Chart Paddings & Margins
The following attributes help you control chart margins and paddings. Froala Charts allows you manually
customize the padding of various elements on the chart to allow advanced manipulation and control over chart
visualization. Padding in Froala Charts is always defined in pixels, unless the attribute itself suggests
some other scale (like plotSpacePercent, which configures the spacing using percentage values). You
can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom, left and
right of the chart. It's not necessary for you to specify any padding/margin values. Froala Charts
automatically assumes the best values for the same, if you do not specify the same.

Type: Number
Range: In pixels
The color Object and The colorRange Object
Attributes of the color object (child of the colorRange object) are used to define
ranges for dividing the gauge scale. Although the color object has to be defined within the
colorRange object, ranges cannot be collectively customized using the colorRange
object because it does not have any attributes of its own.

Type: Number
Range: 0 - 100
borderAlpha
Border alpha for the color range.

equal to the chart's lowerLimit and the minValue of the succeeding color range
should be equal to the current maxValue.

The dial object is used to create and configure dials for angular gauges. You can create as many
dials for your gauge as required. For each dial to be created, a separate dial object has to be
defined in the JSON data.
Although the dial object has to be defined within the dials object, dials cannot be
collectively customized using the dials object, because it does not have any attributes of its own.
These attributes let you create and customize dials for an angular gauge.
