Zooming

Enabling default zoom settings

To enable default zooming, set the zoom property to true.

Example:

import { getData } from "./common/data";
import { Gantt } from "wx-react-gantt";

const App = () => {
  const data = getData();

  return <Gantt zoom={true} tasks={data.tasks} />;
};

export default App;

Configuring zoom settings

To configure zoom settings, change the required parameters of the zoom property.

Example:

import { getData } from "./common/data";
import { Gantt } from "wx-react-gantt";

const data = getData();

const zoomConfig = {
  maxCellWidth: 400,
  level: 3,
  levels: [
    {
      minCellWidth: 200,
      scales: [{ unit: "year", step: 1, format: "yyyy" }],
    },
    {
      minCellWidth: 150,
      scales: [
        { unit: "year", step: 1, format: "yyyy" },
        { unit: "quarter", step: 1, format: "QQQQ" },
      ],
    },
    {
      minCellWidth: 250,
      scales: [
        { unit: "quarter", step: 1, format: "QQQQ" },
        { unit: "month", step: 1, format: "MMMM yyy" },
      ],
    },
    {
      minCellWidth: 100,
      scales: [
        { unit: "month", step: 1, format: "MMMM yyy" },
        { unit: "week", step: 1, format: "'week' w" },
      ],
    },
    {
      maxCellWidth: 200,
      scales: [
        { unit: "month", step: 1, format: "MMMM yyy" },
        { unit: "day", step: 1, format: "d", css: dayStyle },
      ],
    },
    {
      minCellWidth: 25,
      scales: [
        { unit: "day", step: 1, format: "MMM d", css: dayStyle },
        { unit: "hour", step: 6, format: hoursTemplate },
      ],
    },
    {
      scales: [
        { unit: "day", step: 1, format: "MMM d", css: dayStyle },
        { unit: "hour", step: 1, format: "HH:mm" },
      ],
    },
  ],
};

function App() {
  return (
    <Gantt zoom={zoomConfig} tasks={data.tasks} />
  );
}

export default App;
