PointFigureChart
PointFigureChart[{{date1,p1},{date2,p2},…}]
makes a point and figure chart with prices pi at date datei.
PointFigureChart[{"name",daterange}]
makes a point and figure chart of closing prices for the financial entity "name" 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 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 datei are considered an ordered sequence of events and are not shown on an absolute time scale.
- The date formats for datei are the same as used in DateListPlot.
- The "name" 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 {datei,Quantity[pi,ui]} a date-price pair with a unit wi[{datei,pi},…] a date-price pair and wrapper wi formi->mi a date-price pair with metadata mi - 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 TimeSeries[…],EventSeries[…],TemporalData[…] time series, event series, and temporal data 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,Center positions within point or figure Above, Below, Before, After positions outside point or figure {{bx,by},{lx,ly}} scaled position {lx,ly} in the label at scaled position {bx,by} in the point or figure - PointFigureChart has the same options as Graphics with the following additions and changes:
-
AspectRatio Automatic overall ratio of height to width Axes True whether to draw axes ChartBaseStyle Automatic overall style for bars ChartElementFunction Automatic how to generate raw graphics for point and figure bars ChartElements Automatic graphics to use in each of the points and figures DateFunction Automatic how to convert dates to standard form EventLabels None events to label GridLines Automatic grid lines to draw GridLinesStyle Automatic style for grid lines PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotTheme $PlotTheme overall theme for the chart TrendStyle Automatic how to style up and down trends ScalingFunctions None how to scale the axis
TargetUnits Automatic units to display in the chart - The arguments supplied to ChartElementFunction are the bar region {{xmin,xmax},{ymin,ymax}}, the date-price pairs list, and metadata {m1,m2,…}.
- A list of built-in settings for ChartElementFunction can be obtained from ChartElementData["PointFigureChart"].
- 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 datei. The label will be displayed with the point or figure that has a date range that includes datei.
- With ScalingFunctions->sy, the function sy 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.
