ZingChart: Gauge dials and displaying values
In order to show the values of each dial, there are two separate methods. One is using a valuebox which displays the number near the dial itself. The issue with value boxes and gauge charts is that the other dials can get in the way and block the display of the value boxes. In general, the best way to display value boxes on gauge charts is to use:
valuebox: {
placement:"tip"
