I have a bunch of diagrams for a set of route segments, stored as PNG, PDF or SVG with a regular name (topic-segment-id.(png|pdf|svg) for example), representing a certain aspect (like crossing rate or and angle for ships at a segment (..see graphics, polar density plots).
I'm able to generate the images of the diagrams (including a subsequent image processing chain) with a name carrying the segment-ID. I can also create a point layer for the placement of the diagrams, with attributes for the filename and/or the segment-ID, at the map (..see map points 1 to 17 corresponding to the diagrams above) along the route.
How can I load and place the segment related images (the generated diagrams for example) at the addressed points/segments for the corresponding map under QGIS wit the print composer/ map layout tool. I want to have something like that:
PS: I use the statistic language R to create diagrams and the point layer (package sf) and QGIS to generate the maps.
