Hi Experts,
Is there a way to get an existing point-series of a chart by name or ID (and check in the first place, if a series with that name does exist at all)?

I get the name / id within e.g. a mouse move event:
... ((NSeriesBase)hitTestResult.Object.ParentNode).Name;
... ((NSeriesBase)hitTestResult.Object.ParentNode).Id;

Now I want to remember just the name / id in case I have to change series properties later.
I am looking now for a way to retrieve the serie by name (or ID) something like:
if( _NevronChart.Chart[0].DoesSeriesExist(m_sNameOfSeries) {
NPointSeries series = _NevronChart.Chart[0].GetSeries(m_sNameOfSeries)....
}

Thanks for your help,
Joern

Hi Joern,

You can look for chart elements by their unique id - it will stay the same even if the document is serialized / deserialized:

        Guid m_LastClickedSeriesId;

            NChart chart = nChartControl1.Charts[0];

            NBarSeries bar1 = new NBarSeries();
            bar1.Values.Add(10);
            bar1.Values.Add(20);
            bar1.Values.Add(30);
            chart.Series.Add(bar1);

            NBarSeries bar2 = new NBarSeries();
            bar2.Values.Add(10);
            bar2.Values.Add(20);
            bar2.Values.Add(40);
            bar2.MultiBarMode = MultiBarMode.Clustered;
            chart.Series.Add(bar2);

            nChartControl1.MouseDown += new MouseEventHandler(nChartControl1_MouseDown);
            nChartControl1.Refresh();

        void nChartControl1_MouseDown(object sender, MouseEventArgs e)
        {
            NHitTestResult result = nChartControl1.HitTest(e.X, e.Y);

            if (result.ChartElement == ChartElement.DataPoint)
            {
                m_LastClickedSeriesId = result.Series.UniqueId;
            }
        }

        private void HighlightLastClickedBar()
        {
            NBarSeries series = nChartControl1.Document.GetElementFromUniqueId(m_LastClickedSeriesId) as NBarSeries;

            if (series != null)
            {
                series.FillStyle = new NColorFillStyle(Color.Red);
                nChartControl1.Refresh();
            }
        }

The above example shows how to store the unique id of the last clicked series and then to search / highlight.

Hope this helps - let us know if you meet any problems.
