How and is it possible that, when signing the divisions on the abscissa, instead of numbers, there was the number Pi with the corresponding coefficients?
There is a coordinate system and a sinusoid constructed in MS Excel. The abscissa axis has a division value of 1. The values ​​for the graph are calculated using the Pi function from MS Excel. Can you tell me if it is possible to make the scale division price "Pi / 2" and the values ​​​​on the scale be signed: P / 2, P, 3P / 2, 2P?
Thank you.
