#2201 — Multiplot on wxt terminal

Hi! I need a little help about gnuplot in a C source code.
I'm working on linux (Debian testing) Gnuplot 4.6

Now I have a C code that produce the polar plot of a radiation pattern of an antenna.
If I use the x11 terminal all working but if I use the wxt terminal I have problems (the picture in wxt is better than in x11).

I select the multiplot option to realize a circular grid (radii and circumferences) using the "set parameter" by mean the t parameter from 0->2pi
(x=R*cos(t),y=R*sin(t)) for arcs and to 0->1 to (x=P1x + t*(P2x-P1x),y=P1y + t*(P2y-P1y)) for radii. Than I put labels around and out the max circumference and  labels into the circumference (in this last case using rectangles over the grid and under the labels).

Then with only 1 instruction a plot 2 curves (radiation patterns) stored in 2 files and a radius to point out a main direction using the parameter notation. 

If I use the wxt terminal some times the white screen appears without graph.
Pushing the key q I can see that the grid start to appears but some times the radiation patterns do not appear. 

I observed also that if I erase the instruction "unset multiplot" the times that all the picture appear are more that the times that the run is in block.

A summary of the main instructions that I use are 
- wxt terminal
- set/unset multiplot
- set parameters
- set labels
- set object rectangle

Please, could you help me?
Thank you In Advance.

What was wrong with 'set polar' and 'set grid polar'?

My knowledge of gnuplot.
I'm not able to customize the polar grid like I want.
I sent you an example of picture realized by mean of gnuplot, drawing all the lines and putting all the labels not in automatic way.
Any suggestions well be welcome.

There really isn't much in your picture that the 'poldat.dem' example 
doesn't already do.  You may want to study that.

For my knowledge of Gnuplot I don't agree with you but thanks for your time in any case.
