Hi, I am not sure whether this has been reported before or maybe even got fixed already. When I make scatter plot and plot a point with marker = 'o' it appears as a circle in the plot as it should. It won't, however, appear in the legend.
Windows XP
Python(x,y) 2.6.0
matplotlib 0.99.1 (I think :-)
Example:
ax.scatter([x_assF[6]], [y_assF[6]], s=35, c='r', marker='o',
label='Ecological')
doesn't show in the legend. When I change the same line of code to
ax.scatter([x_assF[6]], [y_assF[6]], s=35, c='r', marker='8',
label='Ecological')
that is, the marker is now set to marker='8', then it will appear as a
circle in the legend. Is this a bug or am I messing something up here?
Finde complete code and data sets below:
