The plot in my Simulink model scope doesn't match with ThingSpeak visualization.

Can you clarify what you mean by not matching? Are the data points completely different, or are there just a few missing, or something else?

Maybe you could share a screen shot to show us what you mean?

Hi Tanusree,

The issue might be due to one of the following:

Please check that the channel number is correct and the Read API Key you are providing is correct.
Please check the "Update period" field. It is used to set the time between successive reads over the channel.
Verify the "Sample Time" of the block as well if it is as per your requirement.

For more information, please follow the below documentation:

Hope it helps!!
