apricimo Posted February 2, 2011 Share Posted February 2, 2011 Hello, Lets say I have an equation y=mx^2. If I plot this equation in excel and then set the x-axis to plot in log is the same thing as y=m*log(x^2)? Having difficulty in trying to discern what the log plot actually is doing.

Fuzzwood Posted February 2, 2011 Share Posted February 2, 2011 No, you only transform the scale in a, well, logarithmic scale. First mark will range from 1 to 10 (but also logarithmic in between), 2nd mark from 10 to 100, etc. It does not do anything with your function itself.

The calculation has some difference. y=mx2 log y = log m + 2 log x axis Y ; log scale y axis X; log scale x you can obtain m value from the intercept. To obtain m value from data, y var X2 plot is more useful. At this time we can obtain m value by using list square method of zero point intercept.
