Hello,
This is a problem for which there seem to be several solutions
online, but
not really. My question was about plotting a curve over the
histogram. All
the previous posts and messages talk about generating a *density
histogram*using (freq=F) and then plotting the density curve. However,
I find that
that seriously distorts my data and the plot becomes confounding to
the
viewer.
How does this ``distort'' your data? You are simply changing
the scale on the y-axis.
I was wondering if there's a way to do the following 2 things:
1) Plot both histogram and the overlying frequency curve in one plot
If you want to keep your histogram on the ``count'' scale,
just multiply your density curve by the constant by which
you would have divided the histogram values to change
counts into density values.
2) Plot multiple frequency curves in a single plot
?lines
I have been using the "hist" function for my job.
I'd appreciate if anyone could help me with the solution
cheers,
Rolf Turner
