I'm using R to create some plots that refer to specific values of some point in QGIS. Each plot is saved into a directory and for each point in QGIS I added a column with the path to the file.
I know 2 different method to display these plots in QGIS:
- using the Action tool (Open file)
- using the Field tab of the Properties menu of the layer changing the Widget from Modify value to Photo
What if I have to do tons of plots or if I have a large point dataset? Is there a way to add automatically the path to the file in the attribute table? I tried to use the field calculator but I cannot figure out the problem.
Thanks to all
BTW: QGIS 2.1.0 master on Debian 7.3
