The LoglistPlot function plot the vertical axis in log scale and the
horizontal axis in normal scale. I need to do the opposite, namely, plot
the vertical axis in normal scale and the horizontal axis in log scale. I
checked in several books on Mathematica but could not get an answer.
I was also trying to do nonlinearfitting to the following group of data:
{0.5, 0.001}, {0.15, 0.005}, {0.1, 0.01}, {0.01, 0.1}, {0.001, 0.5}
The function
1-1/(1+0.00065/x)
produces a curve (use LogPlot[1-1/(1+0.00065/x), {x, 0.001,1 }) that seems
to fit the data. However, when I used NonLinearFit with this function, I
got the message that the function does not match a real number when
x=0.001.
Could someone help me on these two problems? Thanks a lot!
