Adjust Resolution Bug With Data Values 0 < X < 1

I found a bug with adjust resolution on a bar chart. The chart has 2 data values. If they are both between 0 and 1, adjust resolution does not properly scale the values. I'm not sure if this is the modules fault or Google's fault. To see the problem, simply recreate the create, and use:

$chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][0][] = chart_mixed_axis_range_label(0, max(abs($value-one), abs($value-two)));
