In gantt chart, I would like to pass the JSON data from model to JQChartwith Y-axis as titles and X-axis as time differences and using JQuery i wanted to set the series values. Is that possible to do it? If so, could you please provide me an example?

Hi,

You can prepare your data to be in format:
Code:
[ ['Phase 1', new Date(2010, 0, 1), new Date(2010, 0, 30)],
  ['Phase 2', new Date(2010, 0, 1), new Date(2010, 0, 10)], ... ]


http://www.jqchart.com/jquery/chart/GanttCharts/GanttChart

and pass the data to chart like in this example:

Thanks for your reply. But how will you map the xvalues, FromValues, ToValues in the series in JQuery? I saw the examples are in aspx, razor. But in JQuery Is that possible?

Basically how the Gantt chart is drawn in JQUERY?

Also the Series.Gantt() in the razor syntax is showing error. The Gantt() is not available.

You can try using the following code to convert your data:
Code:
var ganttModel = [
            { task: "Task 1", from: new Date(2012, 1, 1), to: new Date(2012, 1, 2) },
            { task: "Task 2", from: new Date(2012, 1, 4), to: new Date(2012, 1, 6) },
            { task: "Task 3", from: new Date(2012, 1, 10), to: new Date(2012, 1, 20) }
        ];

        function convertModelToGanttData(model) {
            var ganttData = [];

            for (var i = 0; i < model.length; i++) {
                var item = model[i];

                ganttData.push([item.task, item.from, item.to]);
            }

            return ganttData;
        }

        $('#jqChart').jqChart({
            series: [
                {
                    type: 'gantt',
                    data: convertModelToGanttData(ganttModel)
                }
            ]
        });


You need to download the latest version (3.7.5.0) of jqChart, so you can use Gantt chart.

Hi,

Can we pass this data from Model?

var ganttModel = [
{ task: "Task 1", from: new Date(2012, 1, 1), to: new Date(2012, 1, 2) },
{ task: "Task 2", from: new Date(2012, 1, 4), to: new Date(2012, 1, 6) },
{ task: "Task 3", from: new Date(2012, 1, 10), to: new Date(2012, 1, 20) }
];


Thanks,
Venkatesh

Sure, just call convertModelToGanttData function, which converts the model to gantt data:

Code:
function convertModelToGanttData(model) {
            var ganttData = [];

            for (var i = 0; i < model.length; i++) {
                var item = model[i];

                ganttData.push([item.task, item.from, item.to]);
            }

            return ganttData;
        }
....


{
    type: 'gantt',
    data: convertModelToGanttData(ganttModel)
}
