Description Kevin Cox 2012-10-22 23:26:32 UTC

Currently there is no way to have formatted math equations in the titles of a chart.  This would be especially useful for the units.  (ex: m/s^2)  This would really increase the appearance professionalism in the resulting chart.

It would be nice, although there are problems like bug 39052. Maybe if this is possible it would be a possible workaround to 39052...

Comment 2 Kevin Cox 2012-12-13 20:21:22 UTC

Yes, this is definitely related to bug 39052.  I say this because you can use cells for labeling data series which prevent those from having rich text.  And I can only assume that that transfers to the other titles in the charts.

I can confirm this in 4.0.2

Kevin, do you mean extended math equation functionality to have a LaTEX-type level of complexity, or simply usual text formatting capabilities like italic, subscript and superscript?

If this is only about the second option, this bug is a duplicate of bug 39052.

In 4.0.2 (not sure about previous versions), it is possible to insert special characters - like mathematical operators and greek alphabet letters - by using "Insert -> Special characters" when editing the text box.

I was think about maths.  A common use case is powers and subscripts for the units which would be solved by bug 39052 but you often need funkier units and things in the title (often when linearizing an equation and you get weird things).

I would say this is also a work around but it would be nice to have the full power of a formula.

Right, fair enough, I get it now.
So this is definitely a different bug.

Cheers for the quick reply, Kevin!
