I am working on a D3 bar chart as per the mock-up below:
How do I make the bars to have random colors?
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
d3 has 4 built in color palettes.
link for the built in color palettes.
This tutorial is good on using specific colors for specific element.
tutorial by Jerome Cukier.
And the official
site for d3 colors.
Fiddle - Note: In the fiddle I've passed the colors by adding colors in the data.
It can even be done by passing the colors from a different variables.
Hope this helps.
