Indicating missing data points as an error

I want to indicate heath of system via the data coming into telemetry. If the data is not coming in within the evaluated time then the graph ( preferably Stats) should change colour to red and show label like Need Attention. I have tried this with Value mappings but the graph only shows a data gap and does not indicate error for missing data points. Is it possible to fix this via this graph or is there a another alternative.
