Chart presets
Throughout this tutorial, we have shown you how to create charts with Vizzu
using a chart type-agnostic, uniform way without being limited to a predefined
set of available charts. But sometimes, when you know the chart type you want to
use, it is easier to start with that and skip configuring it from scratch. For
this reason, Vizzu
provides preset chart configurations for many known chart
types. See the preset gallery for all available
presets.
Use the methods of the presets
static property of the Vizzu
class to build a
chart based on a preset. These methods return chart configuration objects that
can be passed to the animate
method. For example, this is how to create a
stacked bubble chart using its preset.
Info - How to setup Vizzu
In HTML
, create a placeholder element that will contain the rendered
chart.
<html>
<body>
<div id="myVizzu">
</div>
</body>
</html>
In JavaScript
, initialize and configure the chart:
import Vizzu from 'https://cdn.jsdelivr.net/npm/vizzu@0.7/dist/vizzu.min.js'
import data from 'https://lib.vizzuhq.com/0.7/assets/data/music_data.js'
let chart = new Vizzu('myVizzu')
chart.initializing
chart.animate({
data
})
chart.animate(Vizzu.presets.stackedBubble({
size: 'Popularity',
color: 'Kinds',
stackedBy: 'Genres',
title: 'Using a preset',
}))
Presets will override all channels, removing all previously set series from the
chart. Using a preset will also explicitly set most chart configuration
parameters. Exceptions to this are the legend
, title
, reverse
, and sort
properties that can be set while using a preset. Here's an example of a preset
where chart elements are sorted by value.
chart.animate(Vizzu.presets.radialStackedBar({
angle: 'Popularity',
radius: 'Genres',
stackedBy: 'Kinds',
sort: 'byValue',
title: 'Set sorting for a chart preset'
}))
As you will see, the preset doesn't override the previously configured sorting and wouldn't affect the rest of the chart config parameters mentioned above either.
Presets will affect chart configuration, but you might also want to set the style or the underlying data. In this case, you can use the more verbose syntax below, explicitly passing the preset to the 'config' property of the animate method's parameter.
chart.animate({
config: Vizzu.presets.radialBar({
angle: 'Popularity',
radius: 'Genres',
title: 'Setting style for a preset'
}),
style: {
'plot.xAxis.interlacing.color': '#ffffff00'
}
})
Info
You can also access presets via a chart
promise, for example
Vizzu.presets.radialBar
is equivalent to
chart.constructor.presets.radialBar
.
