Interp?,heatmap? instead of 'filled'
I have lon and lat and signal stengths plotting from my roaming GPS Lora module that reports signal strength to Thingspeak at it's location. I got GEOSCATTER plotting location circles.But i want extrapulate?Interp?Heatmap. the stengths between the points. When i use Interp i end up timiming out. How do i modify my code to do this?

Hey Andy,
I appreciate this discussion, and its an interesting topic for sure. I've used the scattered interpolant method for heatmaps in an example before, but I guess not on very large data sets.
You might consider asking MATLAB answers (menu above) in addition to here on the ThingSpeak discussion forum. You will get more MATLAB code help there I think. They might not be aware of ThingSpoeak timeouts, but they will be able to help optimize the analysis.
I suspect there is a MATLAB function or plot type that can provide the visualization you are looking for directly. You might also try asking the agent at the MATLAB playground. Its also pretty great at MATLAB, and mostly good at ThingSpeak.
You can also consider buying a paid license to get longer compute time.
If you find a good solution, please post it here if you can. Thanks!
