This seems like a reasonable request although it would appear to require
further clarification as to whether this is possible under ODF v1.2 and what
this means for interoperability (if Excel is already doing this). Would appear
to either require:

(a) Setting a category child element in each X axis definition e.g. it is
possible to have this:

<chart:axis chart:dimension="x" chart:name="primary-x" chart:style-name="ch4"/>
   <chartooo:date-scale/>
   <chart:categories table:cell-range-address="Sheet1.A2:Sheet1.A5"/>
</chart:axis>
<chart:axis chart:dimension="x" chart:name="secondary-x"
chart:style-name="ch5"/>

... but having a separate chart:categories element for each X-axis would allow
specifying independent values.

(b) Allowing data series to be attached to X-axes e.g., it is possible to have
this for Y-axes:

<chart:series chart:attached-axis="primary-y" chart:style-name="ch9"
chart:values-cell-range-address="Sheet1.B2:Sheet1.B5"
chart:label-cell-address="Sheet1.B1:Sheet1.B1" chart:class="chart:bar">
   <chart:data-point chart:repeated="4"/>
</chart:series>
<chart:series chart:attached-axis="secondary-y" chart:style-name="ch10"
chart:values-cell-range-address="Sheet1.C2:Sheet1.C5"
chart:label-cell-address="Sheet1.C1:Sheet1.C1" chart:class="chart:bar">
   <chart:data-point chart:repeated="4"/>
</chart:series>

... which again allows separate ranges to be specified for the primary / second
axes. I agree it would be great if the scales could be set independently. It
would seem to be compatible with ODF v1.2 but this really needs to be
determined by an expert. Confirmed. Status set to NEW. Component set to Chart.
Platform set to All/All. Summary edited for clarity.
