My app is to display data lists with different length including range (50 - 10000) elements displayed on X-Axis,
for small lists I chose 5 max visible on X-Axis, 50 for long ones.
The error occurs while transitioning from small to large data set, that requires X-Axis to be animated to match the visible points.
