Variables: a graph variable's data set applies its CSV as graph.setData does

Browse Source 
Choosing a data set gave a graph variable's CSV to the graph without the
two steps graph.setData takes after new data: rows with neither a label
nor a value were kept and drawn as empty slots, and a right-axis series
the new data no longer had stayed assigned, so a series added by a later
row started on the right axis. The data set now goes through the same
steps.
