LineBreakChart

LineBreakChart
makes a line break chart with prices at date .
LineBreakChart
makes a line break chart of closing prices for the financial entity over the date range daterange.
LineBreakChart
makes a line break chart where n bars in a row cause a reversal.
  • 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 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.
  • The dates are considered an ordered sequence of events, and are not shown on an absolute time scale.
  • 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->mia 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.
{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
Top,Bottom,Left,Right,Centerpositions within bar
Above, Below, Before, Afterpositions outside bar
{{bx,by},{lx,ly}}scaled position in the label at scaled position in the bar
AspectRatio1/GoldenRatiooverall ratio of width to height
AxesTruewhether to draw axes
ChartBaseStyleAutomaticoverall style for bars
ChartElementFunctionAutomatichow to generate raw graphics for bars
ChartElementsAutomaticgraphics to use in each of the bars
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
ScalingFunctionsNonehow to scale individual coordinates
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 .
  • With the setting ChartElements, up and down will be used for up and down bars, respectively.
  • EventLabels specifies a label associated with . The label will be displayed with the bar that has a date range that includes .

Wrappers can be nested:
Override the default tooltips:
Use PopupWindow to provide additional drilldown information:
Button can be used to trigger any action:
Specify styles for up and down trends:
Use preset styles:
ChartBaseStyle can be used to set a style for all chart elements:
Style can be used to override styles:
Use built-in programmatically generated bars:
Use Labeled to add a label to a bar:
Use symbolic positions for label placement:
Label a list of date events:
Use Placed to control the positioning of labels, using the same positions as for Labeled:
Use the default axes:
Turn off the axes:
Axes origin is on the left by default:
Place the axis at the end of February:
Use named positions for the axis:
Use ChartBaseStyle to style bars:
ChartBaseStyle combines with TrendStyle:
ChartStyle may override settings for ChartBaseStyle:
Style may override settings for ChartBaseStyle:
Use any Graphics object for the bars:
Use different markers for up and down trends:
Graphical elements pick up the style from TrendStyle:
Use images for the bars:
Shapes are stretched to fill the bar by default:
Use a fixed height for the elements:
Use explicit sizes for width and height:

For detailed settings, use PalettesChartElementSchemes:
These ChartElementFunction show the global scale:
Write a custom ChartElementFunction:
Events are labeled at the price by default:
Use Placed to control label placement
Use Placed to control label appearance:
Grid lines are used by default.
Turn off date grid lines:
Turn off price grid lines:
Place grid lines at month or year boundaries:
Use dotted grid lines for months and red grid lines for years:
By default, GridLinesStyle uses dotted grid lines with emphasized year grid lines:
Year grid lines are emphasized:
Style grid lines:
Generate a paired bar chart with interactive highlighting:
Emphasize performance by disabling interactive behaviors:
Typically, less memory is required for noninteractive charts:
LineBreakChart automatically draws all price dates:
Limit to a specific date range:
PlotRange only includes dates for which there is data:
Prices are normally shown on a linear scale:
Show prices on a logarithmic scale:
TrendStyle uses green for up trends and red for down trends by default:
Use black for up trends and red for down trends:
Use named styles:
TrendStyle combines with ChartBaseStyle:
With TrendStyle set to None, the base style is used for up trends and empty bars for down trends:
TrendStyle->style uses style for up trends and empty bars for down trends:
Visualize the mean temperature in Chicago using WeatherData as a LineBreakChart:
Reversals occur when the price change exceeds the previous n bars:
LineBreakChart only shows time periods with significant change in price:
Use InteractiveTradingChart to visualize and interactively analyze financial data:
