Thingsspeak : How to add multiple graphs in single field Ex: Real time monitoring 30 machines temperature in single graph (filed1) Thingsspeak : How to add multiple graph in single field ex: monitor 30 machine temparatre in single graph You have a lot of options. Much of how you choose to plot it depends on your timestamps. In this example for <https://www.mathworks.com/help/thingspeak/Compare-Temperature-Data-from-Three-Different-Days.html temperature for three different days> , I had to do some extra work to play the different time stamps on the same x axis. If all the time stamps are the same or at least in a similar range, you can more easily plot them all by calling hold; after the first plot command, and then call successive plot commands for each plot you want to add. You can also use the <https://www.mathworks.com/help/matlab/ref/tiledlayout.html?searchHighlight=tiledlayout&s_tid=srchtitle tiled layout> to stack plots, but for 50 machines, the plots would be come very tiny. Since MATLAB has a lot of computational power built in, I would recommend you develop a custom plot type. Perhaps calculate the mean of all 50 machines and then only plot a machine if it is within some standard deviations of the mean, for example. Good luck, please share your final plot if you can. thingsspeak dashboard
