Interpolating graph in gnuplot

Im trying to plot a graph in gnu plot using this command

    plot 'temp.txt' using 1:3 title 'humidity' with lines smooth csplines,

   'temp.txt' using 1:2 title'temprature' with lines smooth splines

but the curves are not smooth enough as you can see in the image enter image description here

I want the curves to be more smooth by interpolating the existing data.

"smooth kdensity" will get you smoother curves, but it won't be from interpolation. The curves will not go exactly through any of the points.

Your data sampling is probably higher than your csplines sampling. Try set samples 1000 before the plot command.
