glgui plot - part-cw/lambdanative GitHub Wiki
(glgui-plot g x y w h xval yval color lines? . axis)
glgui-plot adds an XY plot (or multiple XY plots) to the screen.
Note: When x or y values change, the entire texture is recreated. This is computationally expensive! Hence if only a single value (or a small list of values) are added frequently, consider using (glgui-trace g x y w h trace color . lim) instead!
Parameter | Description |
---|---|
g | The Graphical User Interface (GUI) this widget belongs to |
x | Lower left corner along the x-axis in pixels |
y | Lower left corner along the y-axis in pixels |
w | Width of the widget in pixels |
h | Height of the widget in pixels |
xval | List (or list of lists) of x-values to be plotted |
yval | List (or list of lists) of y-values to be plotted |
color | Dot color (or list of colors) |
lines | Connect dots with lines, as boolean (or list of booleans) |
axis | Optional: Axis limits '(xmin xmax ymin ymax) |
Example
Example 1: Draw a mixed plot, combining both a Green lineplot, with a Red scatterplot superimposed. Axis are limited to x: -10 to 10 and y: -10 to 10.
(let* ((w (glgui-width-get))
(h (glgui-height-get))
(dim (min (/ w 2) (/ h 2)))
(x (list 0 1 2 3 4 5 5 6 7 8))
(y (list 9 8 7 5 4 3 0 2 3 1))
)
(glgui-plot gui 300 300 300 300 (list x y) (list y x) (list Green Red)
(list #t #f) (list -10 10 -10 10))
)
Attributes
Besides the parameters set in the above procedure, the widget has the following attributes that can be set using glgui-widget-set! and retrieved using glgui-widget-get:
Attribute | Default Value | Description |
---|---|---|
axiscolor | (color-fade White 0.25) | Color of x and y axis, drawn if axis are set |
