I AM PLOTTING A DATA MATRIX X--- plot(X) DUE TO WHICH I AM GETTING THE FOLLOWING GRAPH

X= [-1.961 -1.527 -0.194 -1.475 -1.023 -0.188 -2.255 -1.482 -1.156 -0.150 -1.121 -0.772 -0.145 -1.709 ..... 21.297 15.975 3.164 20.255 12.603 3.304 28.146 21.848 16.397 3.259 20.872 12.974 3.408 28.946];

I want to change the x-axis from -5 to 400. but when i try to change it the x-axis plot from 0 to 45 is retained while the rest is left blank.

What i want is this;

If i change the axis for the plot using axis([0 400 0 30]),i am getting a compressed version;see below image

I want the graph to stretch to the limit of 400 without disturbing the graph. Please somebody help...

Can you share your code please so that it can be looked at because currently plot(X) doesn't plot the graph you showing your first figure

the x vector you mentioned actually goes through the y axis... and in the black and white graph the x axis have a rank from 1 to 400. you should define an other vector (for example xx) and re plot like this plot(xx,x) in which the xx contains length(x) values (same lengths as x) .xx=[0 1 5 10 15 20 80 100 150 200 250 .... 400];
