I have some excpetional cases that say: I need to show the charts that have data and when it doesn't have any records to show, I need to show like "No Data" image or at least show a message above this graph saying: No data to dispaly. Is there a way to implement this. Not pretty sure if I can do this using R lang, I barely know how to use R so please feel free to suggest as I need this feature so badly.
