Import method of chart fx failed

[User (Legacy)]

Hello,

I made a application which is able to produce a chart using a datas file.

For this issue, I'm using template files which have been created with the

designer. Sometimes, my application gives me the following error message :

Method Import of ChartFX failed

I can't locate where this error is coming from because sometimes it works

fine and sometimes not.

Any idea ?

Thanks,

Murielle
