1) That's no stupid question. 
2) The answer is no, currently there is no analogon. The corresponding 
functions are not exported to Python at the moment.
They will be in version 0.2.0, which will be released, well, when it's done. 
Then the Python line will look something 
like 't.column(col).setPlotDesignation("X")'.

By default the next X column to the left from the Y column is used. But you 
can use the plot wizard to plot any combination of columns regardless of the 
plot designation. If you want to do it using Python, use something like
"layer.insertCurve(table, "col1", "col2", type=1)" as described here:
