Can I adapt the visble data in the chart to the Yaxis when I drag the chart across the x axis?
In the actual example I can drag the chart across the X Axis, but the chart doesnt adapted to the Y Axes. The y min, and the y max options are the same and calculate for all the chart.

You could get the min and max values and set the plot like that:
