public DefaultGraph2DModel()

Method Detail

setXAxis

public void setXAxis(float[] x)

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.

setXAxis

public void setXAxis(double[] x)

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.

setXAxis

public void setXAxis(float a,
                     float b,
                     int n)

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

Parameters:

a - start of interval.

b - end of interval.

n - number of values.

addSeries

public void addSeries(float[] newSeries)

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

addSeries

public void addSeries(double[] newSeries)

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

addSeries

public void addSeries(DefaultGraph2DModel.DataSeries newSeries)

Adds a data series.

addSeries

public void addSeries(float[] newXAxis,
                      float[] newSeries)

Adds a data series. Convenience method.

addSeries

public void addSeries(float[] newXAxis,
                      double[] newSeries)

Adds a data series. Convenience method.

changeSeries

public void changeSeries(int i,
                         DefaultGraph2DModel.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 DefaultGraph2DModel.DataSeries getSeries(int i)

setSeriesVisible

public void setSeriesVisible(int i,
                             boolean flag)

Convenience method.
