Gnuplot vs matlab plot streamlines

Question

I am making a stream function plot with the following data points in gnuplot:

Streamdata.txt

My gnuplot code is working, but it plots to few streamlines compared when i plot it in matlab. See picture: (matlab plot on the left, gnuplot on the right)

Is there a way, so gnuplot can plot more streamlines? So the plot becomes more similar to the matlab plot

If we do

set cntrparam levels auto 10

and then plot we get

See help cntrparam for more details.
