setGranularity method
Set a minimum interval for the axis when zooming in. The axis is not allowed to go below that limit. This can be used to avoid label duplicating when zooming in.
@param granularity
Implementation
void setGranularity(double granularity) {
_granularity = granularity;
// set this to true if it was disabled, as it makes no sense to call this method with granularity disabled
_granularityEnabled = true;
}
