multiple color legends on the same image<BR></FONT><BR></DIV>
<DIV></DIV>Thanks for the info, but I hope folks don't mind if I ask a few
more questions to clarify this procedure. I've never used calculator before
and it seems hard to find any tutorials on this particular topic. However, I'd
like to just clarify exactly what I'm trying to do so that I'm not asking the
wrong question. <BR><BR>I'm applying paraview to overlay a functional brain
activation over a template I've specified. The brain map has both positive and
negative values and when I apply a contour filter to this object, I can
specify a range to show only some of the positive values, compute its
gradients and devise an appropriate legend. When I create a new contour filter
to show the negative ranges with the hope of showing another color legend that
reflects negative activation, this is where I run into the problem of my first
color legend immediately changing to whatever I now specify. Having said all
that, how does one duplicate datasets in calculator with the ability to
specify only part of the range of values so that only the negative activations
are shown? <BR><BR>Again thanks for the help and if there is a good tutorial
one could recommend to me so I could get some better grounding with this
program, I would be most grateful. Thanks!<BR><BR>-Dae Il<BR><BR>

coloring for all variables of the same name consistent. This is done
to prevent misleading coloring when showing data from different parts in the
pipeline or different data sets or different views. If you want to
break out of that behavior, you have to rename the field on one of the data
sets. John’s suggestion is the easiest way to change the field
name.<BR><BR>-Ken

calculator filter to copy one dataset to another. Change the name of the
scalar array you are displaying. when you enable the colour legen for the
new data, it will have a new name and so use a new colour lookup table.
You can now display both independently.<BR><BR>JB <BR></SPAN></FONT></DIV>

<DIV class=im>Hi all,<BR> <BR>I'm a bit of a newbie here, but I've
been having some trouble trying to figure out a way of creating multiple
color gradients and legends on the same image. In other words, I have an
object that I use a contour filter for that should have a different
gradient than another object with a different contour filter, but the
moment I change the color gradient for one, the other automatically
changes. Is there a way to create two contour filters with different
color maps and legends?<BR> <BR>Thanks,<BR>Dae Il <BR><BR>
