22 Combining Plot Areas and Observations🔗ℹ

Layer a filled function area, its graph, and observation markers in one plot.

API reference: Point Markers, Scatter Plots, and Filled Areas, Visuals.

The following example places a filled function area behind its graph and adds ordered observations as diamond markers:

(define area

(function-area coordinate-axes

function

#:id 'area

#:interpolation 'smooth))

(define graph

(function-graph coordinate-axes

function

#:id 'graph

#:interpolation 'smooth))

(define observations

(scatter-plot coordinate-axes

(list (vec2 -2 1)

(vec2 0 0)

(vec2 2 1))

#:id 'observations

#:shape 'diamond))
