# Polar chart2

## Polar chart

(OP)
Hi Friends,
How to plot a polar chart using excel?
My data is like this
Angle     Value
63.5 deg   2000
90.2 deg   3800
118.5 deg  4472
151 deg    5510
149 deg    5710
147 deg    4000

Angle     Value
63.5 deg   2000
90.2 deg   3800
118.5 deg  4472
147 deg    4000
149 deg    5710
151 deg    5510

What happens at 0 degrees
and 180 degrees?

Remaining all the angles beyond the specified range the value is zero. (ie. from 0 to 63 deg and 152 to 360 deg)

generate the xy coordinates and plot it as an xy plot, or interpolate for every angle and plot as a radar plot.

Hi Greg,
Thank you very much for your reply. First part of the answer is OK (xy plot). Could you please briefly tell about the interpolation in radar plot. In fact I tried the radar plot with the above data. It is dividing the 360 deg with the number of data points. I don't know how to proceed.

### RE: Polar chart

Generate a column 1-360. Fill the next column with linearly interpolated values from your data. Plot it as a radar plot

Cheers
