scatter chart after panning after zoom to a limit, the lines are missing

Hi, 
I am working with achart engine 1.1.0. And uses scatter chart with some 
customization. But when panning after zoom to a limit, the lines are missing. 
We using Samsung galaxy s4 and s3. We havent put the patch mentioned here. And 
need to confirm whether this patch already present in the latest version ?

What steps will reproduce the problem?
1. Zoom to some limit say 6
2. Pan the chart towards right
3.

What is the expected output? What do you see instead?
Lines are missing

Please provide a source code snippet that we can use to replicate the
issue.

What version of the product binary library are you using?
1.1.0

Please provide any additional information below.
