If models are linked, you can easily import charts from one model into another, just like you can import variables.
Click on the link icon 🔗 next to the model name at the top left of the screen.
Select the model you want to import from.
You'll see a list of charts that you can import from the other model. Select a chart to import it.
The imported chart will appear alongside your other charts, the only difference being its title is Blue.
Note that if you are giving people access to only the model that imports charts, they will not be able to view the charts properly UNLESS you give them access to the underlying variables/data that the chart leverages. You can do this either by:
1/ Importing the variables/data that the chart utilizes, into the model you're sharing with them.
