0 votes

the problem is that the rate of ploting is too slow which has the interval about 7 or 8 seconds. Is it possible to increase this rate?

also I can use the romote manager of digi device to display the data:


but in this website, it seems that it's not possible to draw a dynamic chart?

Thank you!

Perhaps you might have better responsiveness designing your own chart by extracting the data from the Device Cloud (the Heroku application shows code examples or you can reference the Device Cloud Programming Guide: http://www.digi.com/resources/documentation/digidocs/90002008/default.htm).

Also, keep in mind, Device Cloud throttling which can impact data latency and vary depending on the type of subscription:
