First you have to decide which points you want to have marked differently.
If I understand you correctly, you want all data with a line, and every some
number (for ex. 4) of data points with a different mark - then use:
plot 'file' u 1:2 with lines, 'file' every 4 u 1:2 with points (or dots or
whatever)
Hope it helps.
