Hola Alejandro, sure, I think this can do the job: write a function to calc your X values: def x(data): X=[] c=1 for i in data: if i>0: X.append(c) c+=1 return X then your data without zeros in a pythonic way: >>> my_y_data=[i for i in data if i>0] with data=[1,3,6,1,2,0,0,0,0,1,4,7,9,4,2,4,6,0,0,0,0,0,0,0,0,0,0,0,0,1,3,5,6,7,8] then you can plot: >>> plot(x(data), my_y_data) Hope I helped !! Suerte. Hasta otra.
