I am trying to create a figure from multiple vector-graphics plots from Matlab. As I will be updating the plots continuously I want to link to the files. When I link to my vector-graphics inkscape seems to convert them into raster? Why? Any way around this?

I'm not seeing a bug report for this exact issue, but there have been some issues linking svgs.

I'd try asking the developers on the chat: https://chat.inkscape.org/channel/inkscape_user
