Three signals on the same graph causes jitter

What steps will reproduce the problem?
1. Use a single datasets
2. Add three or more series to the dataset
3. Try to display and update the series, all in a loop.

What is the expected output? What do you see instead?

A lot of jitter and skipped frames.

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

Attached.

What version of the product binary library are you using?

v1.0.0

Please provide any additional information below.

The attached code generates the co-ordinate data once and then the only the 
co-ordinates are changed(instead of being calculated each time) each frame to 
achieve a smooth animation of a wave. This is done to reduce computational 
costs. Tested on a quad-core Asus TF201, this code displays a jittery wave. 
This might be due to faulty coding methods itself, or due to the limitations of 
the device/library. Please suggest an workaround or an alternative 
implementation for six signals with 400 samples each, updating at 24fps.
