calcMinMaxY method
Calc minimum and maximum y-values over all DataSets. Tell DataSets to recalculate their min and max y-values, this is only needed for autoScaleMinMax.
@param fromX the x-value to start the calculation from @param toX the x-value to which the calculation should be performed
Implementation
void calcMinMaxY(double fromX, double toX) {
for (T set in _dataSets) {
set.calcMinMaxY(fromX, toX);
}
// apply the data
calcMinMax1();
}
