MatLab: Plotting in GUI uicontrol

[Philosophaie]

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?

It looks like you're missing the line that actually draws the plot on the axes. Try adding this line after your loop:

plot(x,y);

This should draw the plot on the axes you have specified.

It appears that you are attempting to plot multiple lines in a for loop within a GUI. In order for the plot to appear on the axes, you will need to use the "plot" command within the axes command that you have already set up. Additionally, you will need to specify the x and y coordinates for each line within the plot command. You may also need to adjust the axes limits and labels in order to properly display your data. It may also be helpful to use the "hold on" command before the for loop to ensure that all of the lines are plotted on the same axes. I would suggest looking into the documentation for the "plot" and "axes" commands in order to fully understand how they work within a GUI.
