Subject: [PATCH] Reduced number of ticks provided as hint to d3.ticks (#1012)

The number of the ticks suggested scales with 3 times as much
as the number of bins. This is unwanted since the number
of ticks is a hint to d3 as per (https://github.com/d3/d3-3.x-api-reference/blob/master/Quantitative-Scales.md#identity_ticks) The high number of suggesting ticks leads to a congested y-axis.
