Having trouble plotting in a GUI. You have to first start with the axes command in the gui code. Then the plot. When you do the previous two actions noting comes up on the screen. The code:

axes('position',[1000,900,1000,900])
...
for k=9:1:-1
hold on;
for o=0:2*pi:.1;
x(k) = a(k) * (1 - (ecc(k) ^ 2)) / (1 + (ecc(k) * cos(paR(k) + o))) * cos(NR(k) + paR(k) + o);
y(k) = a(k) * (1 - (ecc(k) ^ 2)) / (1 + (ecc(k) * cos(paR(k) + o))) * sin(NR(k) + paR(k) + o);
plot(x(k),y(k));
end
end

All of the equations I am trying to plot are valid, data and all, it is just I am new to plotting in a GUI. There are probably some commands I am missing. Do you have any suggestions?
