Exporting figures from cell quest: how?

I have used the same technique that Derek describes, of copying the plot to
the clipboard and pasting into a drawing program. I totally agree that BD
needs to add an export function to CQ, one that allows export as PICT,
TIFF, or other formats.

When the plot is pasted into another program, it is a bit-mapped image,
with several layers grouped. One consequence of bit-mapping is all text
prints poorly, like using a dot-matrix printer. For publications and
slides, I have edited those out and added my own labels to the axes.

To do that, one must first ungroup the figure (I use programs like Canvas
and ClarisDraw, but others are likely to work, as well). I was immediately
surprised to learn that the axes and labels are in one layer and the data
(dots or contours) are in several other layers, apparently corresponding to
"cuts" in the data. So, for a contour plot, there is one layer that
includes all contours, another that includes all but the inner contours,
another that includes all but the inner 2 contours, ad nauseum. One way to
speed up printing, is to send the top layer, that includes all data
(contours or dots), to the back, then delete all other layers. (As I
recall, the axes and labels are the top layer, so that must also be sent to
the back, even to be able to select the various layers of dots or contours.)

I echo Derek's recommendation of "getting the plots into as near the
finished article as possible before exporting." Because the pasted figure
is bit-mapped, any resizing will increase the size of dots or thickness of
lines. It will look ugly. When I want to group several histograms for
export, I use a single plot in CQ, that I have adjusted to the final size
that I want. Then I load the data for each sample into the same plot, to
assure that all plots will be the same size in the finished version.

Also, I would note a common error the I make is to select the plot
incorrectly when copying. If you click on the plot, not on the border
around the plot, the copy command is not active. I have been surprised at
times, when I thought I copied a plot, then pasted something altogether
different into my drawing program.

Hopefully, BD will implement a better way in a future release.
