Problems with horizontal area series

[Alexey I.]

1) I use series option "Color Each" and add points to this series with method "Add(X, Y, Color);". This ends with exception on draw.
I solve this problem by separating up data in several "single colored" series.

2) When scrolling series at runtime, element of series disappears, when part of this element moves out of the chart workarea.

Code: Select all

series.Add(0, top);
series.Add(value, top);
series.Add(value, bottom);
series.Add(0, bottom);

I think that it depends on inverted Y axis. After I changed code to this:

Code: Select all

series.Add(0, bottom);
series.Add(value, bottom);
series.Add(value, top);
series.Add(0, top);

this problem disappears, but Click and DoubleClick events of other series (Shape series) stop works.
Please tell me, how to add such elements correctly (when Y axis is inverted).

3) In horizontal area series often elements (in start of series), such as described in (2) looks incorrect.
When I use code

Code: Select all

series.Add(0, 200);
series.Add(100, 200);
series.Add(100, 300);
series.Add(0, 300);

I can see dislocated rectangle approximately in 4 - 104 X values.
This bug is very serios and need to be fixed immediately !

Hi Alexey,

1) I use series option "Color Each" and add points to this series with method "Add(X, Y, Color);". This ends with exception on draw.
I solve this problem by separating up data in several "single colored" series.

I haven't been able to reproduce this problem here. Could you please send us an example project we can run "as-is" to reproduce the problem here? You can post it at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup.

Regarding questions 2 and 3, could you also reproduce them in the example project as I don't understand the problems very well?

Thanks in advance.

Hi Narcis,
I can't send you my project, because NNTP protocol is closed.
Try this C# code:

			this.Controls.Add(this.tChart1);
			this.Name = "Form1";
			this.Text = "Form1";
			this.Load += new System.EventHandler(this.Form1_Load);
			this.ResumeLayout(false);

		}
		#endregion

		[STAThread]
		static void Main()

			Application.Run(new Form1());
		}

		private void Form1_Load(object sender, System.EventArgs e)
		{
			horizArea1.Add(0, 50, Color.Red);
			horizArea1.Add(100, 50, Color.Red);

			horizArea1.Add(90, 210, Color.Gray);

}

After run this application you can see "System.ArgumentOutOfRangeException".

Hi Alexey,

I've been able to reproduce it and the problem was inverted axis. This is a bug which has already been fixed for our next releases.
