Smoothening of a curve

I have got a csv file with 1million data points which i have plotted in matlab and i am satisfied with the results. I want to smooth the plot that i have generated. Any help would be appreciated.

smoothdata would be a start.

[Mathieu NOE]

you probably don't need more than 1000 data point for a good enough display

so you can reduce your data processing burden by already decimating it (with decimate)

as decimate will also apply first a low pass filter , you can get both benefits in one line.

You can use the Smooth Data task in a live script to interactively adjust your smoothing settings to arrive at an acceptable result.
