Issues creating heatmap

[Casalex97]

Bug Report

The resulting map look like this:

Installation Method

Running survey with docker on Ubuntu 24.04.01

Actual Output

docker run -it --rm -v $(pwd):/pwd -w /pwd jantman/python-wifi-survey-heatmap:23429a4 wifi-heatmap secondoPianoWifiUffici2.4ghz

OUTPUT: /usr/local/lib/python3.9/dist-packages/scipy-1.8.1-py3.9-linux-x86_64.egg/scipy/interpolate/_rbf.py:266: LinAlgWarning: Ill-conditioned matrix (rcond=1.92779e-33): result may not be accurate. self.nodes = linalg.solve(self.A, self.di)

If useful I can upload the json file

Thanks for the support.

Wow! I've seen some strange heatmaps, but don't think I've seen this variety before.

The JSON file would probably be helpful.

Just to set expectations, I'm going to guess that the Ill-conditioned matrix (rcond=1.92779e-33): result may not be accurate. message might be related. Unfortunately, I don't understand the actual heat map code AT ALL; I got that from another project, and it's completely over my head.

This is the json file: secondoPianoWifiUffici2.4ghz.json

I'll try in the next days to do another survey in the same area.
