Hey @RRoger, I think the problem is the name of the node you check against: you test against "Country Plot", but first this is the prettyfied name (I think the variable itself is named

country_plot

) and second this is a dataset, not a node. So either you change your hook into a dataset hook, or you check for something like

if node.name == "get_country_plot"

to get the node which creates this dataset. Does something like this work?
