@title[#:tag "nonrenderer"]{Nonrenderers}
|
|
|
|
The following functions create @deftech{nonrenderers}, or plot elements that draw nothing in the plot.
|
|
|
|
@doc-apply[x-ticks]
|
|
@doc-apply[y-ticks]
|
|
@doc-apply[z-ticks]{
|
|
The @racket[x-ticks], @racket[y-ticks] and @racket[z-ticks] return a nonrenderer that adds custom ticks to a 2D or 3D plot.
|
|
|
|
Although @racket[ticks-add] allows placing arbitrary major and minor ticks on an axis, it does not allow them to be formatted differently from the other ticks on the same axis.
|
|
Use one of these functions to get maximum control.
|
|
|
|
@examples[#:eval plot-eval
|
|
(parameterize ([plot-x-ticks no-ticks])
|
|
(plot (list (function sin (- pi) pi)
|
|
(x-ticks (list (tick (- pi) #t "-π")
|
|
(tick (* -3/4 pi) #f "")
|
|
(tick (* -1/2 pi) #t "-π/2")
|
|
(tick (* -1/4 pi) #f "")
|
|
(tick 0 #t "0")
|
|
(tick (* 1/4 pi) #f "")
|
|
(tick (* 1/2 pi) #t "π/2")
|
|
(tick (* 3/4 pi) #f "")
|
|
(tick pi #t "π")))
|
|
(axes))))]
|
|
When considering using one of these functions, remember that minor tick labels are never drawn,
|
|
and that including a @racket[z-ticks] nonrenderer will not add extra contour lines to contour plots.
|
|
}
|
|
|
|
@doc-apply[invisible-rect]{
|
|
Returns a nonrenderer that simply takes up space in the plot. Use this to cause the plot area to include a minimal rectangle.
|
|
@examples[#:eval plot-eval
|
|
(plot (list (function sin (- pi) pi)
|
|
(invisible-rect #f #f -2 2)))]
|
|
}
|
|
|
|
@doc-apply[invisible-rect3d]{
|
|
Returns a nonrenderer that simply takes up space in the plot. Use this to cause the plot area to include a minimal rectangle.
|
|
See @racket[invisible-rect] for a 2D example.
