Gauges are a great way to quickly visualize and increase comprehension of the data shown on your DAKboard screens. Read on to learn more!
Gauges are easy to setup in a DAKboard custom screen. Click the “Add a block” button, then select the “Gauge” block type under the Charts, Graphs & External Data section:
Edit the block, and you’ll see two data source options:
- Local: Allows you to enter the gauge value directly in the DAKboard settings
- Remote (JSON fetch): Pulls the gauge value from a remote JSON feed URL at the desired interval
Select the desired option and add the corresponding info (JSON URL, credentials, etc.) if needed. Lastly, if the gauge data is not a percentage, add optional min and max values so the value will be scaled properly. Save your changes, preview the screen and you’ll see the basic gauge on your screen:
In classic DAKboard fashion, we’ve added a few ways for you to customize the look of the gauge even further.
Add a Title
Simple add some text in the title field under the “Options” section when editing the block to add a title to the gauge:
Show the Actual Gauge Value
Under the “Formatting” tab, you’ll see an option to show the value as a percentage or the raw value. Select “value” to show the raw value:
Add some Color Coding
Using the “Rules” tab is a great way to add some color coding to the gauge. In this example, low memory usage will show green, and high memory usage will show red:
… which will result in gauges that would look like this:
Any valid HTML color code or name can be entered into the gauge color box in the Rules tab. There’s a great list of color names here. You can also change the background color based on the gauge value as well.
