The ecdf(x) always starts from the origin of the axis

Hi,

The curve of ecdf starts at f(x)=0.2, x=0.04, but MatLab doesn´t feel it is a good beginning, so the curve always starts from f(x)=0, x=0. I cannot change it, and it pissed me off because I cannot interpret the curve onset accurately. I am using ecdf because I want to plot the cumulative frequency distribution. I want to remove the part of the curve within the red rectangle.

Any workaround?

Thanks

The workaround I am using is paint. Old school.

Can you show the code you used to plot this?

[Jose Rego Terol]

the code is this function. Nothing less nothing more.

ecdf(x)

I have attached the variable x (cumulative_dist_freq)

[Jose Rego Terol]

Ok, I got the problem. The variable has many zeros. It should not have happened. Thanks anyways.

Try this

[f, x] = ecdf(fluc_freq);
mask = x > 0;
plot(x(mask), f(mask))

Amazing! Thanks!

I am glad to be of help!
