How do I set up the RangeSelection to do this please?

For a standard horizontal x-axis, I use:

NRangeSelection rangeSelection = new NRangeSelection
{
HorizontalAscendingZoom = true,
ZoomOutResetsAxis = true,
HorizontalAxisId = (int) StandardAxis.PrimaryX,
VerticalAxisId = (int) StandardAxis.PrimaryY
};
chart.RangeSelections.Add(rangeSelection);

If I set
chart.SetPredefinedChartStyle(PredefinedChartStyle.HorizontalLeft);

What do I change the rangeSelection to? I've tried various permutations, but none of them allow me to zoom. I get a red rectangle dragging the selection area in all directions.

Thanks

Hi Kevin,

Apologies for the delayed response. You need to touch the HorizontalAscendingZoom and VerticalAscendingZoom properties of the range selection to make this work. For example:

NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];

NRangeSelection rangeSelection = new NRangeSelection();

rangeSelection.HorizontalAscendingZoom = true;
rangeSelection.VerticalAscendingZoom = true;

chart.RangeSelections.Add(rangeSelection);

NBarSeries bar = new NBarSeries();

bar.Values.Add(10);
bar.Values.Add(20);
bar.Values.Add(30);

chart.Series.Add(bar);

chart.SetPredefinedChartStyle(PredefinedChartStyle.HorizontalLeft);

nChartControl1.Controller.Tools.Add(new NPanelSelectorTool());
nChartControl1.Controller.Tools.Add(new NDataZoomTool());

Hope this helps – let us know if you meet any problems or have any questions.

Thanks, that works as expected.

What is the correct combination for PredefinedChartStyle.HorizontalRight please?
No combination of the two properties seems to work.

Thanks

Please ignore my previous message. I've worked it out!
