Can we change the format in barchart

[thiyaga05]

• The barchart needs the data, keys and indexby is to mandatory with some format in nivo. Can we change that format (for example)
  data = [
  { quarter: 1, earnings: 13000 },
  { quarter: 2, earnings: 16500 },
  { quarter: 3, earnings: 14250 },
  { quarter: 4, earnings: 19000 }
  ];
  keys={["earnings"]}
  indexBy="quarter"

can we have the data as

data= [
[
"West",
206306.20716774464
],
[
"East",
157020.43506669998
],
[
"Central",
114640.8310316801
],
[
"South",
95591.81726551056
]
]

key = {null} and indexby {null}

or in another wise like

xAxis : [
"West",
"East",
"Central",
"South"
]

yAxis :[
206306.20716774464,
157020.43506669998,
114640.8310316801,
95591.81726551056
]

therefore data=[

xAxis, yAxis
]
key : xAxis
indexby: yAxis

is there any other possibilites to use like any of those?
