v3.0.0-beta.21

Changes:

• Add trail mark type for variable-width lines.
• Add aspect property for image mark aspect ratio control.
• Add support for signals and null fields in comparator definitions.
• Add mark property config options based on role annotation.
• Add elBind parameter to View.initialize, to add bindings to a custom DOM element.
• Update custom symbol paths to scale size by radius, not diameter.
• Update signal bindings to populate an internal div element by default, rather than the top-level view container.
• Update vega-force to use current d3-force version.
• Fix protocol check bug that was breaking baseURL application in vega-loader.
• Fix canvas renderer sub-pixel damage region bug.

v3.0.0-beta.20

Beta release of v3.0.0-beta.20

Changes:

• Update legend layout to ignore x-axes, suppresses "jumpy" legend when axes change.
• Fix View.toCanvas typo bug.

v3.0.0-beta.19

Beta release of v3.0.0-beta.19

Breaking changes:

• Standardize naming for Vega spec, config and encode properties for axis ticks and labels: inclusion flags and encode blocks now all use the plural forms "ticks" and "labels". Note that "grid" and "title" properties remain singular and so are unchanged.

Other changes:

• Fix bounds calculation bugs.
• Fix vega-loader version in dependencies.

v3.0.0-beta.18

Beta release of v3.0.0-beta.18

Changes:

• Add support for "tooltip" encoding channel.
• Add custom tooltip handler support (View.tooltipHandler).
• Add support for axis and legend titles to use signal values.
• Add nulls-histogram and nulls-scatter-plot example specs to illustrate strategies for incorporating missing values into charts.
• Fix event preventDefault bug (resolves error in Firefox).
• Fix autosize calculation: limit one re-run per propagation cycle.
• Fix ViewLayout to enqueue changed axis/legend groups for render.

v3.0.0-beta.17

Beta release of v3.0.0-beta.17

Changes:

• Add bin-linear and bin-ordinal scales for handling binned data.
• Add sequence expression function (analogous to d3.range).
• Add deploy script for publishing Vega schema.
• Fix DOM element binding input reset bug.
• Fix subtle layout issues by having Bound transform always re-compute group bounds.
• Fix internal axis range calculation bug.
• Update autosize parameter to also accept object values ("autosize": {"type": "fit"})
• Add resize property to autosize objects to enable repeated automatic layout. Normally automatic layout is only performed upon initialization or when the width or height signal is modified. This leads to a more stable layout across other changes, which is typically the desired behavior. However, in some cases one might wish to re-size the view on all changes. To enable this behavior use "autosize": {"type": "...", "resize": true}.

v3.0.0-beta.16

Beta release of v3.0.0-beta.16

Breaking changes

• Move scale rangeStep property to a nested range.step property ("range": {"step": 20}).

Other changes:

• Add range scheme count to discretize color schemes for quantile and quantize scales ("range":{"scheme": "plasma", "count": 7}).
• Add support to include raw domain value arrays (or array-valued signals) in multi-domain scale definitions (For example: "domain": {"fields": [{"data": "table", "field": "foo"}, ["a", "b", "c"], {"signal": "values"}]})
• Update legend label formatting to show value ranges for quantile, quantize and threshold scales.
• Update example specs to track changes.

v3.0.0-beta.15

Beta release of v3.0.0-beta.15

Breaking changes:

• Use hyphenation (step-after) not camel-case (stepAfter) for interpolation curve names.
• Move scale "scheme" to an object-valued property of "range".
• Drop "index" scale, no longer needed with new scheme support.
• Update JSON configuration format: move config.mark.marktype blocks to config.marktype.
• Replace View.state with View.getState, View.setState methods.
• Migrate to use new "$schema" property.

Other changes:

• Add custom version of "sequential" scale to support piecewise domains.
• Add scale "interpolate" property for color space interpolation.
• Add scale "domainMid" property for simplifying diverging color ramps.

• Update legend entry and gradient methods to support interpolation.
• Suppress initial zero-sized legend symbols.
• Add "strokeDash" scale support to legends.
• Add treePath and treeAncestors hierarchy expression functions.
• Update hierarchy transforms to support configurable node key field.
