How can I create a time-date graph such that the values are plotted at the
correct time positions within the date range rather than all on the date
vertical axis?

Choose Chart type XY (Scatter) instead of Line. Line has only the
options of Category (which won't distribute the values properly) and
Time-scale (which, for some bizarre reason, Microsoft limits to whole
days only - no times available).

Time-scale can sometimes be useful as a sort of Interval scale for Line
and Area chart types, but because it only does integers, not fractions,
it's no good to you here. Only a proper interval/interval chart type
will do.

Also, make sure the X values are proper "date plus time" format all in
one cell. A date in one cell and a time in another won't work.

Many thanks Del. That seems to work fine after a little tinkering with both
of the axes.

Del -

It's still a category axis. I think the magic done under the covers simply
skips some categories in between to plot uneven intervals of whole numbers.
So we're still stuck with days only.

What you could do if you like the way the date axis is formatted (I know I
do), is to make a line chart with a hidden series (no markers or lines) to
control the axis, then add your real data as XY series, using real dates and
times for the X values. These somehow are allowed to display in between
categories and show times other than midnight on the days along the axis.
This combination Line-XY approach also helps to display data where the
series don't have points on the same days. Line chart series are tied to the
dates for the first series, but XY series are independent of each other.

Jon,
This is just what I need. I've had a go, but am failing miserably so far.
I've been looking at your pages for an example but no joy so far. If there is
a specific example on your site could you please point me at it.
Thanks

Too bad you deleted the post you were replying to.

You can try changing the axis to text format

Even better, use an XY chart. You need the full date and time values in
the cells containing the X values.
