I think that this is the same problem as 0010692. What platform are you using (linux or Windows)?

Using CentOS 4.

Not sure this is the same, this one is JpGraphs the other one looks like the builtin stuff.

Interestingly I can't find any reference to the parameters used in the other slip.

I have also downloaded and build the MST fonts package. I then symbolically linked them into the default directory required by JpGraph as well. Still no joy.

Hopefully this is just a config issue as the JpGraph stuff is rendering, just having issues with the fonts. Maybe it's looking for a TTF font I don't have? But I don't have a clue where to look.

Here is what I have installed after the MST core fonts setup.

/usr/share/fonts/truetype/webdings.ttf
/usr/share/fonts/truetype/trebucit.ttf
/usr/share/fonts/truetype/comicbd.ttf

Any ideia of my issue??

My graphs don´t show anything. My version of php is 5.1.6, my gd is enabled, my jpgraph is instaled, any messages of error.

And now ??

Problem is the query to the database, the generic category for projects was forgotten.
Within MantisGraph/core/graph.php around line 756
Query should be

$query = "SELECT id, name
FROM $t_cat_table
WHERE $specific_where or project_id = 0
ORDER BY name";

I have the same problem. It worked OK with other versions of JPGraph but with the last one doesn't work.

No it's not the same problem with: 0010692

Here the same issue but a little bit different:

These graphs working fine:
[ Per state ] [ Per priority ] [ Per severity ] [ Per resolution ]

Same error only here:
[ Per category ]

just for bug note completions sake, what version of jpgraph and mantis are you guys using?

MantisBT Version
1.2.1

JPG_VERSION
3.0.7

Strange situation. Looks it's depends on the project.
In some project it's working well and in some other it's not working.
i can't find any relations between the errors, we use global categories so that was the same always.
