jc,
I left the plot statement off. Sorry.
If you wish to plot upvol, add the following line
upvol
if you wish to plot dnvol, add the following line
dnvol
if you wish to plot both, add following lines
upvol;
dnvol
If you plot both and wish to change the colors, put them on a plot. Then
click on one or the other and change the color.
I tested the plot adding the above and it works.
Let me know if you have troubles.
Adding lines like the above is the equiv of a plot statement.
