xAxis.axisMaxValue is never considered

[velthune]

As in title, I set the property but does not change anything:

let view = LineChartView()
view.xAxis.axisMinValue = 6
view.xAxis.axisMaxValue = 14

on 'axisMinValue' change, graph is drawn as I expect, but changing 'axisMaxValue' nothing happens.

currently it's just for y axis. for x axis, use setVisibleXRange()

@danielgindi will v3 solve this issue?

[velthune]

No, I've already tried using "setVisibleXRange", but still doesn't work unfortunately

@velthune it should work, I have tested it.

If you call this method, chart must have data or it has no effect

which means you have to call setVisibleXRange() after chartView.data = chartData

[velthune]

Can you try with this values?

X - VALS
    [-1...15] with -1 and 15 includes

Y - VALS
    X: -1 Y: 0.0
    X: 1 Y: 0.0
    X: 3 Y: 0.0
    X: 5 Y: 0.0
    X: 7 Y: 0.0
    X: 9 Y: 48.0
    X: 11 Y: 24.0
    X: 13 Y: 0.0
    X: 15 Y: 0.0

These are values, and I want too see graph in range [0...14]

I use:

self.viewChart.xAxis.axisMinValue = 0
self.viewChart.setVisibleXRange(minXRange: 14, maxXRange: 14)

My chart is drawn in this way:

But I expect that points will centered on days segments.

my bad, seems I misunderstand.

/// Limits the maximum and minimum value count that can be visible by pinching and zooming.
/// e.g. minRange=10, maxRange=100 no less than 10 values and no more that 100 values can be viewed
/// at once without scrolling
public func setVisibleXRange(minXRange: CGFloat, maxXRange: CGFloat)

Try this, should work:

_chartView.data = data;
[_chartView setVisibleXRangeWithMinXRange:1 maxXRange:15];
[_chartView moveViewToX:1];

Please note, calling setVisibleXRange() will zoom your chart. Not sure what's your use case
