Plotting support. Initializes the IUP MglPlot library when loaded.
Creates a plotting canvas.
(call-with-mglplot [handle ihandle?] [proc (-> ihandle? any)] #:dimension [dimension integer? 2]) → any
Calls the given procedure with the given plotting canvas handle and ensures that the canvas is ready to receive data of the given dimension. Returns whatever the given procedure returns.
(mglplot-add! [handle ihandle?] [x (or/c string? real?)] [y real?] [z (or/c real? #f) #f] [sample-index (or/c integer? #f) #f] [index (or/c integer? #f) #f]) → void?
Adds a sample to the given plotting canvas. Whether
must be a string or a real number depends on the setting of the
dimension argument to the
call-with-mglplot invocation that
created the dataset: One-dimensional data sets can be labeled with
strings while two- and three-dimensional data sets consist of numeric
#f, the sample is appended to the
dataset and the call to
mglplot-add! must be within the dynamic
context of a call to
sample-index is a number, the sample is inserted into the
dataset before the given sample index. The call to
does not have to be within the dynamic context of a call to
call-with-mglplot in this case.
The dataset to which the new sample should be added may be specified explicitly
by its index through the
index argument. If the
argument is false, the current dataset of the plotting canvas is used.
(mglplot-x/y/z->pixel-x/y [handle ihandle?] [x real?] [y real?] [z real? 0.0]) → (values integer? integer?)
Transforms plot coordinates into pixel coordinates.
(mglplot-paint-to [handle ihandle?] [format string?] [file string?] [width integer? 0] [height integer? 0] [dpi real? 0.0]) → void?
Paints the plot's contents into an image file. The format should be
"SVG". If the width, height
and resolution are not specified, the same values as for the on-screen
representation of the plot are used.
