In the past, I have used the JFree Charts module to do this.  This module will generate charts in your Mendix app and create a PNG of these charts.  The PNG can then be used in a document template.  This module has not been updated for a while, but you could try it out:  https://marketplace.mendix.com/link/component/3011  You will need to update it to Mendix 9.

You can do this export manually, by preparing the data that you want to export to pdf similar to how you’re preparing it to be displayed on the chart. After that, you will need to create a document template, and design how the pdf will look like. Then create a microflow that prepares the data and create a filedocument object, and thenpass the prepared data and the filedocument object to the document template (generation activity) to generate the pdf. Lastly, you’ll need to download the filedocument object.

This widget lets developers generate PDF files using standard Mendix components.
The author provides a video instruction.
But not sure if it can run on version 9.
