D3fc plugin #498

…skip_headers and merge into templated get_data

The modified d3fc axis component is likely to look mostly like this. The multi-axis component may or may not make it into d3. We split the axis into multiple levels in Perspective code, then give that information to the multi-axis

Shape also has to be displayed in the legend

2 types of legend - colour (categories) and symbol (shape and colour) Moved filter functions to their own module

…ng css

* Apply XY point colour based on mainValue * Add colourRangeLegend to XY chart with colour range * Use newer colourRangeLegend for Heatmap legend and scale

* Set back to reference "cjs" dependency, with yarn focus This change requires the use of `yarn install --focus" in the perspective-viewer-d3fc folder, if you're only compiling the plugin (so that the dependency with the /cjs folder is pulled in locally) * Update to work without global install webpack Must pick webpack 3.5.6 when doing `yarn install --focus` * Silence webpack error relating to "@d3fc/d3fc-data-join" reference

Only currently works for continuous scales (i.e. time series)

The problem occurred because we filtered out empty values from the grouped series data, leading to a different ordering when the data was re-combined for the domain. Instead, we can keep the empty values in as 0 (or baseValue + 0)

…ols.js) - also, reduce padding on y_scatter

… from to_format()

Get x/y range from plot-area "measure" event Use a generic approach (similar to mainAxis) for getting closest point Added option to existing tooltip component to allow for always-show Added tooltips for canvas scatter chart

New approach to setting xAxis/yAxis lead to a slightly different method for styling the axis too.

The d3fc chart replaces the axis `decorate` function with its own `xDecorate` function, so we need to set that directly.

* Removed old SVG X/Y chart and replace with the Canvas one * Remove old pointSeries

Replaced use of Array.flat "Fixed" `withoutOpacity` function so that it uses "rgb()" instead of "rgba()" Added workaround for weird Edge issue that doesn't render the plot-area of some charts (bar/column charts and heatmap) unless you resize the window. An immediate redraw of the D3 element seems to work, but is not great.

It turns out we don't actually need to use copies of the scales, and therefore can avoid decorating the chart object to get the "measure" (though this approach does require calling the "toolTip" component after the chart has been rendered. This allows us to simplify the code quite a lot. Also: * rebind `settings` and other properties from base tooltip component * added `size` option for controlling highlight sizing (though the "range" has to be modified because the symbol size behaviour isn't the same as the circle radius behaviour) * Use nearby-tooltip for the y-scatter chart, since it's a better experience

…eys_cropped legend draggable and keys cropped

Refactored shared svg/canvas gridlines

Switched ohlc and candlestick charts to canvas

For ordinal scales the bars have inner and outer padding to offset them, and should also be left-aligned to draw them in the right place. For non-ordinal scales without the padding, the alignment should be left at the default.

Implemented fix for missing final date value

* Added bollinger bands and moving average to candle/ohlc Also reorganised the seriesColor stuff to make it a bit more reusable * Moved ohlc/candle series into its own module Also support for only one `mainValue`, by getting the `closeValue` from the next day's `openValue`. The bollinger stuff is based off the `openValue` anyway.

Reused tooltip code to extract relevant name-value data for currently selected node. Added source row object to each data element so it can be sent back up in the event. Added "filter" information to the settings so it can be included in the event.

Implemented selection events from d3fc plugin

Initialise by briefly creating svg elements to get the css styles for all series. Then use those styles for the colour ranges. Colour ranges now always have a default, so no need to fall back on hard-coded or un-styled. Get "opacity" level (for fill areas etc) from the base "series" setting, so it can be applied at runtime. This allows the themes to set different opacity levels.

Used a html template rather than reproducing similar files for each. Included themed version of one chart (bar) Excluded OHLC and Candlestick because the simple_tests data is not suitable Updates to results.json
