Missing bars

[Olliver]

Hi,

I created a simple bar chart with one serie and 5 bars which have no x value. If e.g. the 3rd y value is zero, the 4th and 5th bar is missing.

Displaying 4 or 6 bars is correct; means all 4 or 6 bars are shown.

For reproducibility here an example:
Place a TeeChart on a WebForm and use this code for displaying the data:

Code: Select all

protected void Page_Load(object sender, EventArgs e)
{
    Steema.TeeChart.Styles.Series series1 = null;
    series1 = WebChart1.Chart.Series.Add(new Steema.TeeChart.Styles.Bar());
    series1.Title = "Test";
    series1.ShowInLegend = true;
    series1.Marks.Visible = false;

    series1.Add(99.1, "A");
    series1.Add(75.0, "B");
    series1.Add(0, "C");
    series1.Add(63.3, "D");
    series1.Add(50.0, "E");

}

Do you have an explanation, workaround or hotfix for this strange behaviour?

I'm using VS2008 with TeeChart v3.5.3317.17532 (30.1.2009)

Hi Olliver,

I found that this was broken with 30th January 2009 release. It worked fine with previous version. I'll send you an e-mail with the URL to download it. I've also added the defect to the bug list (TF02013809) to be fixed for next releases.

Hi Narcís,

thank you.

In the meanwhile I've uploaded two screenshots to your upload-server. (Missing bars.zip) You can skip them...

Hi Narcís,

I successfully downloaded an installed the TeeChart Version from your E-Mail Link. But the effect is the same. I can't see any difference in the behaviour TeeChart is drawing charts with 5 bars. It breaks after the first Zero value.

Hi Olliver,

Sorry, I didn't send the build I meant. I'm going to send you an e-mail with the link to download build 3.5.3274.30664. Anyway, it's quite strange as the version I sent you also works fine for me here. As you can see in 30th January build release notes, a similar issue (TF02013714) was fixed. I think this fix may have caused TF02013809 in that build. Could you please check if 19th December 2008 build solves the problem for you?

Thanks in advance.

Hi Narcís,

the Version from 19th December 2008 (v3.5.3274.30664) has a quite similar bug (There is missing the last (5th) bar if the first three are zero!).

The reason why I changed to the newest release was a bug displaying the Tooltips correctly, when TeeChart is embedded in WebParts.

So I deinstalled the latest version of TeeChart and started installing the following versions after each other (w/o deinstalling the previous ones):
v3.5.3105.20152 - 2008-07-03
v3.5.3188.18562 - 2008-09-23
v3.5.3274.30664 - 2008-12-19
v3.5.3317.17532 - 2008-01-30

Procedure:
- Close Visual Studio
- Install next Version of TeeChart
- Start Visual Studio and start the WebSite in Debugger-Mode
(because there is a TeeChart.dll.refresh file in the bin-Folder the actual Version is used)[/list]

I'm sorry, I was not able to reproduce the Tooltip-Error. But the "Missing bar"-Error occured in v3.5.3274.30664 (2008-12-19) and v3.5.3317.17532 (2008-01-30)

Now I'm using v3.5.3188.18562 (2008-09-23) and wait for your next release

Best regards,
Olliver

Hi Olliver,

Thanks for the information.

the Version from 19th December 2008 (v3.5.3274.30664) has a quite similar bug (There is missing the last (5th) bar if the first three are zero!).

I can reproduce the "Missing bar" bug (TF02013809) in a simple WinForms application dropping a TChart into a form, using default size and using this code:

Code: Select all

		public Form1()
		{
			InitializeComponent();
			InitializeChart();
		}

		private void InitializeChart()
		{
			Steema.TeeChart.Styles.Bar series1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);

			series1.Add(99.1, "A");
			series1.Add(75.0, "B");
			series1.Add(0, "C");
			series1.Add(63.3, "D");
			series1.Add(50.0, "E");
		}

Populating series using this code:

Code: Select all

			series1.Add(0, "A");
			series1.Add(0, "B");
			series1.Add(0, "C");
			series1.Add(63.3, "D");
			series1.Add(50.0, "E");

Only plots the first bar in the series . I'll update the information in the bug description to be investigated too.
