New Spline Charts for IoT Data Visualizations 3

Posted by Hans Scharler,

Once your data gets into ThingSpeak, you than want to do something with it. A first step is to see the data. If the data are sensor values from a Nest thermostat for example, then you want to see it as a chart. We added a new way to visualize your data by adding Spline Charts! Spline Charts are super easy to create with ThingSpeak, just add “type=spline” to your ThingSpeak Chart API call. (And of course, once you have it as a chart, you may want to embed it on our ioBridge Dashboard application.)

Here’s what the new Spline Chart looks like:

Here’s a regular line chart:

And just as a reminder, here are all of the supported ThingSpeak Chart types:

  • type=bar
  • type=column
  • type=line
  • type=spline
