Show traffic light on count 0 (handle no results)

[joydragon]

If you need to show green or red light on count 0 you can add the following code to the parameter definition:

handleNoResults: true

That leaves the code like this:

params: {
        defaults: {
          width: 50,
          redThreshold: 20,
          greenThreshold: 80,
          redAndGreenOnly: false,
          invertScale: false,
          rotateHorizontaly: false,
          handleNoResults: true
        },
        editor: require('plugins/traffic_light_vis/traffic_light_vis_params.html')
      }

Do you want me to add documentation?
(sorry - a bit out of focus on this project...)

It would be nice to have that as on option on the visualization itself (like the invert scale or rotate), or to set it as a default for this visualization so every time it gets 0 you can handle it accordingly
