DefaultCategoryGraph2DModel

public DefaultCategoryGraph2DModel()

Method Detail

setCategories

public void setCategories(java.lang.Object[] cat)

Sets the default x-axis values. A copy of the values is made. This method does not change the x-axis values of any data series and so does not fire any events.

addSeries

public void addSeries(float[] newSeries)

Adds a data series using the default values for the x-axis. Be sure to call setCategories first.

addSeries

public void addSeries(double[] newSeries)

Adds a data series using the default values for the x-axis. Be sure to call setCategories first.

addSeries

public void addSeries(DefaultCategoryGraph2DModel.DataSeries newSeries)

Adds a data series.

addSeries

public void addSeries(java.lang.Object[] newXAxis,
                      float[] newSeries)

Adds a data series. Convenience method.

addSeries

public void addSeries(java.lang.Object[] newXAxis,
                      double[] newSeries)

Adds a data series. Convenience method.

changeSeries

public void changeSeries(int i,
                         DefaultCategoryGraph2DModel.DataSeries newSeries)

Changes a data series.

changeSeries

public void changeSeries(int i,
                         float[] newSeries)

Changes a data series. Convenience method.

changeSeries

public void changeSeries(int i,
                         double[] newSeries)

Changes a data series. Convenience method.

removeSeries

public void removeSeries(int i)

Remove a data series.

getSeries

public DefaultCategoryGraph2DModel.DataSeries getSeries(int i)

setSeriesVisible

public void setSeriesVisible(int i,
                             boolean flag)

Convenience method.

tableChanged

public void tableChanged(javax.swing.event.TableModelEvent evt)

Implementation of TabelModelListener. Application code will not use this method explicitly, it is used internally.

Specified by:

tableChanged in interface javax.swing.event.TableModelListener

getCategory

public java.lang.String getCategory(int i)

Description copied from interface: CategoryGraph2DModel

Returns the ith category.

Specified by:

getCategory in interface CategoryGraph2DModel

getValue

public float getValue(int i)

Description copied from interface: CategoryGraph2DModel

Returns the value for the ith category.

Specified by:

getValue in interface CategoryGraph2DModel

seriesLength

public int seriesLength()

Description copied from interface: CategoryGraph2DModel

Returns the number of data points in the current series.

Specified by:

seriesLength in interface CategoryGraph2DModel

firstSeries

public void firstSeries()

Description copied from interface: CategoryGraph2DModel

Selects the first data series.

Specified by:

firstSeries in interface CategoryGraph2DModel

nextSeries

public boolean nextSeries()

Description copied from interface: CategoryGraph2DModel

Selects the next data series. Returns false if there is no next series.

Specified by:

nextSeries in interface CategoryGraph2DModel
