regl-scatter2d

[dy]

Work in progress, early stages. PR is for discussions.

• make proper creation of glcontainer and glcanvas
• make regl plot object
• setup parcoord, pointcloud and scatter to use regl plot
• make sure scatter updates are passing
• integrate
• 2 scattergl plots case
• shared context with parcoords case
• hi-precision mode Increased WebGL 2D projection precision - updated dependencies and mock #1114
• crossfilter case ?
• multiple plots
• shared regl context
• regl-scatter2d component
• clustering points (kdtree) for boosting hover
• scatter/scattergl image tests
• selection API for regl-scatter2d component handled by trace
• set proper name, remove scattergl
• sprite with all regular scatter symbols instead of font-atlas
• all FIXME/TODOs in code
• speed up autoscale
• background image scattergl image background feature request #1603 (comment) a separate PR
• wrong coloring Coloring for markers using scattergl isn't working properly #1909
• pointcloud/scatterregl two plots
• extra update after updateRange call for half-transparent lines
• point size discrepancy with scatter
• test memory use
• fills: tonexty, tonextx, tozerox, tozeroy
• multiselect Enable multiple selection for box/lasso tool #1853
• speed up hover (3 strategies) − on hold
• optimize creating select2d plot by cloning positions and unchangeble attribs
• reuse scatter2d tree for picking (can save up to 500ms for 1e6 points)
• subrange selection by the scatter2d tree (visible range + region)
• multiselect interaction: should persist selection on panning, zooming leave it for a separate PR
• all gl2d image tests
• jasmine tests help required @etpinard
• benchmark plot relayout/restyle test-case required @etpinard
• hover/pick modes
• entering selection mode in gl2d_12 respans axes
• make better pick
• running Plotly.plot(container, mock.data) two times breaks selection
• running Plotly.plot(container, mock.data) two times with modified data.type breaks selection and panning
• axes range detection discrepancy vs in gl2d_axes_labels, gl2d_axes_lines or gl2d_axes_range_type
• axis font size is broken in gl2d_axes_range_type
• gl2d_connect_gaps
• gl2d_date_axes
• gl2d_error_bars
• gl-line2d antialiasing vs reg-line2d it really depends on layout width, because some layouts are vv
• axes range in gl2d_scatter-colorscale-colorbar
• gl2d_stacked_coupled_subplots
• Make sure images are generated fine
• Merge master or slice by PRs? @etpinard
• Double click should remove selection
• Zoom of big number of points hides part of the points

@dfcreative I just added fill='toself' here #130 (comment) -- if it's ok with @etpinard, and if it's not too much of a time investment, could we add that to your TODO list here?

• SVG annotations on top of 2d webgl traces
• SVG shapes on top of 2d webgl traces

@dfcreative I just added fill='toself' here #130 (comment)

here's a few examples of toself:

• http://rickyreusser.com/plotly-mock-viewer/#scatter_fill_self_opacity

@bpostlethwaite that should work already.
@cpsievert@etpinard added toself logic, but seems that making hollow fills is a bit tricky in regl.

WebGL vs SVG

@bpostlethwaite SVG shapes and annotations:

@dfcreative Non-blocking for the first regl release, but it would be nice to make the visible: 'legendonly' state NOT clear the gl context to speed up trace visibility toggle via legend items.

Closing in favour of #2258
