You’re passing in specific rgb values, so matplotlib can’t construct a
colormap, because it doesn’t know how it relates to your original data.
Instead of mapping the values to RGB colors, let
scatterhandle that for
you.
Instead of:
# Mapping the values to RGBA colorsdata = plt.cm.jet(data[x_data, y_data])pts = plt.scatter(x_data, y_data, marker='s', color=data)
Do:
pts = plt.scatter(x_data, y_data, marker='s', c=data[x_data, y_data])
(Just pass in to
cwhat you were originally passing into
plt.cm.jet.)
Then you’ll be able to construct a colormap normally. The specific error is
telling you that the colors have been manually set, rather than set through
set_array(which handles mapping an array of data values to RGB).
