How Do I...

import colight.plot as Plot

my_data = [[1, 1], [2, 1.5], [3, 1.25], [4, 2]]

(my_plot := Plot.line(my_data, r=10))

Show a grid

my_plot + Plot.grid()

Label axes

Add an options object to your plot, putting a "label" in the options for the "x" or "y" axis:

my_plot + {"x": {"label": "My x axis"}, "y": {"label": False}}

Hide axes

Pass False for an axis label (see above), or use Plot.hideAxis:

my_plot + Plot.hideAxis() & my_plot + Plot.hideAxis(y=True)

Assign colors to particular marks

  • In a mark use Plot.constantly(<label>) for a color value like fill or stroke. The <label>, a string, is how you will refer to this color and it will show up in the legend.
  • Then use Plot.colorMap({<label>: <color>}) to specify a color for that label.
  • Include Plot.colorLegend() to show the legend. See the color page for more details.
(
    Plot.line(my_data, stroke=Plot.constantly("Progress"))
    + Plot.colorMap({"Progress": "orange"})
    + Plot.colorLegend()
)
