How to limit number of categories in ChartView CategoricalAxis

[Chris]

We are trying to use a ChartView with a LinearAxis for the vertical axis and a CategoricalAxis for the horizontal axis. Our issue is that we can't find a way to limit the number of category items in the horizontal view of the ChartView. We'd like to have a max of 14 items in the view before requiring the user to scroll to see more category items, but as it stands now, the more items that are added to the ChartView, the smaller and smaller the items get until their labels overlap.

Is there a way to limit the view of the ChartView to a max of 14 items so that the user can scroll to the right to see more items?

Thanks!

Hello Chris,

The chart will plot a category slot for each distinct category in its data source. You cannot limit this without removing items from the data. Anyway, you can achieve your requirement using the chart's pan and zoom behavior. This way you can limit the visible area of the chart and scroll to see the rest of the data.

You can use the chart's HorizontalZoomRangeStart and HorizontalZoomRangeEnd to limit the viewport. Note that the properties work in relative units between 0 and 1.
