Class ScrolledPlot

java.lang.Object
  plot.ScrolledPlot

public class ScrolledPlot
extends java.lang.Object

This class defines the scrolled plot structure used by the PlotPanel to display the plot data using a scrolled image in a plot area with straight plot lines for each plot item (data line), and the lines vary by color or brightness based on each point value.

Constructor Summary

ScrolledPlot(java.lang.String title, java.lang.String x_axis_title, java.lang.String y_axis_title, int num_x_values_max, double x_values_min, double x_values_incr)
Create a ScrolledPlot instance, setting titles and assuming a linear horizontal axis.

Method Summary

static java.awt.Color	getColorForValue(double value, double min_val, double max_val, boolean colors_selected) Generate a color to use given the current value.
Plot	getColumnLinesPlot() Get a plot of the column lines.
Plot	getRowLinesPlot() Get a plot of the row lines, each entry in a column for that row becomes a point in that row line.
void	setValuesRange(double mag_min, double mag_max) Set display magnitude range to map into the rainbow colors.
void	setVerticals(java.util.ArrayList<java.lang.Double> y_values) Set the vertical values for the lines to include.
void	setVerticals(double[] y_values) Set the vertical values for the lines to include.
void	storePlotValues(java.lang.String key_string, double x_value, java.lang.Double[] magnitudes) Store another time instance set of plot points (a single vertical line).

Constructor Detail

ScrolledPlot

public ScrolledPlot(java.lang.String title,
                    java.lang.String x_axis_title,
                    java.lang.String y_axis_title,
                    int num_x_values_max,
                    double x_values_min,
                    double x_values_incr)

Create a ScrolledPlot instance, setting titles and assuming a linear horizontal axis.

Parameters:

title - the plot title

x_axis_title - the horizontal axis title.

y_axis_title - the vertical axis title.

num_x_values_max - the number of horizontal values to include, dropping extra ones off the left side as the plot scrolls.

x_values_incr - the amount to increment the horizontal "tics" for each new sample column.

Method Detail

setVerticals

public void setVerticals(double[] y_values)

Set the vertical values for the lines to include. This gets the min and scale factor for later rescaling of the input values as needed for various plot sizes.

Parameters:

y_values - the values for each of the vertical locations.

setVerticals

public void setVerticals(java.util.ArrayList<java.lang.Double> y_values)

Set the vertical values for the lines to include. This gets the min and scale factor for later rescaling of the input values as needed for various plot sizes.

Parameters:

y_values - the values for each of the vertical locations.

setValuesRange

public void setValuesRange(double mag_min,
                           double mag_max)

Set display magnitude range to map into the rainbow colors.

Parameters:

mag_min - the minimum value expected.

mag_max - the maximum value expected.

storePlotValues

public void storePlotValues(java.lang.String key_string,
                            double x_value,
                            java.lang.Double[] magnitudes)

Store another time instance set of plot points (a single vertical line).

Parameters:

key_string - the key string for the line.

x_value - the time value for the samples.

magnitudes - the array of magnitudes, one each for the vertical values reserved.

getColumnLinesPlot

public Plot getColumnLinesPlot()

Get a plot of the column lines.

getRowLinesPlot

public Plot getRowLinesPlot()

Get a plot of the row lines, each entry in a column for that row becomes a point in that row line.

getColorForValue

public static java.awt.Color getColorForValue(double value,
                                              double min_val,
                                              double max_val,
                                              boolean colors_selected)

Generate a color to use given the current value.

Parameters:

value - the value to convert to a color.

Returns:

the color for that value.
