You could use the charts API to send a particular field chart. You wont get the custome MATLAB visualizations this way though.
Write MATLAB analysis code that generates the appropriate link and then trigger an alert email to send it to yourself. Here is part of an example, you'll have to modify it yourself with the right parameters.
myAverage=3;
url=sprintf("https://api.thingspeak.com/channels/276330/charts/1?average=%d&days=7&min=200",myDays);
alertBody="your link is " +url; %or you could add html fomatting to make sure it is clickable
webwrite(alertUrl , "body", alertBody, "subject", alertSubject, options);
To do it with custom MATLAB visualization plot, you could generate an image of your plot and then save it to amazon s3 or dropbox and email yourself a lnk to the plot. Thats a bit more involved, but Ive done all the parts of that workflow seperately. EDITED: I'd stick with version 1 for now. Or just make a custom MATLAB visualization, put it on a channel view and email yourself the link to the channel everyday. :)
