How to Edit a Vector Image (in 2026)
Suppose you've created a plot in JASP or jamovi and you wish to later it in some way that's not supported by JASP or jamovi. For example, suppose you want to increase the blank space that separates the legend from the rest of the plot, or thicken the outline of the plotting area, or combine multiple plots into one figure.
If you want to accomplish this using a simple tool that's similar to MS PowerPoint, use LibreOffice Draw.
In JASP (or jamovi) save the plot as a PDF image.
Open a blank LibreOffice Draw file.
In LibreOffice Draw, select file, open, and then specify the particular PDF image file you want to edit. The result will be an editable PDF.
Warning: If you attempt a different method--such as right-clicking the PDF and selecting 'open with' LibreOffice Draw, or pasting the PDF file into Draw, or using 'insert' - 'image'--you may end up with an image that's either not editable or not easily editable.
If you want to get multiple plots into the same Draw file, there are some initial hoops to jump through. Follow the steps above to get the one of the PDFs into one Draw file. Save and close that Draw file. Open a new Draw file and follow the above steps to get the a second PDF into a second Draw file. Keep the second Draw file open, and re-open the first Draw file. In the second Draw file, right-click and copy the the page in the 'Pages' pane. In the first Draw file paste the copied page into the 'Pages' pane. In the first Draw file, there will now be two pages, one containing each PDF image. The second page can be closed and discarded. In the still-open first Draw file, select the second page, copy the contents (using ctrl A, for example) and paste them onto the first page. You now have two PDF images on a single Draw page.
Another alternative is to use a more complex tool: Inkscape.
In JASP or jamovi (or whatever stats app you're using), export the plot as a pdf file. Because the pdf image format is vector-based, there's no danger of losing image quality due to pixelation. At this time, I do not recommend exporting as an svg: Despite svg being Inkscape's native drawing format, experience shows that the svg standard is handled inconsistently across various software applications. I find that the editing procedure can end up being simpler and more intuitive when working with a pdf.
Use Inkscape to open the pdf, and be sure to enable font-substitution while doing so. Once the pdf is open in Inkscape you can click, drag, and change various elements of the image. (Tip: To select text to edit, you have to double-click rather than single-click it.)
