This writeup of a very interesting dedicated theater room installation features a polar map of the speaker (see p. 15, § 3.4). The owner of the system said it was done in Excel, but by someone else.
Does anyone here know Excel well enough to create a template that would allow one to make such a polar map using measurements taken at different angles in FuzzMeasure/Holm/etc. and exported to Excel?

Excel supports the so-called snowflake plot format, where the spokes of the snowflake represent different parameters and the radial distance on each spoke is the value for the particular parameter. It is easy to set up a pair of columns where Column 1 is the angle and Column 2 is the measured level. In the dialog box for the plot format assign Column 1 to be the Horizontal Category Axis Labels and Column 2 to be the Legend Entries. Took about a minute.
That's not a very good looking polar map. I have offered to do them on my software if supplied with the right data.
That is just a 3D plot viewed from above - it is easy to do, just play around a bit.
