I am having the same problem with a bar chart.  I have W2003 Server, II6.0 with ASP.net 1.1, Parent Path turned on. 

Hello Steve,

Have you tried the fix that we gave before to the other user?

If that does not solve the problem, can you give us FTP access to your site so we can investigate this? If yes, please post the FTP connection details private, and an URL to the page with the problem.

Regards,

The server this is on is on a university intranet, so I can't get you access.  Can you send me the link to the Knowledgebase article so I can review.  Also, will this fix work for a bar chart?

Thanks,

Hello,

Unfortunately, without FTP access there is not much we can do about this issue.

The fix that worked before for the other users was this:

open the file /includes/MXCharts/MX_PieChart.class.aspx and go to line 127-128 and

Change:

Dim startAngle As Double = -90.0
Dim sweepAngle As Double

To:

Dim startAngle As Single = -90.0
Dim sweepAngle As Single

Upload it to the test server and give it a test.

If this does not work, try to call this page in browser:

<your site root>/includes/MXCharts/MX_GenerateChartImage.aspx

and tell us the output you get.

Florin

I tried the changes to lines 127-128 in the MX_PieChart.class.aspx file.  I still get this error message:

MX Dynamic Charts Error: A non 200 Status page have been received when calling for image component ('http://localhost/includes/MXCharts/MX_GenerateChartImage.aspx')
Status=500

Here is the output from running

Hello,

It seems that you don't have permissions to access/execute this file. Please try to give permissions to the NETWORK_SERVICE user to this file, and make another test.

Can you duplicate this issue on a server where you can give us FTP access? I think that could speed up the debug process.

Thanks, that did it.  A question, though. 

What users (ie, NETWORK_SERVICE, NETWORK, IUSR_MACHINENAME, IWAM_MACHINENAME, USERS, etc) should have what type of permission (READ, WRITE, EXECUTE, FULL CONTROL) for the page.  

And,  the same question applies for the includes/MXCHART and the includes/MXCHART/ChartImages folders?

Thanks

Hello,

I think IUSR_macchinename and IWAM_machinename are included in NETWORK_SERVICE account. So you should grant permissions (read/write/execute) for NETWORK_SERVICE and then make some tests.

Cool.  Thanks for your help.
