I am using Cygwin and attempt to run a basic plot function in IDL but get the error (which I have seen here is fairly common):
% PLOT: Unable to connect to X Windows display: :0.0
% PLOT: Unable to open X Windows display.
Is your DISPLAY environment variable set correctly?
% Execution halted at: $MAIN$

I have read that:
setenv display <your IP address>:0.0
^
should make it work, but for me it just produced a sytax error as shown above under the "i". What could be a solution?

If it really is a syntax error then maybe you have the bash shell rather than the C-shell? In that case, I believe the equivalent command to setenv would be

export DISPLAY=<your IP address>:0.0
