How to use it:

1. Install and import the jsGantt.

# NPM
$ npm i jsgantt-improved
import {JSGantt} from 'jsgantt-improved';

2. Or directly load the required JS/CSS files in the document.

<!-- OR -->
<link rel="stylesheet" href="dist/jsgantt.css" />
<script src="dist/jsgantt.js"></script>

3. Create an empty container to hold the Gantt Chart.

<div style="position:relative" class="gantt" id="example"></div>

4. Create a new instance of the Gantt Chart.

  • pDiv: Selector of the chart container,
  • pFormat: “hour”, “day”, “week”, “month”, or “quarter”
// JSGantt.GanttChart(pDiv, pFormat);
const myChart = new JSGantt.GanttChart(document.getElementById('GanttChartDIV'), 'day');

5. Load task data from JS objects, JS strings, JSON, or XML.

// object
myChart.AddTaskItemObject({
  pID: 1,
  pName: "Name 1",
  pStart: "2023-02-25",
  pEnd: "2023-03-17",
  pPlanStart: "2023-04-01",
  pPlanEnd: "2023-04-15 12:00",
  pClass: "",
  pPlanClass: ""
  pLink: "",
  pMile: 0,
  pRes: "Brian", // resource name
  pComp: 0,
  pGroup: 0, // 0 = normal task, 1 = standard group task, 2 = combined group task
  pParent: 0, // parent ID
  pOpen: 1, // 1 = open, 0 = closed
  pDepend: "", // comma separated list of ids this task is dependent on
  pCaption: "",
  pCost: 1000,
  pNotes: "Some Notes text",
  pBarText: "ex. bar text",
  category: "My Category",
  sector: "Finance"
});
// JSON
JSGantt.parseJSON('./data.json', myChart);
// XML
JSGantt.parseXML("./data.xml", myChart);

4. Draw the chart on the page.

myChart.Draw();

5. Remove a task item by ID.

myChart.RemoveTaskItem(5);

6. Clear all tasks.

myChart.ClearTasks()

7. Set options.

g.setOptions({
  vCaptionType: 'Complete',  // Set to Show Caption : None,Caption,Resource,Duration,Complete,     
  vQuarterColWidth: 36,
  vDateTaskDisplayFormat: 'day dd month yyyy', // Shown in tooltip box
  vDayMajorDateDisplayFormat: 'mon yyyy - Week ww',// Set format to display dates in the "Major" header of the "Day" view
  vWeekMinorDateDisplayFormat: 'dd mon', // Set format to display dates in the "Minor" header of the "Week" view
  vLang: lang,
  vAdditionalHeaders: { // Add data columns to your table
    category: {
      title: 'Category'
    },
    sector: {
      title: 'Sector'
    }
  },
  vShowTaskInfoLink: 1, // Show link in tool tip (0/1)
  vShowEndWeekDate: 0,  // Show/Hide the date for the last day of the week in header for daily view (1/0)
  vUseSingleCell: 10000, // Set the threshold at which we will only use one cell per table row (0 disables).  Helps with rendering performance for large charts.
  vFormatArr: ['Day', 'Week', 'Month', 'Quarter'], // Even with setUseSingleCell using Hour format on such a large chart can cause issues in some browsers
  vScrollTo: new Date(),
  // EVENTS
  // OnChangee
  vEventsChange: {
    taskname: console.log,
    res: console.log,
  },
  // EventsClickCell
  vEvents: {
    taskname: console.log,
    res: console.log,
    dur: console.log,
    comp: console.log,
    start: console.log,
    end: console.log,
    planstart: console.log,
    planend: console.log,
    cost: console.log,
    additional_category: console.log, // for additional fields
    beforeDraw: ()=>console.log('before draw listener'),
    afterDraw: ()=>console.log('before after listener')
  },
  vEventClickRow: console.log,
  vEventClickCollapse: console.log
