Gnuplot minimum and maximum boundaries for autoscaling
autoscaling, gnuplot, plot, scaling
Solution
Since version 4.6 gnuplot offers a new syntax to specify upper and lower limits for the autoscaling. For your case you could use
set xrange [0:100 < * < 1000]
Quoting from the documentation:
The range in which autoscaling is being performed may be limited by a lower bound `<lb>` or an upper bound `<ub>` or both. The syntax is
{ <lb> < } * { < <ub> }
For example
0 < * < 200
sets `<lb> = 0` and `<ub> = 200`.
That syntax can be applied to both the minimum or maximum value of `set *range`.
To autoscale `xmin` but keeping it positive, use
set xrange [0<*:]
To autoscale `x` but keep minimum range of 10 to 50:
set xrange [*<10:50<*]
See the documentation about `set xrange` for more information.
Problem
How can I limit the autoscaling of gnuplot, so that, as example for the y-max, it is at least a certain value and it would autoscale up to fixed "limit"? From looking at the documentation, I only see how to fix min-, or max- end of the axis, while the other is being scaled automatically. About autoscaling on PDF page 93
