hello dear
I working on a power system by Matlab simulation and all results of my project contains x-axis values and Y-axis values and I want to display these results on Thingspeak, but the problem of Thingspeak has displayed only the y-axis with time (date) in the x-axis.
for example, I have two values:
The X-axis represents the number of iteration (100, 200, 300, 400, 500)
The Y-axis represents the power values (2kw, 3 kW, 3.5kW, 1kw, 0.5kW)
please how can display the result of Matlab workspace in Thingspeak?
How disply the result in down image in Thingspeak field?
please reply
Best Regards

You can use the MATLAB visualizations app to generate this visualization. Write your data to two consecutive fields in a channel with any timestamp you wish. If you put the data in a table and then a timetable, this will make it easiest to write to ThingSpeak.
In a MATLAB visualization (in ThingSpeak), use the ThingSpeakRead() function to get the data into MATLAB. Use the scatter or plot command on the two fields of interest. This example shows a similar workflow where you can plot two non -time variables.
