IChartModel

public interface IChartModel

Base data model for the chart control.

Implementing classes: JCOChartModel, VectorChartModel, DefaultChartModel

IChartModel and DefaultChartModel
Method	Description	Argument	Return value
firstRow	Sets the pointer of the actual row to first row in the model and returns the number of the first row.	()	int
getColor	Returns the color value of the current row.	()	java.lang.String
getExtension	Returns the extension value of the current row. The extension is a text string that is displayed as tooltip when you move the mouse cursor over the chart element. It shows effect on bar and pie charts, but no effect on line charts.	()	java.lang.String
getFieldName	Returns the field name of the actual row and the specified column.	(int col)	java.lang.String
getFieldValue	Returns the field value of the actual row and the specified column.	(int col)	java.lang.String
getGroupId	Returns the group id of the actual row.	()	java.lang.String
getNumColumns	Returns the number of columns in the model.	()	int
getNumRows	Returns the number of rows in the model.	()	int
getRow	Returns the row position of the pointer (actual row).	()	int
getX	Returns the X value of the actual row.	()	java.lang.String
getY	Returns the Y value of the actual row.	()	java.lang.String
nextRow	Sets the pointer to the next row in the model. If the point has reached the end of the model the method returns false.	()	boolean

JCOChartModel (Methods in addition to the IChartModel/DefaultChartModel)
Method	Description	Argument
setDataSrc	Sets a JCO data table into this model.	(com.sap.mw.jco.JCO. Table DataSrc)

VectorChartModel (Methods in addition to the IChartModel/DefaultChartModel)
Method	Description	Argument
addItem	Adds an entry with extension to the model. The extension is a text string that is displayed as tooltip when you move the mouse cursor over the chart element. It shows effect on bar and pie charts, but no effect on line charts. If you use a pie chart to display the data, the X values will be used.	(java.lang.String groupid, java.lang.String x, java.lang.String y, java.lang.String color, java.lang.String extension)
addItem	Adds an entry with an URL and an alternate text to the model. The alternate text is a text string that is displayed as tooltip when you move the mouse cursor over the chart element. URL and alternate text show effect on bar and pie charts, but no effect on line charts. If you use a pie chart to display the data, the X values will be used.	(java.lang.String groupid, java.lang.String x, java.lang.String y, java.lang.String color, java.lang.String url, java.lang.String altText)

Example

Setting up the VectorChartModel

Syntax Syntax

//  create model
  VectorChartModel model = new VectorChartModel();
//  add two items of the same group with color 20 and an extension

  model.addItem("gr1", "A", "7", "20", "Information to block A");

  model.addItem("gr1", "B", "4", "20", "Information to block B");
// add two items of the same group with color 10, an URL and an 
// alternate text

  model.addItem("gr2","10","3","10","http://www.sap.de","Link to SAP");
  model.addItem("gr2","20","1","10","http://www.bmw.de","Link to BMW");

End of the code.

Setting up the JCOChartModel

Syntax Syntax

// create a new JCO table
    JCO.Table table = new JCO.Table("DAX");

// add the info/header to the table. The header is defined by the 
// column name, data type and length (see JCO table API for details).
    table.addInfo("GROUPID", JCO.TYPE_CHAR, 50);
    table.addInfo("X", JCO.TYPE_CHAR, 50);
    table.addInfo("Y", JCO.TYPE_CHAR, 50);
    table.addInfo("Z", JCO.TYPE_CHAR, 50);
    table.addInfo("COLOR", JCO.TYPE_CHAR, 50);
    table.addInfo("EXTENSION", JCO.TYPE_CHAR, 150);
// append a record to the table. setValue sets the value as string. 
// The second parameter is the column. The numbers are according to 
// the sequence of the definition of the header (see above).
    table.appendRow();
    table.setValue("07.2001", 0);
    table.setValue("SAP", 1);
    table.setValue("158", 2);
    table.setValue("20", 3);
    table.setValue("10", 4);
    table.setValue("href=\"http://www.sap-ag.de/\"", 5);

    ..
/   create a JCOChartModel and set the JCO table
    model = new JCOChartModel();
    ((JCOChartModel) model).setDataSrc(table);

End of the code.
