Chart bars disappear when loading file

Hi.

I have a Calc file with some data and have created a chart out of it. When all it’s looking like I want to, I save and quit Calc… Next time I open up my file, the Chart’s bars are gone, as it was missing data, but that’s not the case.
I can see titles, legend and so on, but the actual bars aren’t there anymore. What gives?

Thanks

Nevermind; changed table layout to better handle data and it’s working fine now.
