there are still issues that don't work "visiblemaximum" when clicking the legend

Question

Hi,I'm working with StackedColumnSeries.

I have set visiblemaximum CategoryAxis of xAxis to control the visible range and chart can be scrollable with panning.

But when the user clicks on one of the legend to filter a series, the visiblemaximum that I have set does not get applied to the label and zooming.It seems that the cause is that xxxZoomFactor value will be the default value. (eg.currentZoomFactor:1.0)

Here is small sample code.

You can reproduce this issue by tapping the legend.

             SfCartesianChart(
              legend: Legend(isVisible: true),
              primaryXAxis: CategoryAxis(
                visibleMaximum: 2,
              ),
              series: >[
                StackedColumnSeries(
                    dataSource: [1, 2, 3, 4, 5, 6],
                    xValueMapper: (int data, _) => data,
                    yValueMapper: (int data, _) => data),
                StackedColumnSeries(
                    dataSource: [1, 2, 3, 4, 5, 6],
                    xValueMapper: (int data, _) => data,
                    yValueMapper: (int data, _) => data),
              ],
            ),

and I've found same issue in the forum.

I think this issue still remains in the latest version.

Is there a way to solve this issue?

Thank you.
