Re: [Image_Graph] Empty graphs

No it's not possible in the current version(s), however it's an interesting point, seing that dynamic data isn't 'always there'. I'm not sure if writing 'no data' would be the best idea in all cases, but maybe implement some kind of 'no-data'-handler, which could either print out no-data, show a picture of Queen Elizabeth, or what-ever. So basically, I agree that we should implement some kind of method for handling this case. I acually ran into it myself with the project I use Image_Graph on, what I did was basically to scale the axis so they still made sense, but there were just no graph visible.

Hi Jesper (et al), Sorry to bother you again, but I've got one last question regarding Image_Graph. Is it possible to produce a graph or message saying "no data" when no data is passed to the graph?

For instance, when I try and create a Pie chart, it comes up with the following error: Notice: Undefined variable: totalY in C:\www\pear\pear\Image\Graph\Plot\Pie.php on line 140 Thanks James
