Hi:
I am not sure what you mean. Do you mean a "leader line" from the plotted
point to the corresponding x-coordinate? If so, Line charts have the
possibility to add a "drop line" (as Excel calls them) which you can format
to a subtle leader (eg dotted light grey) by double-clicking it.
If you want to separate the x-axis coordinates more clearly to help the eye
discriminate between x-parameters, there is a not so commonly known trick (I
haven't tested this at lenght but it is available for column, bar and line
charts). Right-click the chart and choose Source data. Choose series and
define for the Category X-axis labels an extra (empty) column (Example: if
you have 1-2-3-4 in B2 - B5, then select A2-B5 as category x label range
(with A2-A5 empty, or possibly in A2 the name of yr x-parameter (e.g.
Distance)).
I hope this helps.

GL,
Henk

How do I get the x-axis labels closer to the axis? When I format the labels
I can modify how much they're offset, but even setting it to 0 doesn't really
improve it much. Failing that, is there a way to create a "leader line"
from the label to the spot on the axis to which it pertains?
