calcMinMax method
Calculates the y-min and y-max value and the y-delta and x-delta value
Implementation
@override
void calcMinMax() {
if (_fitBars) {
xAxis?.calculate(getBarData()!.xMin - getBarData()!.barWidth / 2.0,
getBarData()!.xMax + getBarData()!.barWidth / 2.0);
} else {
xAxis?.calculate(getBarData()!.xMin, getBarData()!.xMax);
}
// calculate axis range (min / max) according to provided data
axisLeft?.calculate(getBarData()!.getYMin2(AxisDependency.left),
getBarData()!.getYMax2(AxisDependency.left));
axisRight?.calculate(getBarData()!.getYMin2(AxisDependency.right),
getBarData()!.getYMax2(AxisDependency.right));
}
