I also have scheduled exports running weekly that email the spreadsheets and downloadable reports on the site with user set parameters. all working with no issues. I will certainly be looking at the J3 version when it comes to upgrading my sites.
I contacted Chris with a question regarding plots with no data. Within 12 hours I had a reply and an updated component that totally solved the problem. You don't get that level of response from many of the "big players"!
Keep up the good work Chris, and, for anybody who requires charts / graphs on their site - look no further!
Keep up the good work!
