Constructor Detail

FunctionGraph

protected FunctionGraph()

Display a 2d graph showing y(x), with labelled scales. This constructor is for subclasses only, which may need to perform some operations before calling initialise().

FunctionGraph

public FunctionGraph(double x0,
             double xStep,
             double[] y)

Display a 2d graph showing y(x), with labelled scales.

Parameters:

x0 - x0

xStep - xStep

y - y

FunctionGraph

public FunctionGraph(int width,
             int height,
             double x0,
             double xStep,
             double[] y)

Display a 2d graph showing y(x), with labelled scales.

Parameters:

width - width

height - height

x0 - x0

xStep - xStep

y - y

Method Detail

initialise

public void initialise(int width,
              int height,
              double newX0,
              double newXStep,
              double[] data)

updateData

public void updateData(double newX0,
              double newXStep,
              double[] data)

Replace the previous data with the given new data. Any secondary data series added using { addDataSeries(double[], Color, int, int) are removed.

Parameters:

newX0 - x position of first data point

newXStep - distance between data points on X axis

data - all data points

setPrimaryDataSeriesStyle

public void setPrimaryDataSeriesStyle(Color newGraphColor,
                             int newGraphStyle,
                             int newDotStyle)

setYMinMax

public void setYMinMax(double theYMin,
              double theYMax)

Manually set the min and max values for the y axis.

Parameters:

theYMin - the Y min

theYMax - the Y max

addDataSeries

public void addDataSeries(double[] data,
                 Color newGraphColor,
                 int newGraphStyle,
                 int newDotStyle)

Add a secondary data series to this graph.

Parameters:

data - the function data, which must be of same length as the original data. updateData(double, double, double[])

newGraphColor - a colour

newGraphStyle - the style for painting this data series. One of DRAW_LINE, DRAW_DOTS, 3, DRAW_HISTOGRAM.

newDotStyle - the shape of any dots to use (meaningful only with newGraphStyle == DRAW_DOTS or DRAW_LINEWITHDOTS). One of DOT_EMPTYCIRCLE, DOT_EMPTYDIAMOND, DOT_EMPTYSQUARE, DOT_FULLCIRCLE, DOT_FULLDIAMOND, DOT_FULLSQUARE. For other graph styles, this is ignored, and it is recommended to set it to -1 for clarity.

getZoomX

public double getZoomX()

setZoomX

public void setZoomX(double factor)

Set the zoom of the X

Parameters:

factor - the zoom factor for X; 1 means that each data point corresponds to one pixel; 0.5 means that 2 data points are mapped onto one pixel; etc.

createGraphImage

protected void createGraphImage()
