From the json user gives the color to the individual bars such as
[
{ "Sales": 2,"Month":"Jan","color":"#000000"},
{ "Sales": 2,"Month":"Feb" ,"color":"#0afbaf"},
{ "Sales": 5, "Month": "Mar" ,"color":"#c0f0f0"},
{ "Sales": 1, "Month": "Apr" ,"color":"#d0f0d0"},
{ "Sales": 8, "Month": "May" ,"color":"#aaaaaa"},
{ "Sales": 5, "Month": "Jun" ,"color":"#110101"},
]
by using the setcolor() method i can able to change the default color to user specified color. But in the legends i am getting the default color and single value only displayed init.
