[HELP] About the axes logo

[ZiguoAtGitHub]

Hi Marco,
I met two problems with the following example script.
The first is there is no axes logo shown at the bottom-left corner with vedo version 4.4 but it is shown with version 4.3.
The second is it raised "AttributeError: 'Lines' object has no attribute 'render'" when plt.render() was called in the scene which includes Line actors only.

Any responses will be appreciated!
Thank you!

[marcomusy]

you forgot + in

    self.plt=Lines(self.line_cell,c='blue',lw=2,alpha=0.8)

to

    self.plt+=Lines(self.line_cell,c='blue',lw=2,alpha=0.8)

for the axes it looks like a bug! i need to check it..
Consider using the class Axes() which can be managed like any other object.

The first problem is solved.
