Does the chart know you have X data? Go to Chart menu Source Data Series
tab. Is there anything in the box for Category Labels? This should be a link
to the X values range in the worksheet, just as the Y Values box links to
the Y data.

However, I think a more fundamental problem is that you are not using the
right chart type. Use an XY chart, which treats numerical data as numbers,
not as text labels. With an XY chart, you can double click on the X axis to
get the kind of scale and spacing you describe.

I have created two line images on a Line Chart using several data points.
Now I would like to have an x axis that shows a marker for every 1/2 hour.
Example: .5 1.0 1.5 2.0 2.5 3.0 and so on for up to 5.0 to
represent hours. I created the data for these time points that coorespond
to
my data for line images but do not know how to show them in my x axis as
markers. Any idea? My x axis shows nothing? Y axis is fine. I have
data
scale markers there.
