v0.4.1 (2024-10-31)

Fixed

• Properly handle :zoomable option in Tucan.Finance.candlestic/7 and other multi-layer plots.
• Remove :zoomable option from plots with non quantitative scales since this is not supported by vega-lite.

v0.4.0 (2024-10-21)

Added

Plots

• Add Tucan.range_bar/4 plot

data = [
  %{category: "A", min: 28, max: 55},
  %{category: "B", min: 43, max: 91},
  %{category: "C", min: 13, max: 61}
]

Tucan.range_bar(data, "category", "min", "max", fill_color: "red")

{"$schema":"https://vega.github.io/schema/vega-lite/v5.json","data":{"values":[{"category":"A","max":55,"min":28},{"category":"B","max":91,"min":43},{"category":"C","max":61,"min":13}]},"encoding":{"x":{"field":"min","type":"quantitative"},"x2":{"field":"max","type":"quantitative"},"y":{"axis":{"labelAngle":0},"field":"category","type":"nominal"}},"mark":{"color":"red","fillOpacity":1,"type":"bar"}}

• Add Tucan.Finance.candlestick/7 specialized plot

Tucan.Finance.candlestick(:ohlc, "date", "open", "high", "low", "close",
  width: 400,
  tooltip: true,
  fill_opacity: 0.5
)

{"$schema":"https://vega.github.io/schema/vega-lite/v5.json","data":{"url":"https://vega.github.io/editor/data/ohlc.json"},"layer":[{"encoding":{"x":{"field":"date","type":"temporal"},"y":{"field":"low","scale":{"zero":false},"type":"quantitative"},"y2":{"field":"high","type":"quantitative"}},"mark":{"fillOpacity":0.5,"tooltip":true,"type":"rule"}},{"encoding":{"color":{"condition":{"test":"datum.open < datum.close","value":"#06982d"},"value":"#ae1325"},"x":{"field":"date","type":"temporal"},"y":{"field":"open","scale":{"zero":false},"type":"quantitative"},"y2":{"field":"close","type":"quantitative"}},"mark":{"fillOpacity":0.5,"tooltip":true,"type":"bar"}}],"width":400}

• Add Tucan.Geometry.ellipse/5

Tucan.layers([
  Tucan.Geometry.ellipse({0, 0}, 5, 3, 0, line_color: "green"),
  Tucan.Geometry.ellipse({2, 2}, 4, 1, 40, line_color: "red")
])
|> Tucan.Scale.set_xy_domain(-7, 7)

{"$schema":"https://vega.github.io/schema/vega-lite/v5.json","layer":[{"data":{"sequence":{"as":"theta","start":0,"step":0.1,"stop":361}},"encoding":{"order":{"field":"theta"},"x":{"field":"x","scale":{"domain":[-7,7]},"type":"quantitative"},"y":{"field":"y","scale":{"domain":[-7,7]},"type":"quantitative"}},"mark":{"color":"green","fillOpacity":1,"strokeOpacity":1,"strokeWidth":1,"type":"line"},"transform":[{"as":"x","calculate":"0 + cos(datum.theta*PI/180) * cos(0*PI/180) * 5 -sin(datum.theta*PI/180) * sin(0*PI/180) * 3"},{"as":"y","calculate":"0 + cos(datum.theta*PI/180) * sin(0*PI/180) * 5 +sin(datum.theta*PI/180) * cos(0*PI/180) * 3"}]},{"data":{"sequence":{"as":"theta","start":0,"step":0.1,"stop":361}},"encoding":{"order":{"field":"theta"},"x":{"field":"x","scale":{"domain":[-7,7]},"type":"quantitative"},"y":{"field":"y","scale":{"domain":[-7,7]},"type":"quantitative"}},"mark":{"color":"red","fillOpacity":1,"strokeOpacity":1,"strokeWidth":1,"type":"line"},"transform":[{"as":"x","calculate":"2 + cos(datum.theta*PI/180) * cos(40*PI/180) * 4 -sin(datum.theta*PI/180) * sin(40*PI/180) * 1"},{"as":"y","calculate":"2 + cos(datum.theta*PI/180) * sin(40*PI/180) * 4 +sin(datum.theta*PI/180) * cos(40*PI/180) * 1"}]}]}

Other

• Support zoom and pan with mouse in all plots. You can use your mouse to zoom and pan most plots if :zoomable option is set to true. You can also reset the view with a double click.

Tucan.scatter(:iris, "petal_width", "petal_length", zoomable: true)

{"$schema":"https://vega.github.io/schema/vega-lite/v5.json","data":{"url":"https://gist.githubusercontent.com/curran/a08a1080b88344b0c8a7/raw/0e7a9b0a5d22642a06d3d5b9bcbad9890c8ee534/iris.csv"},"encoding":{"x":{"field":"petal_width","scale":{"zero":false},"type":"quantitative"},"y":{"field":"petal_length","scale":{"zero":false},"type":"quantitative"}},"mark":{"fillOpacity":1,"type":"point"},"params":[{"bind":"scales","name":"_grid","select":"interval"}]}

• Add Tucan.Export wrapper around VegaLite.Export
• Add Tucan.Axes.set_color/2, Tucan.Axes.set_color/3 helpers.
• Add Tucan.Axes.set_title_color/3 helpers.
• Add Tucan.Grid.set_color/2 helper.

• Support setting :container to width and height.

Fixed

• Do not flip custom encoding options if :orient flag is set.
• Tucan.ruler/4, Tucan.hruler/3 and Tucan.vruler/3 can now be used independently:

Tucan.layers([
  Tucan.hruler(Tucan.new(), 10),
  Tucan.hruler(Tucan.new(), 15, stroke_width: 2),
  Tucan.vruler(Tucan.new(), 1),
  Tucan.vruler(Tucan.new(), 4.3, line_color: "red")
])

{"$schema":"https://vega.github.io/schema/vega-lite/v5.json","layer":[{"data":{"values":[{}]},"encoding":{"y":{"datum":10}},"mark":{"color":"black","strokeWidth":1,"type":"rule"}},{"data":{"values":[{}]},"encoding":{"y":{"datum":15}},"mark":{"color":"black","strokeWidth":2,"type":"rule"}},{"data":{"values":[{}]},"encoding":{"x":{"datum":1}},"mark":{"color":"black","strokeWidth":1,"type":"rule"}},{"data":{"values":[{}]},"encoding":{"x":{"datum":4.3}},"mark":{"color":"red","strokeWidth":1,"type":"rule"}}]}

• Port more themes from vega-themes, check Tucan.Themes for all available themes.

• Add Tucan.layers/2 helper

Tucan.layers([
  Tucan.scatter(:iris, "petal_width", "petal_length", point_color: "red"),
  Tucan.scatter(:iris, "sepal_width", "sepal_length", point_color: "green")
