For example, I can do: data=RandomReal[1,100]; to generated a list of 100 data points and then do: ListPlot[data[[;;;;10]]] To plot every 10th point in the list. Another approach would be to so something like ListPlot[Mean/@Partition[data,10]] But, as to whether doing something like this will actually solve your issue is impossible for me to determine. I or others could give a better answer if you provided more details of what it is you are trying to do such as the format of the files.
