Create a chart with javascript

KARIMLABIDI — Tue, 19 Jul 2022 15:01:18 GMT

Hello,

I would like to create a chart with chart Js and that's not easy! I would like to load a json from my AGE rest and after that,create a cumulative chart with the length of my polyline.

My code blocks when I try to load data,it gives me a error 'undefined (reading Map)'. I don't know what to do.

The data looks like this

Any help would very appreciated 🙂

Is miseservice an array? Too tough to tell from a screenshot, but sounds like that property is not an array you can map over
