visiblemaximum does not work when legend click

[Jaehwi Kim]

Hi, 

I'm working with StackedColumnSeries.

I have set visiblemaximum of of chart's x-axis so that if the data's length is more than 8, the chart would be scrollable to see more. 

zoomPanBehavior: ZoomPanBehavior(enablePanning: true,),
plotAreaBorderWidth: 0,
primaryXAxis: CategoryAxis(
  axisLine: AxisLine(width: 0),
  majorGridLines: MajorGridLines(width: 0),
  majorTickLines: MajorTickLines(size: 0),
  visibleMaximum: data_first.getData().length > 8 ? 8 : data_first.getData().length.toDouble(),
),

Everything works fine 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. (even though correct number of day gets shows correctly)

One thing I noticed was that this only occurs when the user have not scrolled the chart yet - if the user scrolled the chart to see other x-axis value, the legend filtering would correctly show wanted labels and zooming.

Here are screenshots of the chart:

- The chart user sees when none of the legend is filtered

- The label and zooming (also scrolling) is not applied when the user filters 'Generation' legend

- However if the user have scrolled the chart, filtering legend correctly displays the chart

Thank you.
