Part 1: Creating Simple Visualizations in ThingSpeak

By | March 9, 2020

ThingSpeak provides the following display types by default and these can be added using the corresponding buttons:

  • The gauge instrument and numeric display are called widgets. Press the “Add Widgets” button to add the widgets.
  • In the simplest case, more complex visualizations are used to display time histories in charts, where a quantity can be displayed as a time trace.
  • If these options are not sufficient, you can make use of MATLAB’s full range of powerful features. Fewer lines of code can be used to create appealing custom representations and even merge values from multiple channels. To add, press the “MATLAB Visualization” button.

After the ad has been added, it can be edited by clicking on the pen in the upper right corner and adapted to your personal preferences.

Numeric Display

The numerical display is the simplest and at the same time most accurate form of visualization of a single value.

The numerical format can be selected and the number of decimal places of the decimal value can be adjusted.


The pointer instrument can be used to display a value more descriptively. The value can be set in relation to target values or critical values via colour-coded areas. For example, you can see at a glance whether the value is “in the green range”.

This display contains more extensive configuration options: min/max value, additional display of the decimal value, interval of the axis labeling and the colored markings on the scale.


This diagram type is suitable for displaying the change of a value over time.

The configuration options are numerous and should not be described here in detail. You should try to find out which display best illustrates what you want to show.

    Hätte jemand einen Tipp zu Tutorials für die Datenaufbereitung in Thingspeak? Ich stecke da schon länger etwas fest.
