Plotting multiple figures in Matlab - matlab

Question

I am working with some matlab code that processes data (in a Kalman Filter) and creates a series of contour plots. It has been running on a RHEL 4 server in matlab 2006a for a few years, but my boss recently requested that all servers be updated to RHEL 6...and at least matlab 2007a. I have worked out all the depreciations between these versions, but I am still having one major problem.
The code that creates and prints different contour plots is working for whichever of the three plots is created first. It looks like this:
Unfortunately the next two plots look like this:
The three figures are plotted independently in separate functions and I use clf("reset"); before and after creating each figure. Each function works in and of itself, but when all three are plotted the second and third figures are all messed up. Has anyone else had this problem? Here is the code that creates one of the figures.
function Crd = TEC_plot(ITEC,RT,Param,Input,t,OutPath,RxExtAll,Time)
% Generate TEC plot
Function_for_Spline_Smoothing = [.05 .1 .05; .1 .4 .1; .05 .1 .05];
ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
% ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
% ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
earth('CAMERA',RT.Camera,'FIG',1);

Answer 1

Try to not use clf which will clear your whole figure but use the figure in between to open three independant figures. See it it'll work :)
Edit: That's just guessing without actually seeing your code

Answer 2

One guess might be with the code that generates your final PNG file. Your second figure appears to be incorrectly cropped when converting from JPG to PNG.
First the print command is fixed to use whatever is in figure 1. So, to ensure that you are plotting using figure 1 use the command figure(1) to specify this. Alternatively, change the print command to to read print(gcf ... to print the current figure.
Also, note you could generate the PNG file directly with print as in
print(gcf,'-dpng','-r1000',filename(...))
and skip the conversion from PS to JPG to PNG step.
The hard-coding the figure window in the print might explain why things work independently but not together if the you have multiple figure windows available. Just a guess.
