Contents of Channel Status Updates disappears

Hi,
my Channel Status Updates show the right data for a while. After a few hours without sending status data, the Channel Status Updates window becomes empty. Is this the intended behaviour? I would prefer to keep the data, even if it is a few hours old.

Is this true after refreshing the page? The channel status updates widget shows onlu the last 24 hours of status.
You could create a custom MATLAB visualization to display more.
Heres some code to show the last 8 results (may need some tweaking though)
url='https://api.thingspeak.com/channels/592680/status.json?results=8';
out=webread(url);
myTab=struct2table(out.feeds);
disp(myTab.(3));

I thnk the idea was to remove noise if you had a system that reports everytime (like the system on the channel in the code I shared.) Since there is a seperate status API, you can get the custom time frame or number of entries that you want, and there is less motivation for changing the status widget.
