Hi all!
Recently I discovered the 4.1 version of gnuplot and the image
plotting facilities. Without knowing, I was waiting for this. A big
thank you guys!
My question: If I plot an image now I get the pixel numbers along the
X and Y axis. Is it possible to supply values for the X and Y axis
(thus besides the image). Or is it possible the give an expression
for the X and Y axis. Instead pixel numbers I want to give
micrometers as the images are microscopic of nature. Can be done by
another datafile with X and Y values, or by an expression, let say
X*(MicroMeterPerPixelValue) for the X axis.
Your ideas are appreciated!
P.S. There is no such thing as a mubar functionality in gnuplot, is
there? I mean a little line onto the image indicating a specified
amount of distance. Of course I can program this directly into the
image by making a line of pixels black (or white), but if there is
some gnuplot functionality for that I sure like to use it.
Thanks, Mark
