Class StockChartFactory

java.lang.Object
  com.davisor.graphics.chart.ChartFactory
      com.davisor.graphics.chart.AxisFactory
          com.davisor.graphics.chart.BarFactory
              com.davisor.graphics.chart.ColumnBarFactory
                  com.davisor.graphics.chart.StockChartFactory

All Implemented Interfaces:: com.davisor.core.Dupable, com.davisor.core.MIMETypes, com.davisor.core.Public

Direct Known Subclasses:: CandlestickFactory, OHLCFactory

public abstract class StockChartFactory
extends ColumnBarFactory

StockChartFactory is an abstract class for stock charts based on bar chart producer.

Data

StockChartFactory consumes Open-High-Low-Close data. That data must be given inside a group in that order. "Open" and "Close" values may be optional depending on the chart type. See sub class documentation for details.

 Example: 

 <data>
  <group type="value">
   <column values="25 27 60 51" />
   <column values="30 70 70 80" />
   <column values="20 20 40 40" />
   <column values="26 55 55 75" /> 
  </group>
  <column type="label" values="Mon Tue Wed Thu" />
 </data>

There can be more than one group, but then the number of columns inside groups must be the same. I.e. if "open"-data exists in one group, it must be available in all groups.

Rendering Attributes

This factory inherits lots of it's attribute and data operation logic from AxisFactory and BarFactory superclasses. However, there are some differences. The following attributes can be used:

pointColor - defines outline color (*)
pointPaint - defines interior paint when available (*)
pointStroke - defines outline stroke
annotation attributes - defines annotation associated to drawn shapes

(*) Color and paint can alter depending on the values of "Open" and "Close". If pointColor or pointPaint is a palette, then the first palette color is used in cases when "Close"-value is greater or equal than "Open"-value. The second palette color is used when "Close"-value is smaller than "Open"-value. Default color is black and default paint is "white,black".

Warning!

All the common rendering possibilities of Davisor Chart make no sense with these very specialized chart types. Because the usage of nonsense attributes is not actively blocked, it is possible to get odd results with some attribute combinations. Try to avoid using non-supported features. Those include especially:

Isometric (3D) drawing
Cumulative and hidden values
Drawing values onto chart
Zero stroke

Constructor Summary
`StockChartFactory()` Default constructor.
`StockChartFactory(BarFactory factory)` Copy constructor.

Method Summary
`protected void`	`drawOHLCBar(java.awt.Graphics2D g, java.awt.Paint color, java.awt.Paint paint, int group, int bar, float zero, float groupSize, float barSize, float gapSize, float borderWidth, float size, DataValue open, DataValue high, DataValue low, DataValue close, DataValue minValue, DataValue maxValue)` Convert data values to device units and call sub-class implementation.
`protected abstract void`	`drawOHLCBar(java.awt.Graphics2D g, java.awt.Paint color, java.awt.Paint paint, int group, int bar, float zero, float groupSize, float barSize, float gapSize, float borderWidth, float open, float high, float low, float close)` Draw Open-High-Low-Close data onto chart.
`protected void`	`renderChart(AxisFactory.AxisContext context, AxisFactory.AxisMetrics metrics, ChartAxes axes, Chart chart)` Renders a stock chart based on Open-High-Low-Close data.
`protected DataValue[]`	`resolveDataLimits(ChartData data, ChartAttributes attr, PlotRenderAttributes plot, int[] channels, boolean isometric, boolean[] cumulative)` Resolves data limits without taking care of cumulativity since stock prices are not cumulative in their nature.
