Hi,
I am working on machine vibration and temp data. For this, I am using a vibration sensor(https://store.ncd.io/product/iot-long-range-wireless-vibration-and-temperature-sensor/)
and esp32(https://store.ncd.io/product/esp32-iot-wifi-ble-module-with-integrated-usb/) and I am able to view vibration and temp readings at ThingSpeak. Can you suggest me how to plot a graph for 3 different data using Matlab Visualization?

Nice application for ThingSpeak, thanks for sharing!

There are many suggestions on the visualization page of the documentation:
https://www.mathworks.com/help/thingspeak/visualize-data.html

Here is one example for plotting three days of weather data on the same axis:

You should also have a look at the Preventive Maintenance toolbox (PMT). Here is a demonstration using the PMT on vibration data from the fan in ThingSpeak.
