d3plus-plot

A reusable javascript x/y plot built on D3.

Installing

If using npm, npm install d3plus-plot. Otherwise, you can download the latest release from GitHub or load from a CDN.

1import modules from "d3plus-plot";

d3plus-plot can be loaded as a standalone library or bundled as part of D3plus. ES modules, AMD, CommonJS, and vanilla environments are supported. In vanilla, a d3plus global is exported:

1<script src="https://cdn.jsdelivr.net/npm/d3plus-plot@1"></script>
2<script>
3  console.log(d3plus);
4</script>

Examples

Live examples can be found on d3plus.org, which includes a collection of example visualizations using d3plus-react. These examples are powered by the d3plus-storybook repo, and PRs are always welcome. :beers:

# new Plot()

Creates an x/y plot based on an array of data.

# Plot.annotations(annotations) <>

Allows drawing custom shapes to be used as annotations in the provided x/y plot. This method accepts custom config objects for the Shape class, either a single config object or an array of config objects. Each config object requires an additional parameter, the "shape", which denotes which Shape sub-class to use (Rect, Line, etc).

Additionally, each config object can also contain an optional "layer" key, which defines whether the annotations will be displayed in "front" or in "back" of the primary visualization shapes. This value defaults to "back" if not present.

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.axisPersist([value]) <>

Determines whether the x and y axes should have their scales persist while users filter the data, the timeline being the prime example (set this to true to make the axes stay consistent when the timeline changes).

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.backgroundConfig([value]) <>

A d3plus-shape configuration Object used for styling the background rectangle of the inner x/y plot (behind all of the shapes and gridlines).

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.barPadding(value) <>

Sets the pixel space between each bar in a group of bars.

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.baseline(value) <>

Sets the baseline for the x/y plot. If value is not specified, returns the current baseline.

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.buffer([value]) <>

Determines whether or not to add additional padding at the ends of x or y scales. The most commone use for this is in Scatter Plots, so that the shapes do not appear directly on the axis itself. The value provided can either be true or false to toggle the behavior for all shape types, or a keyed Object for each shape type (ie. {Bar: false, Circle: true, Line: false}).

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.confidence(value) <>

Sets the confidence to the specified array of lower and upper bounds.

This is a static method of Plot, and is chainable with other methods of this Class. Can be called with accessor functions or static keys:

1       var data = {id: "alpha", value: 10, lci: 9, hci: 11};
2       ...
3       // Accessor functions
4       .confidence([function(d) { return d.lci }, function(d) { return d.hci }])
5
6       // Or static keys
7       .confidence(["lci", "hci"])

# Plot.confidenceConfig([value]) <>

If value is specified, sets the config method for each shape rendered as a confidence interval and returns the current class instance.

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.discrete(value) <>

Sets the discrete axis to the specified string. If value is not specified, returns the current discrete axis.

This is a static method of Plot, and is chainable with other methods of this Class.

# Plot.discreteCutoff(value) <>

When the width or height of the chart is less than or equal to this pixel value, the discrete axis will not be shown. This helps produce slick sparklines. Set this value to 0 to disable the behavior entirely.

Sets the pixel space between groups of bars.

This is a static method of Plot, and is chainable with other methods of this Class.
