I have yaxis from 0 to 100. I want a grid line after every 10 units. How can I do that? That is, how can I draw grid lines after each 10 units?
The ytics
variable controls how often or sparse the y
scale values will be printed and thus the grid lines will be drawn.
set ytics 10 # y scale marks and values will be at every 10th unit
set grid # grid turned on at each scale values
replot # replot your graph
The mytics
controls the minor marks on the y
scale. The set grid mytics
makes the y
scale minor grid lines visible.
Have a look at "help grid", you probably want to do something like
set yrange [0:100]
set xrange [0:10]
set grid ytics mytics # draw lines for each ytics and mytics
set mytics 2 # set the spacing for the mytics
set grid # enable the grid
plot sin(x)*100
