Hello, on my normal page the chart is appearing even if there is no data on that, and on the pdf he is not appearing... What should be?

Hello Vinicius,

Could you provide a minimal working OML with this behavior?
So we can test it?

Cheers,
Eduardo Jauch

EDIT

HA! J. was direct to the point... It seems that converting to PDF a page with a Chart is not "ordinary". :)
