how to make hollow square marks with matplotlib in python
Setting markerfacecolor='white'
does not actually make them hollow, it makes them white. In order to make them hollow, you need to set markerfacecolor='none'
.
Additionally, you need to set markeredgecolor
to the color you want.
So:
pylab.semilogy(xaxis, pq_averages, 'ks-',color='black',
label='DCTCP-PQ47.5', markerfacecolor='none', markeredgecolor='black')
Will do the job for you.
Try adding markerfacecolor
like so:
pylab.semilogy(xaxis, pq_averages, 'ks-', markerfacecolor='none', label='DCTCP-PQ47.5')
