Am running multiple sensors in the field producing strings of data then sending them to a node. The node is an Arduino Uno on which SIM 800 is attached for internet connectivity. After computation, the result is several strings that i want to display to things speak. The code i have so far can only upload numerical data. Am in need of help to display these strings in Thingsspeak.Help me.

You can write string data to ThingSpeak just as you write numrical data. The automatic field plots wont show it, so you can write that string data to the status field, and enable the status display in your channel settings. Or create a custom MATLAB visualization to show the text read from any field.
To create the visualization, you can use thingSpeakRead, then figure, then the text function, or various other methods.
