Is it possible to combine a plot of a function, example y=f(x) together
with
other chart data? One example is to plot a straight line or multiple
lines
together with x-y or bar charts.
I know I could simply generate the data and populate cells and then plot
this data together with the other data, but is there a way to do it
without
filling cells?
