Hi there, I'm trying to make my charts in webviewer instead of canvas. Starting to learn, I came to chart maker extension. When I build a list like this, it works: [01] But when I try to make the list out of data, my block doesn't work: [02] I get this message: Bad arguments to append to li…

These blocks will return a chart: [image] [image] global n = [ [5,10],[6,12],[7,14],......,[100,200] ]
