Readme is not clear

1-) Where does usePriceHistory come from?
2-) Is priceHistory an array or an object? What value should it contain?
Thank you

[Wilmela]

Same here.

[shawnob2123]

Agreed. Show imports and possibly a better use case

Unsure how to use priceHistory too. Very unclear in the docs.

Hey @Montchy can I pick this up?

I found some examples here: https://github.com/margelo/react-native-graph/blob/main/example/src/data/GraphData.ts

function weightedRandom(mean: number, variance: number): number {
  var distribution = gaussian(mean, variance)
  // Take a random sample using inverse transform sampling method.
  return distribution.ppf(Math.random())
}

export function generateRandomGraphData(length: number): GraphPoint[] {
  return Array<number>(length)
    .fill(0)
    .map((_, index) => ({
      date: new Date(
        new Date(2000, 0, 1).getTime() + 1000 * 60 * 60 * 24 * index
      ),
      value: weightedRandom(10, Math.pow(index + 1, 2)),
    }))
}

export function generateSinusGraphData(length: number): GraphPoint[] {
  return Array<number>(length)
    .fill(0)
    .map((_, index) => ({
      date: new Date(index),
      value: Math.sin(index),
    }))
}

The README example was updated in PR #136. It now shows where the graph data comes from and the expected GraphPoint[] shape, so the documentation questions here are addressed.
