[Gnuplot-info] ploting lines/points

[Zhenhai D. <du...@cs...>]

Hi,

I want to plot all the data in a "line", however, I also want to 
put some "point marks" (such as rectangle, asterisk etc) for some
of the points. Can anyone help me on this?

Basically, I have a large set of data, if I use linespoints for ploting, I 
cannot differeniate the linespoints for different data set (because there 
are so many points). On the other hand, if I use the every command, some 
data value will be ignored.

Many thanks,

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.

Sorry for very late reply and maybe somebody might have answered.
But, I wanted the samething and I made a patch for it.

You can do what you want by
plot "data_file" w l, "" every 50 w p
but it takes more typing.
