Starting in MATLAB R2022a, use the append option in exportgraphics to create GIF files from animated axes, figures, or other visualizations.

This basic template contains just two steps:

% 1. Create the initial image file
gifFile = 'myAnimation.gif';
exportgraphics(obj, gifFile);

% 2. Within a loop, append the gif image
for i = 1:20

      %   %   %   %   %   %    % 
      % Update the figure/axes %
      %   %   %   %   %   %    % 

      exportgraphics(obj, gifFile, Append=true);
  end

Note, exportgraphics will not capture UI components such as buttons and knobs and requires constant axis limits.

I have both of my account profile and channel export time zones set to "(GMT+8000)Beijing". The datetime from the exported feeds.csv looks like:

'2021-09-06 11:16:28 CST'

I want to import data, but MATLAB do not directly understand its datetime format. I assume "CST" to be "China Standard Time", but when I try to convert it to datetime, MATLAB throws an error:

 >> datetime(s,'InputFormat',"yyyy-MM-dd HH:mm:ss z","TimeZone","Asia/Shanghai","Locale","zh_CN")
 Error using datetime (line 651)
 Unable to convert '2021-09-06 11:16:28 JST' to datetime using the format 'yyyy-MM-dd HH:mm:ss z' and locale 'zh_CN'.

However if I change the "Locale" to US instead:

>>datetime(s,'InputFormat',"yyyy-MM-dd HH:mm:ss z","TimeZone","Asia/Shanghai","Locale","en_US")
ans = 
    datetime
07-Sep-2021 01:16:28

There is no error, but the time is wrong and is 14 hours ahead. So I guess that MATLAB sees this "CST" as "Central Standard Time".

My point is:

1. It's pretty strange that the datetime exported by ThingSpeak could not be directly understood by MATLAB. MATLAB is supposed to work with ThingSpeak data seamlessly, but now I have to find a detour to import ThingSpeak data to MATLAB.
2. It seems that the datetime function needs improvement to understand this "CST" timezone, or that ThingSpeak could improve its datetime output format.

Hello everyone. Yesterday i started my project and now im trying to export data files (CSV) but it is empty. It cointains just the headers and last read (i think). Anyone knows what is happening?

Example CSV exported created_at,entry_id,field1,field2,field3,latitude,longitude,elevation,status 2021-05-26 19:39:23 -03,1,25.00,"43.00

",,,,, 2021-05-26 19:39:39 -03,2,24.80,40.00"

Hi,

I would like to export data from my channel. My channel receives data every 15 minutes but I would like to export the data similar to what I can see when I change the chart/field's timescale to 60 minutes.

Thanks!
