Properties in Chart.defaults.global contain configuration options for all types of charts, including graphical elements, titles and captions, layout properties, animation, tooltips, events, and plugins. But it doesn't include grids and scales, which are configured in the Chart.defaults.scale object. The options available in Chart.defaults.global are listed as follows. All these properties, except the default font and color settings, are also available as properties in the options configuration object of any chart instance:

Object	Value	Description
`defaultColor`	CSS color	The default color for all chart elements. This property is overriden in several chart elements, so it's not really very useful. The default is `'rgba(0,0,0,0.1)'`.
`defaultFontColor`	CSS color (examples: `'lightblue'`, `'#9cf'`, `'#ff0000'`, `'rgb(100%,50%,25%)'`, `'hsl(60,100%,50%)'`, `'rgba(100%,50%,25%,0.6)'`, `'hsla(60,100%,50%,0.1)'`)	The default color for all text (unless overridden with a more specific font color property). The default is `'#666'`.
`defaultFontFamily`	CSS font-family name or list (example: `'Helvetica`, `"Helvetica Neue"`, `sans-serif'`)	The default family for all text (unless overridden with a more specific font color property). The default is `'Helvetica Neue'`, `'Helvetica'`, `'Arial'`, `sans-serif`.
`defaultFontSize`	Font size in pixels	The default size in pixels for all text (unless overridden with a more specific font size property). The default is 12.
`defaultFontStyle`	CSS font-style (ex: `'bold'`, `'italic'`, `'normal'`) or any style available with the font that is being used (ex: `'condensed bold'`, `'light'`, and so on)	The default style for all text (unless overridden with a more specific font style property). The default is `'normal'`.
`layout.padding`	The number or object with numerical properties for `top`, `left`, `right`, `bottom`	If the value is a number, the padding in pixels is applied to all sides of a chart. If it's an object, the individual values can be applied to different sides of the chart.
`maintainAspectRatio`	`true` or `false`	Maintains the aspect ratio of the canvas element.
`responsive`	`true` or `false`	Resizes the chart when the canvas is resized. The default is `true`.
`showLines`	`true` or `false`	If `true`, shows lines between point values. Default is `true`, but is overridden to `false` in scatter charts.
`title`	Object	See the Legends and labels section in this chapter.
`legend`	Object	See the Legends and labels section in this chapter.
`tooltips`	Object	See Chapter 7, Advanced Chart.js.
`hover`	Object	See Chapter 7, Advanced Chart.js.
`elements`	Object	See the Chart elements section in this chapter.
`events`	Object	See the Animation section in this chapter.
`plugins`	Object	See Chapter 7, Advanced Chart.js.
`animation`	Object	See the Animation section in this chapter.

Configurable options in Charts.defaults.global that can be configured for all charts. Callbacks are not listed.

For example, the following configuration will turn off-line rendering between value points for any charts. Since this property is not overridden in line or radar charts, if you create a line chart, it won't have any lines. Only the points will be visible:

Chart.defaults.global.showLines = false;

This other configuration will turn off the legends for all charts (very useful for single-dataset charts):

Chart.defaults.global.legend.display = false;
