Hello,

When I try to change the web chart style from any kind of style to Histogram, i get error "Index was outside the bounds of the array",
you also can download the sample project from

This seems to work fine with the lastest maintenance release, e.g.

Code: Select all

    public Form3()
    {
      InitializeComponent();
      InitializeChart();
    }

    private Steema.TeeChart.Styles.Points series;
    private Steema.TeeChart.TChart tChart1; 

    private void InitializeChart()
    {
      tChart1 = new Steema.TeeChart.TChart();
      tChart1.Dock = DockStyle.Fill;
      this.Controls.Add(tChart1);

      tChart1.Series.Add(series = new Points());
      series.FillSampleValues();

      tChart1.DoubleClick+=new EventHandler(tChart1_DoubleClick);
    }

    void tChart1_DoubleClick(object sender, EventArgs e)
    {
      Series series = tChart1[0];
      Steema.TeeChart.Styles.Series.ChangeType(ref series, typeof(Histogram));
    }

Why don't you try running the code I sent in a webchart on a webform? It should work in exactly the same way.

Dear Sir,

Is different, because only web will involved GetHTMLMap method
I think i put the wrong title, after checking the Exception.

Histogram error when trying to use SeriesHotspot to generate the e.PointPolygon.Attributes

Anyway, Please download the sample project to test it.

Thank & Best Regard

Dear Sir,

Look at the Exception... confirm that histogram got error on CalcXPos methods.

Steema.TeeChart.Styles.Series.CalcXPos(Int32 index) +43
Steema.TeeChart.Styles.Histogram.CalcRectangle(Int32 valueIndex) +214
Steema.TeeChart.Styles.Histogram.DrawValue(Int32 valueIndex) +88
Steema.TeeChart.Styles.Histogram.GetBounds(Int32 index, PolygonStyle& p) +36
Steema.TeeChart.Styles.MapRegion.GetPolygons(Series s) +376
Steema.TeeChart.Styles.MapRegion..ctor(SeriesHotspot h) +219
Steema.TeeChart.Tools.SeriesHotspot.GetMap(MarksStyles style) +47
Steema.TeeChart.Tools.SeriesHotspot.GenerateMap() +27

Thank & Best Regard

I see. I'm sorry, I think the title of this thread put me on the wrong track.

Histogram error when trying to use SeriesHotspot to generate the e.PointPolygon.Attributes

That would have been better

Anyhow, I've been able to reproduce the problem and have added it to our tracking database with reference TF02013326. This defect has already been fixed for the next maintenance release due out next month.

[Eric]

Dear Sir,

Oh, good to heard that problem has been solved.
Anyway, do you mind to send me the update dll as soon as possible?
Because we're running the demo in my customer server now, we worry this error ocurs at when they choose this chart style


Thank & Best Regard

Hello Eric,

the person who prepares the maintenance releases is on vacation period. But if you let me know which VS.NET version are you using I can prepare the dll and send it to you directly through mail.

[Eric]

Thank & Best regard
Eric

[Pep]
