CanvasXpress: API - Data Transformation

A declarative dplyr/tidyr data-grammar recipe applied over the tidy substrate BEFORE the chart wrangle. An ordered array of ops: {op:"filter", col, cmp (one of ==,!=,>,>=,<,<=,in), value}; {op:"mutate", col, fn} where fn is a transform name (log2/log10/-log2/-log10/exp2/exp10/sqrt); {op:"arrange", by, desc}; {op:"select", cols:[...]}. Applied left-to-right like the dplyr pipe; mutating the recipe changes the rendered data (generative). Equivalent of dplyr filter/mutate/arrange/select.

Type: array

Default: []

Used in: Area, AreaLine, Bar, BarLine, Boxplot, Bubble, Bullet, Chord, Circular, Contour, Correlation, Density, DotLine, Dotplot, Dumbbell, Fish, Gantt, Heatmap, Histogram, Line, Lollipop, Map, Meter, ParallelCoordinates, Pie, Radar, SPLOM, Sankey, Scatter2D, Scatter3D, ScatterBubble2D, Stacked, StackedLine, StackedPercent, StackedPercentLine, Streamgraph, Sunburst, TagCloud, Tree, Treemap, Violin, Waterfall

Default axis to use to transform the data when either z-score or ratio transformation is used

Type: string

Default: samples

Options: samples, variables

Used in: Area, AreaLine, Bar, BarLine, Boxplot, Bubble, Bullet, Chord, Circular, Contour, Correlation, Density, DotLine, Dotplot, Dumbbell, Fish, Gantt, Heatmap, Histogram, Line, Lollipop, Map, Meter, ParallelCoordinates, Pie, Radar, SPLOM, Sankey, Scatter2D, Scatter3D, ScatterBubble2D, Stacked, StackedLine, StackedPercent, StackedPercentLine, Streamgraph, Sunburst, TagCloud, Tree, Treemap, Violin, Waterfall

Default transformation type for ALL the data. Data can also be transformed by axis (x,y,z) to give more flexibility. false, save, reset and undo are NOT real transformations. They are only used in the canvasXpress UIs to save the transformed data

Type: string

Default:

Options: False, log2, log10, -log2, -log10, exp2, exp10, sqrt, percentile, zscore, ratio2, ratio10, save, reset, undo

Used in: Area, AreaLine, Bar, BarLine, Boxplot, Bubble, Bullet, Chord, Circular, Contour, Correlation, Density, DotLine, Dotplot, Dumbbell, Fish, Gantt, Heatmap, Histogram, Line, Lollipop, Map, Meter, ParallelCoordinates, Pie, Radar, SPLOM, Sankey, Scatter2D, Scatter3D, ScatterBubble2D, Stacked, StackedLine, StackedPercent, StackedPercentLine, Streamgraph, Sunburst, TagCloud, Tree, Treemap, Violin, Waterfall
