Plugins are the most efficient way to customize or change the default behavior of a chart. They have been introduced at version 2.1.0 (global plugins only) and extended at version 2.5.0 (per chart plugins and options).. Using plugins. Plugins can be shared between chart instances: A callback that is called when a click event is registered on a label item. onHover: function: A callback that is called when a 'mousemove' event is registered on top of a label item. onLeave: function: A callback that is called when a 'mousemove' event is registered outside of a previously hovered label item. reverse: boolean: false

Zooming and Panning With dateTime Values . In a dateTime axis, zooming into certain sections will require axisX to change intervalType depending upon the zooming depth. For Example, Zooming in a default chart showing interval in months, would require axis to show interval in days. Sets which elements appear in the tooltip. See Interaction Modes for details. Can be set to 'x', 'y', or 'xy' to define which directions are used in calculating distances. Defaults to 'x' for 'index' mode and 'xy' in dataset and 'nearest' modes. Duration in milliseconds it takes to animate hover style changes. CanvasJS allows users to register different event handlers on dataSeries and dataPoints, legend and Chart. This way charts can be made more interactive. Available Events are click, mouseover, mouseout and mousemove at dataSeries, dataPoints & legend. Here we are creating the chart object. I’ve excluded the data for a moment to focus on the type property, which determines the type of chart we want. Chart.js’ new Chart() constructor takes two parameters: Either a reference to a < canvas > element that the chart will be rendered on,
