# Change x axis increments

Hi,
I am trying to write the code for the plot in the attached image. This is what I have so far:
a = [0,10,20,30,50,80,130,210,340,550];
b = linspace (0, 50, 10);
figure;
plot(a, 50-b);
xlim([0 550]);
yticks([0 10 20 30 40 50]);
The graph needs to be a straight line. How can I achieve that? My second question is how do I set the x axis to look like the one in the attached image? Is there a way to "customize" it? I've tried the following:
a = [0,10,20,30,50,80,130,210,340,550];
b = linspace (0, 50, 10);
figure;
plot(a, 50-b);
xlim([0 550]);
xticks(a);
yticks([0 10 20 30 40 50]);
But that obviously hasn't worked. Is there a way to get the number to be evenly spaced? I also don't understand how I can get matlab to add two 10s to the x axis.
If anyone has any suggestion, I'd gretaly appreciate it!
Many thanks,
Dobs

See Axes Properties, specifically XScale, YScale, ZScale.
