Syntax:
set clip <clip-type>
set noclip <clip-type>
show clip
Three clip types are supported by GNUPLOT: points, one, and two. One, two, or all three clip types may be active for a single plot.
The points clip type forces GNUPLOT to clip (actually, not plot at all) data points that fall within but too close to the boundaries (this is so the large symbols used for points will not extend outside the boundary lines). Without clipping points near the boundaries may look bad; try adjusting the x and y ranges.
Setting the one clip type causes GNUPLOT to plot the line segments which have only one of the two endpoints within the plotting region. Only the in-range portion of the line is drawn. The alternative is to not draw any portion of the line segment.
Some lines may have both endpoints out of range, but pass through the plotting area. Setting the two clip-type allows the visible portion of these lines to be drawn.
In no case is a line drawn outside the plotting area.
The defaults are noclip points, clip one, and noclip two.
To check the state of all forms of clipping, use
show clip
For backward compatibility with older versions, the following forms are also permitted.
set clip
set noclip
set clip is synonymous with set clip points. set noclip turns
off all three types of clipping.
