Variable radius legend #135
Conversation
Add import so that example runs
* Update text-size to use expression based on viz.label_size property
* Add new label properties to choropleth viz templates
* Move label properties to base class (leverage inheritance to reduce repeated arguments)
* Extract vector_color_map and numeric map (for height or line_width) to a VectorMixin class; fixes linestring bug with interpolation of color for certain color lookups with match-type
* Extend CircleViz with VectorMixin (start GraduatedCircleViz, HeatmapViz, ClusteredCircleViz)
* Extend vector data loading to base map and CircleMap -- datadriven styling for radius needs work
* Refine color mapping in VectorMixin and update templates, viz.py
* Update CircleViz template files with Jinja inheritance, establish {% block circle %} tag
* Update Vector layer example for CircleViz; add geojson_file_to_dict utility and logic to viz.py to facilitate loading data from JSON object, list of Python dicts, GeoJSON filename
* Refine function for parsing GeoJSON and JSON input (esp for vector visualizations) and add SourceDataError
* Add support for GraduatedCircleViz template to use vector source data layer
* Add support for HeatmapViz to use vector data source
* Add and refine tests; update utility name for geojson_to_dict etc.
* Change FileNotFoundError to IOError for Python2.7 support
* Enable data from vector layers to be used for data-driven style (without using data-join technique)
* Update docs for VectorMixin class, vector properties and label properties inherited from MapViz parent class
* Update geojson_to_dict to geojson_to_dict_list and add docs; organize MapBox.create_html()

Changes look good @akacarlyann - can you add a screenshot here for documentation and design 👀 showing what the new legend option looks like?
Another question - does this legend support a radius-and-color legend, for showing two dimensions using color and size for a graduated circle viz?
|
@ryanbaumann No multi-dimensional legends just yet, so the variable radius is using the |
|
Great. I'd anticipate that a user would expect both color and size options for a GraduatedCircleMap - I lean towards not merging this until we can incorporate both size and color into the legend. |
|
@ryanbaumann Makes sense to me to. Before this point only color legends were available for graduated circle visualizations. I think adding multiple sub-legends could parallel the multi-layer visualizations so I had expected that support to be wrapped in #129 but I'm happy to scratch out some ideas for this. |
|
@ryanbaumann is this more along the lines you were thinking? I still want to tackle compound/multi-variable legends in greater detail, but maybe this is a decent stand-in. Legends are taking up so much real-estate I want to look into adding a toggle to collapse them too. |
|
Yep, that looks great. I agree that legend real-estate is hard to manage - collapsable seems like a good option. |
|
Should I plan to merge this PR in, with a followup PR for collapsing the legends @akacarlyann ? |
|
@ryanbaumann I think I have a few commits locally to support the double graduated circle legend so I need to push those first. |
|
@ryanbaumann I'll see what I can do to clean up this PR this week :) |
…teLegendMargin functions in main.html to automatically place secondary legends
|
@ryanbaumann I added a couple functions to better automatically place a secondary legend, as in the case with the graduated circle default. I'm ready for review/merge when you are :) |
|
Still not seeing this functionality on GraduatedCircleViz, despite legends being displayed in the examples. Will this Merge resolve? |
|
@caerus-data it's ready for merge as of last week :) Glad it will be useful! @ryanbaumann the coveralls test looks like it stalled but I would hope this PR doesn't decrease coverage. |
|
Tightened up my issue. Will post as a new question |
Adds support for a variable radius legend for the GraduatedCircleViz. Adds legend_function parameter for selecting between calcColorLegend and calcRadiusLegend in JavaScript. Addresses #80.
