How to get Axis Range in UWP chart?

The UWP Chart provides two important properties for managing axis ranges: ActualRange and VisibleRange. The ActualRange consistently holds the complete data range of the axis, while the VisibleRange dynamically reflects the currently displayed range, especially during zooming, panning, or scrolling interactions. This article will guide you on how to access both of these range types.

Step 1: To retrieve the VisibleRange of a ChartAxis, access its VisibleRange property. This can be done, within the LayoutUpdated event of the chart to get the current visible range. 

<chart:SfChart x:Name="chart" LayoutUpdated="chart_LayoutUpdated">
    <chart:SfChart.PrimaryAxis>
        <chart:CategoryAxis Interval="2" x:Name="primaryAxis" />
    </chart:SfChart.PrimaryAxis>
    . . .
</chart:SfChart>

private void chart_LayoutUpdated(object sender, EventArgs e)
{
    var visibleRange = primaryAxis.VisibleRange;
}

Step 2: To obtain the ActualRange of a ChartAxis, handle the ActualRangeChanged event. This event provides the ActualMinimum and ActualMaximum values in its event arguments, representing the start and end of the entire axis range.

<chart:SfChart x:Name="chart" >
    <chart:SfChart.PrimaryAxis>
        <chart:CategoryAxis Interval="2" x:Name="primary" ActualRangeChanged="primary_ActualRangeChanged"/>
    </chart:SfChart.PrimaryAxis>
    . . .
</chart:SfChart>

private void primary_ActualRangeChanged(object sender, ActualRangeChangedEventArgs e)
{
    var primaryActualMin = e.ActualMinimum;
    var primaryActualMax = e.ActualMaximum;
}
