How to make FusionChartsSave.py work with python2.4 and PIL-1.1.6 Module?

[zxo102]

Hi there,

I downloaded the FusionChartsSave.py provided by the fusioncharts team in this forum. I would like to run it with python2.4 and PIL-1.1.6.  I tested it against fusioncharts3.0.7.  It does return an image for me to save but the image has nothing to do with curves and messed up with different junk colors. I also tested the script with the trial version of fusioncharts3.1. Everything is fine but there is nothing to be returned for me to save except web page displaying error.

I did not get any error when I run this script: FusionChartsSave.py under python2.4 and PIL-1.1.6. Anybody knows what is wrong with it?

Thanks for your help in advance.

Hi,

 

 

 

The exported data in 3.1.x is very much different from the export data in 3.0.7.

 

 

 

For this the handler needs to be modified.

 

 

 

We will work on this and post on the forum again ... someday
