GNUPLOT v/s. ORIGIN plotting (Smoothing using B-Spline)
$begingroup$
This is pretty common question on smoothing of data in Gnuplot. My question, however, relates to smoothing of current vs. voltage data (acquired by applying triangular wave potential) in Origin vs. Gnuplot. Data is given below:

When I plot this data in Origin, I use Connect--->B-Spline, I get a smooth curve. When I use Gnuplot, I plot the data using the command
begin{equation}
mathtt{
plot,, [-2.2:-1.9], , 'CV.dat' ,,u,, 1:2 ,,smooth , csplines}
end{equation}
I do not get the desired result. As a matter of fact, 50% of the data do not show. Is it possible in Gnuplot to carry out what I intend to do?
