Histogram in Bar

namespace NevronProve1
{
     public class NNevronProve1UC
     {
public double [] XValues;
public double [] X2Values;
public double [] Values;
public double [] Y2Values;
public double [] ZValues;
public double [] Z2Values;

chart.Enable3D = true;
nThinChartControl1.ImageExporter.SaveToFile (dir + fileName, new nSize (this.XDimPixel, this.YDimPixel), NResolution.ScreenResolution, new NJpegImageFormat ());
}
}
how to read the position (in pixels) x, y, z of each single bar, to pass to XYZValues methods?
Thank you very much.

Hi Ivano,

Please elaborate on the question - it is not clear what you want to achieve.

Good morning, by chart.bar I need to know the coordinates X , Y , Z of the bars , in pixels , to go to the properties ' of my .dll , to intercept the area of the bars with mouseover of Instant Developer . Thank you and I cordially greet Ivano Rigato

Yes, from jpg map would know the positions of pixels in histogram bars . The .jpg is then used within the Instant Developer to switch to the X , Y of the bars to trigger the event OnMouseOver . Thank you and I cordially greet Ivano Rigato

Hi Ivano,

The following code shows how to get an image map output from the control:

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

            bar.Values.Add(10);
            bar.InteractivityStyles.Add(0, new NInteractivityStyle("Bar0"));

            bar.Values.Add(20);
            bar.InteractivityStyles.Add(0, new NInteractivityStyle("Bar1"));

            bar.Values.Add(40);
            bar.InteractivityStyles.Add(0, new NInteractivityStyle("Bar2"));

            chart.Series.Add(bar);

            NSize dimensions = new NSize(nChartControl1.Width, nChartControl1.Height);
            NHtmlMapContext context = new NHtmlMapContext("Chart", "someImage.png", 1, dimensions, NResolution.ScreenResolution, string.Empty, ClientScript.JScript, ImageMapMode.XHTML, false);

            StringBuilder stringBuilder = new StringBuilder();
            StringWriter stringWriter = new StringWriter(stringBuilder);
            using (NChartHtmlImageMapView htmlMapView = new NChartHtmlImageMapView(nChartControl1.Document, dimensions, NResolution.ScreenResolution))
            {
                htmlMapView.WriteImageMap(context, stringWriter);
            }

            stringWriter.Flush();

            string result = stringBuilder.ToString();

In the resulting image you should regard only the areas with alt or title if you want to get the bars pixel coordinates. Hope this helps - let us know if you meet any problems.
