Class Figure

java.lang.Object
org.gcube.common.health.api.Figure
public final class Figure extends Object
One figure of a group of Statistics, with the label a page shows and its kind, which tells the page how to draw it:
  • "number": one number, drawn as a tile;
  • "distribution": the parts of a whole by name (e.g. the requests by outcome), drawn as a donut with percentages;
  • "states": the parts of a whole by state (e.g. the Contexts by state), with what each state means (State), drawn like a distribution with the colour of each meaning;
  • "values": a number by name that is not a part of a whole (e.g. an average per depth), drawn as bars, without percentages.

    • number

      public static Figure number(String id, String label, Number value)
      Creates a figure that is a number.
      Parameters:
      id - the identifier of the figure in its group, lowerCamelCase
      label - what a page writes next to it, e.g. "Requests since start"
      value - the number
      Returns:
      the figure

    • distribution

      public static Figure distribution(String id, String label, Map<String,? extends Number> parts)
      Creates a figure that gives the parts of a whole by name, in the order given.
      Parameters:
      id - the identifier of the figure in its group, lowerCamelCase
      label - what a page writes next to it, e.g. "Requests by outcome"
      parts - the number of each part, by its name
      Returns:
      the figure

    • states

      public static Figure states(String id, String label, Map<String,? extends Number> parts, Map<String,State> meaning)
      Creates a figure that gives the parts of a whole by state, in the order given, with what each state means.
      Parameters:
      id - the identifier of the figure in its group, lowerCamelCase
      label - what a page writes next to it, e.g. "Contexts by state"
      parts - the number of each state, by its name (e.g. active, suspended)
      meaning - what each state means; every state of parts must have one
      Returns:
      the figure
      Throws:
      IllegalArgumentException - when a state has no meaning

    • values

      public static Figure values(String id, String label, Map<String,? extends Number> values)
      Creates a figure that gives a number by name that is not a part of a whole (e.g. an average, a median or a maximum per depth), in the order given.
      Parameters:
      id - the identifier of the figure in its group, lowerCamelCase
      label - what a page writes next to it, e.g. "Children per Context, average by depth"
      values - the number, by its name
      Returns:
      the figure
