[Matplotlib-users] Line2D visible in axes

[Mads I. <mad...@gm...>]

Hi,

I have an 'axes' and some Line2D instance 'line' which is part of the 
axes artists.

Suppose the plot has been zoomed so only a small window of the original 
axes is visible. Is there a fast/convenient method that can be used to 
test if a Line2D object is visible at the current zoom level.

Of course you can test with

data = line.get_xydata()
(x_0, x_1) = axes.get_xlim()
(y_0, y_1) = axes.get_ylim()

invisible_x = (data[:,0].max() < x_0) or (data[:,0].min() > x_1)
invisible_y = (data[:,1].max() < y_0) or (data[:,1].min() > y_1)

but there might be something more convenient method/approach for this.

Best regards,

Mads
