|
|
<p>While chart types provide settings to configure the styling of each dataset, you sometimes want to style <strong>all datasets the same way</strong>. A common example would be to stroke all of the bars in a bar chart with the same colour but change the fill per dataset. Options can be configured for four different types of elements: <strong><a href="#arc-configuration">arc</a></strong>, <strong><a href="#line-configuration">lines</a></strong>, <strong><a href="#point-configuration">points</a></strong>, and <strong><a href="#rectangle-configuration">rectangles</a></strong>. When set, these options apply to all objects of that type unless specifically overridden by the configuration attached to a dataset.</p>
|
|
<h2 id="global-configuration">Global Configuration</h2>
|
|
<p>The element options can be specified per chart or globally. The global options for elements are defined in <code>Chart.defaults.global.elements</code>. For example, to set the border width of all bar charts globally you would do:</p>
|
|
<pre><code class="lang-javascript">Chart.defaults.global.elements.rectangle.borderWidth = <span class="hljs-number">2</span>;
|
|
</code></pre>
|
|
<h2 id="point-configuration">Point Configuration</h2>
|
|
<p>Point elements are used to represent the points in a line chart or a bubble chart.</p>
|
|
<p>Global point options: <code>Chart.defaults.global.elements.point</code></p>
