I tried the solution and it's fine for data easily converted to a line
graph. I don't see how it can work with variable x data you often use for a
scatter plot. For the simple graph described, you can use a line graph and it
will be okay. But what if the original X data was something like 1, 1.2, 1.8,
4, 4.1 that you would like to see on a linear scale for the first graph.

Of course an obvious solution is to just use a set of text boxes, klugy but
workable I suppose.

Did I miss something I can do to use the suggested approach for a scatter
plot?
