Hello,
I have problem how to draw a curve onto a polar chart that is based on degree
and its values.
Also after the curve is plotted, then I like to extract the curve equation.
Thanks

Andy Pope has a polar plot add-in at http://www.andypope.info/charts/polarplot3.htm. I've not used it, but expect it's great.
You're not going to be able to regress that with a polynomial. Maybe Fourier regression -- it has the shape of a pulse (after you make it symmetric).
Entia non sunt multiplicanda sine necessitate
There's a Fourier expansion of your function at https://app.box.com/s/ereqysafe9cshbpuu5fg
Hi shg,
I download this add-in before, I have not spend a lot time to try.
But I am looking for VBA to draw the curve and polar chart, even
if it can also create the text for the angles.
The table will be come from external text file that will be inserted
the specified cell to automate the report only using few keys.
Maybe the point from table in degree and value (consider
it is the length from 0,0) may need to convert to X,Y so that
it can plot the curve. Same true for the polar chart.
Is there an equation to draw the polar chart, 1/4 circle, text in degree
placed on the chart liked the sample?
Thanks
I will try this. thanks
You're welcome.
