zoomToSingleAxis method
Change the zoom level of an appropriate axis.
Here, you need to pass axis, zoom factor, zoom position of the zoom level that needs to be modified.
Implementation
void zoomToSingleAxis(
ChartAxis axis, double zoomPosition, double zoomFactor) {
_stateProperties.canSetRangeController = true;
final ChartAxisRenderer? axisRenderer = findExistingAxisRenderer(
axis, _stateProperties.chartAxis.axisRenderersCollection);
final ChartAxisRendererDetails axisDetails =
AxisHelper.getAxisRendererDetails(axisRenderer!);
// ignore: unnecessary_null_comparison
if (axisRenderer != null) {
axisDetails.zoomFactor = zoomFactor;
axisDetails.zoomPosition = zoomPosition;
_stateProperties.zoomPanBehaviorRenderer._zoomingBehaviorDetails
.createZoomState();
}
}
