uwdata/mosaic v0.9.0

on GitHub

Changelog:

Features:

• Breaking: Rename selection clause schema property to meta.
• Breaking: Change nearest interactor options to support multidimensional point selection and separate pointer targets from selected data channels.
• Add nearest interactor for selecting nearest 2D point.
• Add errorbarX and errorbarY marks for parametric confidence intervals over unaggregated data. The existing ruleX/Y marks should be used for pre-computed interval boundaries or custom aggregate expressions.
• Add mark-level select option for internal filtering of mark data, for example first or last points in a series or the current nearest mark to the pointer. Mark-level select simplifies creating various hover effects and annotations, though may query data in an unoptimized fashion, and does not interoperate with params or selections.
• Add covariance aggregate method.
• Add data cube support in cases where only some filtered clients are indexable.
• Add stddev, variance, covariance, and regression aggregates to data cube indexer.
• Add stddev, variance, covariance transforms in declarative specs.
• Add binning method hints for data cube indexer.
• Add selection clause generation methods (point, interval, etc).
• Add selection clause typings.
• Add Selection valueFor method to look up source-specific values.
• Add selection clause methods to inputs and interactors.
• Add value label to slider input.
• Add interval selection support to slider input.
• Add field option to inputs (menu, slider, search) to control the column referenced in selection clause predicates. (#406)
• Add toggleZ interactor directive to select line or area series using the z channel.
• Add QueryManager logQueries method to toggle logging of queries submitted to connector.
• Add FilterGroup index method to toggle data cube indexing.
• Add SQLExpression export to mosaic-sql package.
• Add Query.select column override support. Newer as values overwrite prior ones, and a null expression value removes any prior statements.

Examples:

• Add linear-regression-10m example with dynamic regression calculation over 10m points.
• Add athlete-height example with error bars and slider-based selection.
• Add line-multi-series example with interactive hover highlights and annotations.

Developer Support:

• Add options for logging and optimization to the dev (npm run dev) example runner.
• Add JSON schema publishing (e.g., to https://uwdata.github.io/mosaic/schema/latest.json).
• Add project vscode settings for YAML schemas (requires the YAML extension)

Bug Fixes, etc.:

• Fix bin transform to support extents for rule marks.
• Fix data type lookup in plot renderer.
• Fix SQL generation escaping of strings with single quotes.
• Fix Menu value initialization and updates. (#401)
• Fix legend interactor peers and selection value extraction.
• Fix interval 1D brush extent sort order.
• Fix raster mark color domain sorting.
• Fix data lookup from SVG in toggle and highlight interactors to support lines/areas.
• Update dependencies, documentation, and types.
