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.
There are two topics here:
1. Number of characters displayed in the "Output" window of a MATLAB Analysis or Visualization App page
2. Number of points to be visualized in a plot
The error message that is generated for your case is due to topic #1 - too many characters are being returned to the "Output" window.
Since I don't have your code, the general suggestion to resolve this error is to end your MATLAB commands with a semicolon ";". This prevents the LHS arguments from being printed to the "Output" window.
- Return characters to Output window
data = thingSpeakRead(12397)
- Do not return characters to Output window
data = thingSpeakRead(12397);
If this doesn't resolve the error, share your code and I might be able to find the cause of the error.
