问题
I have daily incident report which consist charts and incidents details.
When ever there is no data or incident the charts are left with blank in the report.
I want put a message in those block of charts.
Any body can help me in these.
Note : This issue is raised based on Chart display, if there is no data available instead of blank it should display the message.

Whereas you could make use of the regular "visibilty" property as suggested by Miki, there is also an out-of-the-box feature for handling this in charts:
You can see this example in action here: select a country which does not provide many economic data such "Andorra", and compare it with "Cayman islands": you would see this "No data" message in the second chart
