Plots are not visible in Screen, ScrollView and Carousel

After a chat with @tshirtman, He found out the problem is with stencilbuffer and by changing line 139 of __init__.py of graph module to:

self._fbo = Fbo(size=self.size, with_stencilbuffer=False)

It will be visible in my example, but then there will be many problems with new features of graph (SmoothLinePlot).

Exploring kivy codes for hours and found this, commenting it lets graph to be shown:

<ScreenManager>:
    canvas.before:
        StencilPush
        Rectangle:
            pos: self.pos
            size: self.size
        StencilUse
    canvas.after:
        StencilUnUse
        Rectangle:
            pos: self.pos
            size: self.size
        StencilPop

Same problem with Carousel which is an StencilView.

The same problem occurs when putting a graph in a ScrollView.

From above: "line 139 of init.py of graph module to:..."
It was line 146 for me. Worked like a charm.

Hi, I tried to run this program, plot is not visible??
Am I missing something? there is no problem in importing graphs.

Plz help soon!

Changing with_stencilbuffer=True to with_stencilbuffer=False in the garden.graph init.py module saved my life! I wish I'd have found this page 2 hours ago though!
Thanks @tshirtman & @mostafar!

P.s. @snarfums: It was line 153 for me, go figure!

Just wanted to add that this is still an ongoing issue. Setting stencilbuffer to False fixed it for me. Thanks!

after changing 'with_stencilbuffer=False' , my plot going out of preview(snapshot attached) and if I dont change plot is not shown. am in deadlock :( . am working on real-time graph simulation..

This is also required to made it working on iOS

Had to search for ages for this, thanks!

I stumbled into the same problem as @gnarendra89, as you can see from the image:

The above graph has a logarithmic y-axis and a linear x-axis, while the bottom graph has both x and y-axis in linear scale.
What I find interesting is that for a linear scale axis the plots are drawn correctly, as can be seen in the bottom graph.

I think this shift in graph drawing might be related to this #45.

Does anyone know what might be causing the problem?

Edit: This after applying the fix proposed by @mostafar

This is the same as kivy/kivy#1578

This has been fixed in Kivy master (v1.10.1.dev0, git-1114ebf, 20171229)
