Instance Method Details

#data ⇒ Object

Base Mixin Set the data callback or retrieve the chart’s data set. The data callback is passed the chart’s group and by default will return group.all(). This behavior may be modified to, for instance, return only the top 5 groups:

# File 'lib/sol/base_chart.rb', line 58

def data
end

#dimension(val = nil) ⇒ Object

Base Mixin Set or get the dimension attribute of a chart. In dc a dimension can be any valid crossfilter dimension. If a value is given, then it will be used as the new dimension. If no value is specified then the current dimension will be returned.

# File 'lib/sol/base_chart.rb', line 69

def dimension(val = nil)
  return @properties["dimension"] if !val
  @properties["dimension"] = val
  return self
end

#group(method, name = nil) ⇒ Object

Base Mixin Set or get the group attribute of a chart. In dc a group is a crossfilter group. Usually the group should be created from the particular dimension associated with the same chart. If a value is given, then it will be used as the new group.

If no value specified then the current group will be returned. If name is specified then it will be used to generate legend label.

def group(method, name = nil)
  
  @group_name = @name.downcase + "Group"
  @group = 
    "var #{@group_name} = #{@dim}.group().#{Sol.camelcase(method.to_s)}(function(d) {return d[\"#{@y_column}\"];});"
  @properties["group"] = @group_name
  return self

end

#grouped? ⇒ Boolean

Returns:

  • (Boolean)

def grouped?
  @group != nil
end

#height(val = nil) ⇒ Object

Base Mixin Set or get the height attribute of a chart. The height is applied to the SVG element generated by the chart when rendered (or rerendered). If a value is given, then it will be used to calculate the new height and the chart returned for method chaining. The value can either be a numeric, a function, or falsy. If no value is specified then the value of the current height attribute will be returned.

By default, without an explicit height being given, the chart will select the width of its anchor element. If that isn’t possible it defaults to 200. Setting the value falsy will return the chart to the default behavior
