Intensity-graph/diagram

[Jochen48]

I like to visualize data out of a file in a intensity-graph. I used the Vi
and the array-funktions to read and filter the data respectivly. I extracted
three 1D-arrays X-Data, Y-Data and Z-Data, but when i build the requiered
2D-Array and feed it into the graph only three elements of X-Data are represented
in the graph, even so the pipe-Funktion shows more elements available.
What is wrong???

A good way to troubleshoot something like this is to display the data in a large 2-D
array on your front panel (instead of an intensity graph) and check the values in the
array. Make sure that the values are roughly in the numeric range and array
locations that you expect and verify that you are getting the expected number of rows
and columns of
data.

If this checks out, then you probably have a problem with your color ramp (Z scale on
the intensity chart). Make sure that the range of the ramp corresponds to the range
of the data that you are plotting.

Good luck,
