[FLASH-USERS] Variable output format

[Sylvia Plöckinger]

Hi Trae,

	for very simple line plots I usually use the loaddata routine in IDL, 
which is located in the tools/fidlr3.0 directory

In case you use IDL, the syntax would be something like:

t = loaddata(<filename>, 'temp')

or if you want to have x and y coordinates:

t = loaddata(<filename>, 'temp', xcoords = x, ycoords = y)
 
t is an array with the values for the variable temp (or any other), x and y give the coordinate informations and:

plot, x, t[*,4]      

should do a simple line plot. 

Greets, 

Sylvia

I opened the hdf5 file and see the variables I need but I am confused by their shape.  The ion variables, as well as velocity and temperature have a shape of (5,1,8,8).  Does anyone know what these dimensions correspond to and/or how to map the variables to position?
