# 副标题

默认情况下,副标题是位于主标题下方的第二个标题。 它具有与主 title 完全相同的配置选项。

Subtitle is a second title placed under the main title, by default. It has exactly the same configuration options with the main title.

# 副标题配置

命名空间: options.plugins.subtitle. 字幕的全局默认值在 Chart.defaults.plugins.subtitle 中配置。

Namespace: options.plugins.subtitle. The global defaults for subtitle are configured in Chart.defaults.plugins.subtitle.

title 完全相同的配置选项可用于字幕,只是命名空间不同。

Exactly the same configuration options with title are available for subtitle, the namespaces only differ.

    options: {
        plugins: {
            subtitle: {
                display: true,
                text: 'Custom Chart Subtitle'
            }
        }
    }
});
