[solved] gb.chart

Post by Got2BeFree » Wednesday 17th May 2017 3:57am

I need to create a graph using data I'm collecting using my RPi. It seems there is very few examples and even less information about the gb.chart component. I can show one line, but I would like to display multiple lines on the chart. Anyone know if this is possible?

I thought I'd have a go at this and got it working with one line then re-read your post and noticed you wanted 2 lines! :o So I had another look and found 'Chart.CountDataSets' which seems to be what you are looking for. I started with some code from here https://novatocodegambas.blogspot.com/2 ... ficas.html and came up with the attached program.

I hope it helps.

Thanks! The .CountDataSets was the missing link! Either I overlooked it or thought it was for some other function. Now on to database mining...
