ZingChart: Can I Add An Overlay With Text To The Chart

Its the internet you can do anything. Typically you will add a chart overlay to express to the user that data is not in the chart yet, data is loading or waiting to come back from the server.

No Data

We have a built in nodata object which you can populate when the chart has no data.

Dealing with No Data in a Feed

For charts using our feed feature we have another object called curtain to fill in the blank space on a chart that is found as data is loaded.  Try the example below to see it in action.

Custom Overlay

If neither of the two demos above fit your use case you can of course use native browser techniques to accomplish a chart overlay.
