<chart:SfChart.PrimaryAxis>
<chart:NumericalAxis />
</chart:SfChart.PrimaryAxis>
<chart:SfChart.SecondaryAxis>
<chart:NumericalAxis/>
</chart:SfChart.SecondaryAxis>
</chart:SfChart>
C#
public class ViewModel : INotifyPropertyChanged
{
…….
private ChartSeriesCollection seriesCollection;
public ChartSeriesCollection SeriesCollection
{
get { return seriesCollection; }
set
{
seriesCollection = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("SeriesCollection"));
}
}
public ViewModel()
{
SeriesCollection = new ChartSeriesCollection();
ColumnSeries columnSeries = new ColumnSeries()
{
ItemsSource = ColumnData,
XBindingPath = "XValue",
YBindingPath = "YValue"
};
SeriesCollection.Add(columnSeries);
LineSeries lineSeries = new LineSeries()
{
ItemsSource = LineData,
XBindingPath = "XValue",
