Hi,

Thanks for adding this new feature.

I allow users to change the legend position from a shortcut menu on the chart. If they change, say, from right to top, the PaletteOrientation doesn't change automatically like a standard legend does.

I achieve the legend position change by having separate chart and legend panels and reorganising them. I could switch the PaletteOrientation myself but I cannot see how to get from the Chart Legend (NLegend chartLegend) to the elements on it to achieve this (as they were added using chart.DisplayOnLegend = chartLegend). Is there a way to do this?

Thanks

Kevin

PS there is a typo in the property NAutoLegend.PaleteScalePosition (missing t)

Hi Kevin,

For an automatic legend you need to touch the palette orientation property of the NSeriesLegend for example:

someSeries.Legend.PaletteOrientation = PaletteOrientation.Horizontal;

Let us know if you meet any problems or have any questions.

Thanks for the typo tip Smile...

Thanks for the reply but you didn't answer my question. I know how to change the PaletteOrientation for a series Legend, but I asked if there was any way to get to the series legends from the chart legend.

Thanks

Kevin

Hi Kevin,

Currently there is no way to get the series that display on a legend, however you can easily loop through the chart/series in the control and check which ones display on that particular legend:

   List<NSeriesBase> seriesOnLegend = new List<NSeriesBase>();

   for (int i = 0; i < nChartControl1.Charts.Count; i++)
   {
    NChart chart = nChartControl1.Charts[i];

    for (int j = 0; j < chart.Series.Count; j++)
    {
     NSeriesBase series = chart.Series[j];

     NLegend curLegend = series.Legend.DisplayOnLegend;
     if (curLegend == null)
     {
      curLegend = chart.DisplayOnLegend;
     }

     if (curLegend == myLegend)
     {
      seriesOnLegend.Add(series);
     }
    }
   }

Hope this helps...
