react-sparklines-ts/dist/dataProcessing/dataToPoints.js

Beautiful and expressive Sparklines component for React (continued)

import { max as arrayMax } from "./max";
import { min as arrayMin } from "./min";
export const dataToPoints = ({ data, limit, width = 1, height = 1, margin = 0, max = arrayMax(data), min = arrayMin(data), }) => {
    const len = data.length;
    if (limit && limit < len) {
        data = data.slice(len - limit);
    }
    const vfactor = (height - margin * 2) / (max - min || 2);
    const hfactor = (width - margin * 2) / ((limit || len) - (len > 1 ? 1 : 0));
    return data.map((d, i) => ({
        x: i * hfactor + margin,
        y: (max === min ? 1 : max - d) * vfactor + margin,
    }));
};
