I am working on a project, and I am trying to graph an ascent rate where the y axis is feet and the x axis is minutes. I want it to plot a point every minute, where it increases 2000 feet per minute until the cruising altitude. I have to use a for loop, and so far I have got it to plot the points on the y axis but not the x axis. This is also based off of a GUI, so the numbers below are able to be changed. sa= starting altitude, A1=crusing altitude, ar=ascent rate, FS=font size
sa=0;
elevation=525;
A1=30000;
minutes=135;
x=elevation:2000:A1;
for i=1:length(x)
ar(i)=sa+x(i);
end
FS=12;
%axes(handles.timevsheight);
plot(0,ar,1,ar,'-o r','linewidth',2);
xlabel('Time (Minutes)','Interpreter','latex','FontSize',FS);
ylabel('Height (Feet)','Interpreter','latex','FontSize',FS);
xlim([0 minutes+5])
ylim([0 A1+1000])
title('Time vs Height')

Based on your labels you want to plot the altitude versus time. Have you tried creating vectors with paired data? Because that is what you will need in the end: pairs of altitude and time. I don't fully understand what you're doing in your code to be able to tell you what exactly you should change to get what you need.

I need the x value to increase by one everytime instead of it being a straight line. (0,525) (1,2525)(2,4525)etc
