# LineBreakChart

LineBreakChart[{{date1, p1}, {date2, p2}, ...}]
makes a line break chart with prices at date .

LineBreakChart[{"name", daterange}]
makes a line break chart of closing prices for the financial entity over the date range daterange.

LineBreakChart[{...}, n]
makes a line break chart where n bars in a row cause a reversal.

## Details and OptionsDetails and Options

• LineBreakChart displays as a series of vertical bars where multiple prices may be included in a single bar, in which the price trend is accentuated.
• LineBreakChart[{{..., p1}, {..., p2}, ...}, n] considers previous prices for dates. If the previous prices have been increasing , then draw a new up bar if and a new down bar if ; otherwise, do not draw a new bar. This works similarly for decreasing prices. If there is no sequence of increasing or decreasing prices of length , the rule applies to the two previous prices.
• LineBreakChart[...] is equivalent to LineBreakChart[..., 3] for a three-line break chart.
• 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 LineBreakChart can be given in the following forms:
•  {datei,pi} a pure date and price pair wi[{datei,pi},...] a date price and wrapper formi->mi a date price with metadata
• A bar may represent several date-price pairs, and the corresponding wrappers will apply to the entire bar.
• Data not given in these forms is taken to be missing and typically is excluded when generating the chart.
• Data for LineBreakChart can be given in the following forms:
•  {e1,e2,...},{"name",daterange} data without overall wrapper w[{e1,e2,...}],w[{"name",daterange}] data with overall wrapper
• 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 LineBreakChart, Labeled and Placed allow the following positions:
•  Top,Bottom,Left,Right,Center positions within bar Above, Below, Before, After positions outside bar {{bx,by},{lx,ly}} scaled position in the label at scaled position in the bar
• LineBreakChart has the same options as Graphics with the following additions and changes:
•  AspectRatio 1/GoldenRatio overall ratio of width to height Axes True whether to draw axes ChartBaseStyle Automatic overall style for bars ChartElementFunction Automatic how to generate raw graphics for bars ChartElements Automatic graphics to use in each of the bars 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 ScalingFunctions None how to scale individual coordinates TrendStyle Automatic how to style up and down trends ScalingFunctions None how 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 up and down bars, respectively.
• EventLabels->{..., datei->lbli, ...} specifies a label associated with . The label will be displayed with the bar 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 LineBreakChart are effectively applied in the order TrendStyle, Style and other wrappers, and ChartElementFunction, with later specifications overriding earlier ones.
