Hi!
I am rather new to sage too! I have tried your examples. I've used
polar_plot() instead of arc() for figure 1 (there is disk() aswell):
myArc = polar_plot(4, (0, 3*pi/2), ymin=-4, color='red', fill=True,
fillcolor= 'green', fillalpha=0.2, axes_labels=['X', 'Y'],
fontsize=15)
radiusLine = line2d([ (0,0), (2*sqrt(2), 2*sqrt(2)) ], color='black',
thickness=2)
mytext = text("R",(1.6, 2), fontsize = 20, color='black')
figure1 = myArc + radiusLine + mytext
And for figure 2, I used polygon():
figure2 = polygon([(0,0), (2,1), (0,3)], alpha=0.5)
Show up, figure 1:
figure1.show()
You can always save the figures in svg format for further editing with
a WYSIWYG svg editor. I use inkscape.
figure1.save('/home/username/Desktop/figure1.svg')
You can read the doc about any function right in the notebook. For
example, just type:
polygon?
Cheers! Pablo
