Attempted to plot 3 days worth of 5 minute data (https://thingspeak.com/apps/matlab_visualizations/89640) but the matlab visualisation gives the following error:-
ThingSpeak cannot display the amount of data requested. Reduce the size of the output or suppress the output with a semicolon.
I calculated that 5 min data for 3 days should only be 864 points.
What is the limit? Less than 1000 data points doesn't seem very generous.
