Center of mass of points in log scale chart

Question

I would like to know what is the way to find the center of mass of some scattered points in a 2D plane where scales are logarithmic?

Is it safe to first convert them to normal scale and then compute X_mean and Y_mean and then convert that to log scale?

In principle, you don't "convert" the coordinates to normal scale, you just read the values using the tick marks, and they are already what you need.

$$\frac{1+2+100}3,\frac{1+10+100}3.$$

The red point shouldn't be somewhere in the middle of the triangle? – mahmood Mar 01 '21 at 14:15
