If you, for example, on a LineChartView set leftAxis.axisMinimum to 0, then the line itself will be clipped at 0 instead of being full width. Setting clipValuesToContentEnabled to true doesn't fix this, nor does altering the minOffset of the view. And there is no easy way that I can think of to offset axisMinimum to compensate for lineWidth (since the width is in screen points which will not translate neatly to an axis value).
