Here’s my problem: out of the box, it’s easy to zoom/pan into some weirdness.
I can correct for this if I have the highest, and lowest y value within the currently visible range. Not the yValues labeled on the yAxis, but instead the actual values on the chart.
Basically I want to find the lowest, and highest y values in the visible range and set the actual scope of the yaxis to that so I can bring the chart back to earth.
[_chart.yAxis setRangeWithMinimum:lowest_low andMaximum:highest_high];
Is this info stored anywhere? Or any ideas how it should be derived?
