It seems that the error of exporting PDF for the first time is not large, and there will be obvious errors when exporting PDF again.

Any update on this?

It pretty much makes the addon unusable for lots of use cases, since it not only affects PDF exports, but also the convert to image functionality itself.

same problem here, I just discovered the plugin and is awesome

I'm having a very similar problem when exporting a pie chart. Here is the chart from the documentation as an example:

incomplete pie

I think it is connected to the animation that plays when the chart is first displayed. My guess is that the animation is not finished when the note is converted to a pdf, resulting in a chart that is incomplete. If an option is added to disable the animation it should solve the problem.

Welp I spend ages on a graph for school work and it's useless because of this. EDIT: you can use the "Create image from graph" as a workaround. However it looks awful and the lines are so thin you can't see it

I've fixed the issue. (kinda) This isn't a perfect solution but if you need a quick fix:

  1. Download the new main.js file.
  2. Go into settings > community plugins > click on the folder icon next to "Installed Plugins"
  3. Go into the obsidian-charts folder
  4. Replace the old main.js file with the newly downloaded one
  5. Restart obsidian and it should work!
