Imagine we have a chart we populate via an AJAX request of seven years worth of data in array of array format. While that data is being fetched we might as well display a nice picture for the user using the noData object like so
noData : {
text:'Waiting For AJAX request',
fontSize:22,
backgroundImage:'https://i.giphy.com/ONk787QkAmAZq.gif'
}
Example: https://demos.zingchart.com/view/MH9CZ11W
Note: We purposefully timed this request to show the noData value. Loads shouldn't be this slow.
