Hello,

I have a data file of two columns(time and value). I imported data file by using 'signal builer'. And I can plot the data simply by connecting 'scope'.

But I want to adjust the number of data point in plot. For example, I would like to plot 5 data points only when whole data points are 10.

Any ideas please? I am very newbee for Matlab and Simulink...

Thanks in advance!

Hi Hyungtae,

Probably you would like to apply decimation when plotting the data? If so, open the Scope, then right-click on it and select Configuration Properties, then go to the tab Logging and you will see a checkbox named 'Decimation' where you can define the amount of points to reduce when plotting the data. See figure below.
