jcl, c'mon!

The script is 3 lines, and it does not plot as expected (at least on my end).
Before posting here, I do the homework: the _plot.csv file contains all the correct values and zooming into an area reveals the correctly plotted values as well.

BUT the Total view doesn't show anything, as in the pic I attached.

Can you just spend 1 min and either confirm it or not?
