Mouseformat

The set mouse format command speci es a format string for sprintf() which determines how the mouse cursor [x,y] coordinates are printed to the plot window and to the clipboard. The default is "% #g".

set mouse clipboardformat and set mouse mouseformat are used for formatting the text on Button1 and Button2 actions { copying the coordinates to the clipboard and temporarily annotating the mouse position. An integer argument selects one of the format options in the table below. A string argument is used as a format for sprintf() in option 6 and should contain two oat speci ers. Example:

`set mouse mouseformat "mouse x,y = %5.2g, %10.3f"`.

Use set mouse mouseformat "" to turn this string o again.

The following formats are available:

Scrolling

X and Y axis scaling in both 2D and 3D graphs can be adjusted using the mouse wheel. <wheel-up> scrolls up (increases both YMIN and YMAX by ten percent of the Y range, and increases both Y2MIN and Y2MAX likewise), and <wheel down> scrolls down. <shift-wheel-up> scrolls left (decreases both XMIN and XMAX, and both X2MIN and X2MAX), and <shift-wheel-down> scrolls right. <control-wheel-up> zooms in toward the center of the plot, and <control-wheel-down> zooms out. <shift-control-wheel-up> zooms in along the X and X2 axes only, and <shift-control-wheel-down> zooms out along the X and X2 axes only.

X11 mouse

If multiple X11 plot windows have been opened using the set term x11 <n> terminal option, then only the current plot window supports the entire range of mouse commands and hotkeys. The other windows will, however, continue to display mouse coordinates at the lower left.

Zoom

Zooming is usually accomplished by holding down the left mouse button and dragging the mouse to delineate a zoom region. Some platforms may require using a di erent mouse button. The original plot can be restored by typing the 'u' hotkey in the plot window. The hotkeys 'p' and 'n' step back and forth through a history of zoom operations.

The option zoomcoordinates determines if the coordinates of the zoom box are drawn at the edges while zooming. This is on by default.

If the option zoomjump is on, the mouse pointer will be automatically o set a small distance after starting a zoom region with button 3. This can be useful to avoid a tiny (or even empty) zoom region. zoomjump is o by default.

Multiplot

The command set multiplot places gnuplot in the multiplot mode, in which several plots are placed on the same page, window, or screen.

Mx2tics

Minor tic marks along the x2 (top) axis are controlled by set mx2tics. Please see set mxtics (p. 129).

Mxtics

Minor tic marks along the x axis are controlled by set mxtics. They can be turned o with unset mxtics. Similar commands control minor tics along the other axes.

Syntax:

set mxtics {<freq> | default} unset mxtics

show mxtics

The same syntax applies to mytics, mztics, mx2tics, my2tics and mcbtics.

<freq> is the number of sub-intervals (NOT the number of minor tics) between major tics (the default for a linear axis is either two or ve depending on the major tics, so there are one or four minor tics between major tics). Selecting default will return the number of minor ticks to its default value.

If the axis is logarithmic, the number of sub-intervals will be set to a reasonable number by default (based upon the length of a decade). This will be overridden if <freq> is given. However the usual minor tics (2, 3, ..., 8, 9 between 1 and 10, for example) are obtained by setting <freq> to 10, even though there are but nine sub-intervals.

To set minor tics at arbitrary positions, use the ("<label>" <pos> <level>, ...) form of set fxjx2jyjy2jzgtics with <label> empty and <level> set to 1.

The set mfxjx2jyjy2jzgtics commands work only when there are uniformly spaced major tics. If all major tics were placed explicitly by set fxjx2jyjy2jzgtics, then minor tic commands are ignored. Implicit major tics and explicit minor tics can be combined using set fxjx2jyjy2jzgtics and set fxjx2jyjy2jzgtics add.

Examples:

set xtics 0, 5, 10 set xtics add (7.5) set mxtics 5

Major tics at 0,5,7.5,10, minor tics at 1,2,3,4,6,7,8,9

set logscale y

set ytics format "" set ytics 1e-6, 10, 1

set ytics add ("1" 1, ".1" 0.1, ".01" 0.01, "10^-3" 0.001, \ "10^-4" 0.0001)

set mytics 10

Major tics with special formatting, minor tics at log positions

By default, minor tics are o for linear axes and on for logarithmic axes. They inherit the settings for axisjborder and fnogmirror speci ed for the major tics. Please see set xtics (p. 160) for information about these.

My2tics

Minor tic marks along the y2 (right-hand) axis are controlled by set my2tics. Please see set mxtics (p. 129).
