Hey Mike, sorry for posting on wrong thread. But my issue is related to d3.scaleLinear/d3.scaleTime. We are using D3 V4. Need to display date on x-axis and number on Y-axis. When set x-axis values to domain and specify ticks(5), I am facing 2 issues mentioned below.
Could you please us a direction to overcome this issue? Our organization just started using D3 so we have less help from our IT teams.
