I am working with Mohr circles and I want to draw a circle on my graphs using
a data point (x,y) values to make the circles. Now if I were using a
compass, I would set my compass point on the x-axis at the x-value and then
draw a circle with radius (y) around that point making certain that I
intercept the x-axis at distance (x + y), (x - y) and point (x,y). I am
trying to figure out if there is someway I can conveniently construct these
circles in excel rather than printing out the graph and then hand-drawing
them over the plotted data points.
