Markers

The functionality is available in PRO Edition only

PRO

Markers allow highlighting certain dates in Gantt, which makes the chart more informative.

Adding a marker

To add markers, add the markers objects to the markers array:

import { getData } from "./data";
import { Gantt } from "@svar/react-gantt";

const data = getData();
const markers = [
   {
     start: new Date(2020, 2, 4),
     text: "Start Project",
   },
];

export default function App() {
  return (
    <Gantt
      markers={markers}
      tasks={data.tasks} />
  );
}

Customizing the markers style

To change the default style, redefine global css variables for markers.

Default values:

    --wx-gantt-marker-font: 500 12px Roboto;
    --wx-gantt-marker-font-color: #fff;
    --wx-gantt-marker-color: rgba(6, 189, 248, 0.77);

Example:

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

const data = getData();
const markers = [
   {
     start: new Date(2020, 2, 8),
     text: "Today",
   },
 ];

export default function App() {
  return (
    <Gantt
      markers={markers}
      tasks={data.tasks} />
  );
}

/* App.css */
.wx-willow-theme {
  --wx-gantt-marker-font-color: yellow;
}

You can also apply the css parameter to customize the style for a specific marker:

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

const data = getData();

const markers = [
  {
    start: new Date(2020, 2, 4),
    text: "Start Project",
    css: "myMiddleClass",
  },
  //other markers
];

export default function App() {
  return (
    <Gantt
      markers={markers}
      tasks={data.tasks} />
  );
}

/* App.css */
.wx-willow-theme .myMiddleClass {
    background-color: rgba(255, 84, 84, 0.77);
}
