Displaying telemetry data in mission planner in real time

I am working on a fixed wing plane in which the telemetry data needs to be displayed in real time and at least in one inch font. Does anyone have advice for how to accomplish this in mission planner or how to a run a script simultaneously with mission planner to accomplish this? Thank you in advance for any feedback.

what information needs to be displayed? you could look into iron python scripting, and create a very basic form and display values in any size font you want.

The altitude data needs to be displayed whenever a drop is performed (activating a servo). Specifically, I am concerned with displaying the altitude data corresponding with servo activation on channels 9-12. I will also look iron python scripting, thank you.
