We need the bar of series to be draggable and also its value can be changed on drag. For example, a user is given a chart like below link: http://demos.kendoui.com/dataviz/bar-charts/column.html. Below the chart, a table is given for data. Chart is loaded with false data. User is expected to plot the correct graph based on the table data given. For this, user will drag the bar in up/down direction to set it to the desired value.
