Chaco 标记属性

Question

I am looking for a way to use empty circles as markers in Chaco (something like using markeredgecolor in matplotlib). Unfortunately, I haven't been able to find a list of properties that can be passed to enthought.chaco.api.Plot.plot() to do that, so does anyone know how to do that? (A pointer to a decent Chaco doc would be even nicer...) Thanks, Antony

Answer 1

plot.plot(("index", "value", "color"),
    type="cmap_scatter",
    name="my_plot",
    color_mapper=jet,
    marker = "square",
    fill_alpha = 0.5,
    marker_size = 6,
    outline_color = "black")

The above is directly from the chaco example cmap_scatter.py: Annotated Chaco Examples

Answer 2

When in doubt, always turn to the src-code:-) It looks like Plot is implemented here and the src-code is heavily commented, including examples.

Just out of curiosity (since I'm a big fan of matplotlib), why chako, does it offer something not available in matplotlib? :-)
