How to display the field graph across the entire width of the screen?

And not just a small ThingSpeek visualization graf on the computer screen.

Answer 1

The attached html file calls data from Thingspeak and displays it on a webpage which you can resize.

The only line you need to change starts with '<iframe'

Change:

channels (currently 849131) - to yours

charts (currently 1) to your field number

api_key (currently staring FYJP.....)

results= (currently 300) to however many samples you need.

There are lots of other parameters you can play with. This is a brilliant facility as you can add more iframes for different field numbers and/or channels

Hope this helps

Thank you. I tried it and it works ;-). But this need manually change date and y axis range. I thought thingspeak.com can maximize the chart to full screen automaticaly.

You can click the small icon on the individual window (looks like an arrow popping up and out of a window) to pop it out to its own tab. Then, edit the URL in the browser to specify the desired size of the window. Now you can bookmark this URL in your browser.

Answer 2

This feature is full of options. This is an extract from a system where I dynamically change the date/time to go back and forward in days.

Have now deleted "&start=2020-03-15 00:00:00&end=2020-03-16 00:00:00" and the axismin/axismax

Is this new one better? It now shows the last 300 readings. (My sampling is every 5 minutes so gives just over 24 hours) .

Hover over the last setting and you will see it is real time.

hFig = figure; % Bring up new figure.
plot(x, y);
hFig.WindowState = 'maximized';

How to insert above code into chart options? See

Chart is here

[Image Analyst]

I don't know what that is. But if you plotted your data with plot() onto a figure, then my code should maximize the figure window.

@ Image Analyst: Thank you, your 2 code lines

hFig = figure; % Bring up new figure

....

hFig.WindowState = 'maximized';

work - in a Matlab Visualization created under Thingspeak | Apps.

@ Dan: For the standard Thingseak plots, which are edited as shown in your screen shot, I haven't found any way to add any code.
