Hi there
I have a bunch of data which I'm trying to plot in a 3D plot.
Background - it's impedance measurements of a loudspeaker, measured at
different input voltages. I have:
voltage = [0.1 0.4 0.7 1.0];
f = a vector of frequencies (from 1.4 Hz to 20000 Hz ... I have a
total of 27000 data points in this vector)
m = a matrix of magnitude values, dimension matches frequency f and
voltage.
The frequency axis should be plotted on a logarithmic plot. Otherwise
I get the strangest looking plot (basically just a dashed line with
the axes - no graphs).
I solved this by plotting:
plot3d(voltage,log10(f),m',alpha=35,theta=45,flag=[2,2,3]);
When I plot a 2D plot, I can simply write something like
a.log_flags = "nln";
... But what should I do in a 3D plot ???
??? The same. each character of "nln" means "*n*ormal" or
"*l*ogarithmic", the first char for x, the second for y, the third for z.
So, unless i did not catch what you mean, just assign to a.log_flags the
n|l modes that you want.
