Set of visualisations primitives for building visualisations.

Installation

Usage

import * as React from "react";
import { DataFrame } from "@operational/frame";
import { Axis, Bars, Chart, useScaleBand, useScaleLinear } from "@operational/visualizations";

const frame = new DataFrame(/* ... */);

interface BarChartProps<Name extends string> {
  width: number;
  height: number;
  margin: number | [number, number] | [number, number, number, number];
  data: BarsProps["data"];
  categorical: Name;
  metric: Name;
}

/**
 * Example of how you can compose more complex charts out of 'atoms'
 */
const BarChart = <Name extends string>({ width, height, margin, data, categorical, metric }: BarChartProps<Name>) => {
  const categoricalScale = useScaleBand({ frame: data, column: categorical, range: [height, 0] });
  const metricScale = useScaleLinear({ frame: data, column: metric, range: [0, width] });

  return (
    <Chart width={width} height={height} margin={margin} style={{ background: "#fff" }}>
      <Bars
        direction={"horizontal"}
        data={data}
        categorical={categorical}
        metric={metric}
        categoricalScale={categoricalScale}
        metricScale={metricScale}
        style={{ fill: "#1f78b4" }}
      />
      <Axis scale={categoricalScale} position="left" />
      <Axis scale={metricScale} position="bottom" />
    </Chart>
  );
};

const App = () => (
    <BarChart metric="sales" categorical="Customer.City" width={300} height={300} margin={[20, 60]} data={frame} />
