView.xAxis.forceLabelsEnabled = true
        lineChartView.xAxis.labelCount = 20

when checking my xAxis label formatter for values, I get the expected 0, 25, 75, 100 etc

When I set my xRange though to:

lineChartView.setVisibleXRange(minXRange: 25, maxXRange: 500)

the xAxis label values are incremented by 30

EDIT: just a note that as soon as I zoom in a tiny bit, the scale reverts back to the 0, 25, 75 etc.

@liuxuan30 any thoughts on how to tackle this? seems like an issue with limitTransAndScale() when its fullyZoomedOut

maybe a bug, but I don't have time to look into it
