A gauge with a dial. All options can be found in the Google documentation. Gauge charts are useful when you want to measure how values are performing against specific reference numbers. For example, we at Scandio use Gauge charts in our Confluence to visualize the success factors of our software projects. Very useful!

Expected InputFormat

The input data for Gauge charts need to be a table with 2 columns:

  • Column 1: Label that will be displayed in the middle of the chart

  • Column 2: Value that will be pointed at by the needle

If the dataset contains multiple rows, multiple Gauge charts will be displayed. The first row, the table headers, are ignored.

Coloring And Configuration Ticks

This Gauge has colored areas and labeled ticks.

PocketQuery.chart('Gauge', {
   dataTable: [['Month', 'Value'], // adding dummy data for testing; remove this attribute for productive use
        ['JAN-17', 52.1],
        ['FEB-17', 81.2],
        ['MAR-17', 71.7]],
  width: 600,          // setting size of resulting area that includes ALL charts drawn
  height: 350,
  max: 100,           // setting max value (highly depends on data to be displayed)
  majorTicks: ['0%','20%','40%','60%','80%','100%'],   // setting labels of the major ticks; they will be distributed evenly
  minorTicks: 4,
