PointFigureChart

PointFigureChart[{{date1, p1}, {date2, p2}, ...}]
makes a point and figure chart with prices at date .

PointFigureChart[{"name", daterange}]
makes a point and figure chart of closing prices for the financial entity over the date range daterange.

PointFigureChart[{...}, s, n]
makes a point and figure chart with point and figure height s and n reversals.

Details and OptionsDetails and Options

  • A point and figure chart is drawn as a series of bars with alternating directions. Changes that continue a trend are drawn in increments of a fixed size. A new column is drawn when the direction changes by n units.
  • PointFigureChart[...] is equivalent to PointFigureChart[..., {"Relative", 0.03}, 3] for 3% of the price range and three reversals.
  • The following arguments can be used to specify the step s:
  • {"Relative",p}fraction of price range (default)
    {"Absolute",p}absolute price change
  • The dates are considered an ordered sequence of events and are not shown on an absolute time scale.
  • The date formats for are the same as used in DateListPlot.
  • The and daterange are the same as used in FinancialData.
  • Data elements for PointFigureChart can be given in the following forms:
  • {datei,pi}a pure date-price pair
    wi[{datei,pi},...]a date-price pair and wrapper
    formi->mia date-price pair with metadata
  • A point and figure chart element may represent several date-price pairs, and the corresponding wrappers will apply to the entire chart element.
  • Data not given in these is taken to be missing and typically is excluded when generating the chart.
  • Data for PointFigureChart can be given in the following forms:
  • {e1,e2,...}list of elements with or without wrappers
    w[{e1,e2,...}]wrapper applied to the whole data
  • The following wrappers can be used for data elements:
  • Annotation[e,label]provide an annotation
    Button[e,action]define an action to execute when the element is clicked
    EventHandler[e,...]define a general event handler for the element
    Hyperlink[e,uri]make the element act as a hyperlink
    Labeled[e,...]display the element with labeling
    PopupWindow[e,cont]attach a popup window to the element
    StatusArea[e,label]display in the status area when the element is moused over
    Style[e,opts]show the element using the specified styles
    Tooltip[e,label]attach an arbitrary tooltip to the element
  • In PointFigureChart, Labeled and Placed allow the following positions:
  • Top,Bottom,Left,Right,Centerpositions within point or figure
    Above, Below, Before, Afterpositions outside point or figure
    {{bx,by},{lx,ly}}scaled position in the label at scaled position in the point or figure
  • PointFigureChart has the same options as Graphics with the following additions and changes:
  • AspectRatioAutomaticoverall ratio of width to height
    AxesTruewhether to draw axes
    ChartBaseStyleAutomaticoverall style for bars
    ChartElementFunctionAutomatichow to generate raw graphics for point and figure bars
    ChartElementsAutomaticgraphics to use in each of the points and figures
    DateFunctionAutomatichow to convert dates to standard form
    EventLabelsNoneevents to label
    GridLinesAutomaticgrid lines to draw
    GridLinesStyleAutomaticstyle for grid lines
    PerformanceGoal$PerformanceGoalaspects of performance to try to optimize
    TrendStyleAutomatichow to style up and down trends
    ScalingFunctionsNonehow to scale the axis
  • The arguments supplied to ChartElementFunction are the bar region , the date-price pairs list, and metadata .
  • A list of built-in settings for ChartElementFunction can be obtained from .
  • With the setting ChartElements->{up, down}, up and down will be used for figures and points, respectively.
  • EventLabels->{..., datei->lbli, ...} specifies a label associated with . The label will be displayed with the point or figure that has a date range that includes .
  • With ScalingFunctions->sy, the function is applied to the prices. ScalingFunctions only affects the display and none of the controls.
  • Style and other specifications from options and other constructs in PointFigureChart are effectively applied in the order TrendStyle, Style and other wrappers, and ChartElementFunction, with later specifications overriding earlier ones.
