ThingSpeak Channel Table Error
显示 更早的评论
Hi everyone,
I am having issues with my ThingSpeak Channel only displaying certain portion of my table. When I run the visualization code on its own, I get the full table as shown here:
However, when I refresh the page to check the ThingSpeak channel, only the last row of the table is displayed.
I have tried to adjust the Display Settings on the Visualization side, but I am still getting the same issue. I have attached my code to the bottom of this post for any clarity.
Any help would be appreciated!

hello i have a lot of trouble with this
time_space = 2000;
[data, timestamps, chInfo] = thingSpeakRead(readChannelID, 'Fields', [thickFieldID, co2FieldID], 'NumPoints', time_space);
and then need to extract the Nan data with e.g.
% Read Humidity Data humiditydata = data(:, 1); humiditydata = humiditydata(~isnan(humiditydata)); ilen = size(humiditydata);
with two array co2data humidity ect... size are different what is the max value?

%'DateRange',[startDate endDate]
myData= thingSpeakRead( readChannelID,...
'Fields', [3, 1],'DateRange',[startDate endDate]);
% Read Data other reading
disp(myData)
myData = thingSpeakRead( readChannelID,...
'Fields', [6, 1],'NumPoints',[12]);
disp(myData)
TString = evalc('disp(myData)');
TString = strrep(TString,'<strong>','\bf');
TString = strrep(TString,'</strong>','\rm');
TString = strrep(TString,'_','\_');
FixedWidth = get(0,'FixedWidthFontName');
% Output the table using the annotation command.
annotation(gcf,'Textbox','String',TString, ...
'Interpreter','Tex',...
'FontName',FixedWidth,...
'Units','Normalized',...
'Position',[0 0 1.5 1],'FontSize',7);

@frederic can you make a new post with your issue? It seems different than the OP.

I suggest using a timetable. The uitable element is really not right for ThingSpeak.
dataTimeTable = ...
thingSpeakRead(channelId, 'OutputFormat','TimeTable','NumPoints',3,'ReadKey',readAPIKey)
I did it for some traffic monitor data.
myCarData = thingSpeakRead( 38629,'numpoints',3,'outputFormat','TimeTable' );
TString = evalc('disp(myCarData)');
TString = strrep(TString,'<strong>','\bf');
TString = strrep(TString,'</strong>','\rm');
TString = strrep(TString,'_','\_');
FixedWidth = get(0,'FixedWidthFontName');
% Output the table using the annotation command.
annotation(gcf,'Textbox','String',TString,'Interpreter','Tex',...
'FontName',FixedWidth,'Units','Normalized','Position',[0 0 1.5 1],'FontSize',7);
I had to change the font size to get thigns to fit due to the long field names. You might be able to make that larger.
