Change plot scale y axis

Hello,

I have 2 vectors i want to plot but i want to change the scale.

Using the code below:

u21=[224 224 224 223 218 218 217];

beta1=[0 0.19 0.26 0.38 0.76 0.83 0.9];

plot(beta1,u21,'-*');

xlabel('beta')

ylabel('U[V]')

grid on

I have obtained this:

But i want my plot to look like this, more like a straight line. The numbers on the y axis in this picture are 0:50:250 where as in my plot from above are exactly the numbers inside the vectors.

plot(beta1,u21,'-*');
xlabel('beta')
ylabel('U[V]')
ylim([0 250]) % use ylim
