Constructor Detail

GraphView

public GraphView()

Creates a new instance of GraphPanel. Set up our data structures (= simple arrays) and define some constants.

Method Detail

setAxisPanel

public void setAxisPanel(javax.swing.JPanel ax)

Specify the panel displaying the Y-axis.

Parameters:

ax - the panel to be used to display the y-axis

is2G

public boolean is2G()

Returns whether the accelerometer data using the 2G or 6G scales.

Returns:

true if using the 2G scale, false if using the 6G scale

getMaxWidth

public int getMaxWidth()

Return the width that the current telemetry data occupies. Used by printing to determine number of pages needed.

Returns:

the width (in pixels) that the current telemetry data occupies

writeData

public boolean writeData(java.io.File file)

Write the current acceleration telemetry data out to a file.

Parameters:

file - the file to write the data into

Returns:

true if successful, false otherwise

readTelemetryFile

public boolean readTelemetryFile(java.io.File file)

Read in acceleration telemetry data from a file.

Parameters:

file - the file to read the data from

Returns:

true if successful, false otherwise

takeData

public void takeData(java.lang.String id,
                     long tMS,
