Variable Specification
The full variable specification reflects all the options available when specifying your variable. Below are all available variable parameters:
- variable
String: The name a well-adjusted human person might use to describe your variable - numerator
String: The numerator for your variable. If you're only using properties from your geospatial data (eg. GeoJSON properties on each feature), you can call the column name directly here. Otherwise, this should refer to the joined data table you'd like to use. - nProperty
String: The data column of your numerator to use (eg. 'Total Population') - nRange
Number: For time-series data, specify a temporal range for the variable (eg. 1 - daily, 7 - weekly, etc). Cumulative time-series data can be used by calling thisnRangewithnull - nIndex
Number: ... - denominator
String: The denominator for your variable. Same conditions apply asnumerator! - dProperty
String: The data column of your numerator to use (eg. 'Land Area') - dRange
Number: SeenRange. If not declared - dIndex
Number: ... - scale
Number: The scale calculated values will be mutiplied by. For example, if you're using a percentage variable that is normalized from 0-1, you might set a scale of100. For many public health metrics, a scale of values per 10,000 or 100,000 may be useful. - binning
String: The binning strategy you want for this variable. By default, natural breaks will be used. Read more on available binning strategies - numberOfBins
Number: The number of bins to be generated. Defaults to 5. Built-in color brewer schemes support 3-9 bins. - colorScale
ObjectorArray: A built-in color scale of your choice (eg.colors.colorBrewer.Reds) or a custom array of RGB values (eg.[[0,20,40],[20,40,80],[40,80,120]]). If using a custom scale, you should include the same number of colors as the number of bins. - fixedScale
Array: Pre-define a range of bins by specifying the breakpoints as an array (eg.[5,10,15]will produce bins Less than 5, 5 to 10, 10 to 15, Greater than 15)
