2. The vibrograph chart display

Swipe right to display the “Vibrograf” chart, historically used by watchmakers 
where each dot represents a tick or a tock over time and formed of two lines.

If the watch tends to run faster, the slopes are positive.
If the watch tends to run slower, the slopes are negative.
If the watch is perfectly accurate, the chart displays flat lines.

In case the watch has no beat error, the two lines are superimposed. If the beat 
error is greater than 0.0ms, the lines are spaced. The bigger the beat error, the 
larger the space between the lines.
