I have one of NVD3.js's line plus bar charts configured as below. Of course, each series of data has its own color for the bar/line display on the chart. I'm curious if there's a built-in way to set the Y-axis associated with a particular series to the same color as that series. In my example below, that would mean that:
a) the left axis and the bar chart would be "steelblue"
b) the right axis and the line chart would be "skyblue"
I stepped through the NVD3 and D3 code a little bit looking at the axis objects, but I didn't find anything that seemed like it would set this sort of an option.
Thanks in advance for any insight into this feature, present or otherwise!
