Trigger dashboard notification based on chart data from .txt

Hi so I am having an issue; I want a notification to appear on my dashboard based on the result on my chart.

For example, if my total on my chart is above 42, a notification to be triggered.

Here is my flow, please let me know if additional data is needed:

Welcome to the forum.

Don't attempt to do it based on what is on the chart, do it based on what is going into the chart. If you feed whatever it is that you want to check for >42 into a Switch node then you can get it to pass the message on whenever it is >42 and ignore any messages with the value <=42.
