Fonts

There are 4 special global settings that can change all of the fonts on the chart. These options are in Chart.defaults.global. The global font settings only apply when more specific options are not included in the config.

For example, in this chart the text will all be red except for the labels in the legend.

  1. Chart.defaults.global.defaultFontColor = 'red';
  2. let chart = new Chart(ctx, {
  3.     type: 'line',
  4.     data: data,
  5.     options: {
  6.         legend: {
  7.             labels: {
  8.                 // This more specific font property overrides the global property
  9.                 fontColor: 'black'
  10.             }
  11.         }
  12.     }
  13. });

Non-Existant Fonts

If a font is specified for a chart that does exist on the system, the browser will not apply the font when it is set. If you notice odd fonts appearing in your charts, check that the font you are applying exists on your system. See issue 3318 for more details.
