The following should all appear identical but were generated via different
data functions.
Data from columnsData from rowsData from jsonData from csv fileData from tsv file
Data from csv file using custom dsv with comma delimeter
Data from json fileData named inline data row sourceData named inline data column sourceData named inline json sourceData from arrow file
Named datasets
Named data inline sourceNamed data url sourceNamed data but with no data specified
Loaded geo Files
Data from external topojson file. Should show London boroughs in
multiple nominal colours with legend.
Programatically generated geoFiles
Data from inline geo file. Should be two coloured regions with legend.
Data transforms
Flattened data structures from arrays.Folded data structures into key,value pairs.Pivoted key,value pairs back to unfolded fields.
Domain Specification
Data ranging from 95-105 with no domain specified.
As previous but with domain set to [90,100].
As previous but unioned with domain set to [90,100] (should show 90 to
105).
Data imputation
Simple imputation as a transform adding missing values when a=3 and c=1
by inserting b=0
Simple imputation as a transform adding missing values when a=3 and c=1
by inserting b= mean of non-missing b values when c=1.
Simple imputation as a transform adding missing values when a=3 and c=1
by inserting b= mean of previous two b values when c=1.
Simple imputation as a channel adding missing values when a=3 and c=1 by
inserting b=0
Simple imputation as a channel adding missing values when a=3 and c=1 by
inserting b= mean of non-missing b values when c=1.
Simple imputation as a channel adding missing values when a=3 and c=1 by
inserting b= mean of previous two b values when c=1.
Simple imputation as a channel inserting b=100 when a is 4
Simple imputation as a channel inserting b=100 when a is between 4 and
less than 6
Data Sampling
Sample up to 200 points in right hand chart
Data Binning
Histogram based on pre-binned data
Default binning of Guassian distributed random numbers with mean of 10
and stdev of 2.
As previous but anchoring on 0.5
Sequence Generators
Sine curve sequence using default seq nameSine curve sequence using custom seq name
Filtering
Filter using a single filter expression so that only A C or E categories
are selected.
Filter using composed filter expressions so that only A C or E
categories are selected (should appear identical to previous test).
Annotation layer with null data to prevent inheriting parent in layered
spec.
