Method Detail

getScale7div

float getScale7div()

Returns the scaling per division. One division is 1/10 of full y presentation, like usual on oscilloscopes.

getOffset

float getOffset()

Returns the value which is shown at the 0-line.

getLinePercent

int getLinePercent()

Returns the position of the 0-line as value from 0 to 100 for this track.

getLineColor

GralColor getLineColor()

Returns the set color for this line.

getDataPath

java.lang.String getDataPath()

Description copied from interface: GralSetValue_ifc

Changes the data path

Specified by:

getDataPath in interface GralSetValue_ifc

Returns:

the last one.

setTrackScale

void setTrackScale(float scale7div,
                   float offset,
                   int line0)

Change the scaling of a track.

Parameters:

trackNr - Number of the track in order of creation, 0 ist the first.

scale7div - value per division

offset - value, which is shown at line0

line0 - percent of 0-line in graphic.

groupTrackScale

void groupTrackScale(GralCurveViewTrack_ifc from)

Refers the same instance GralCurveView.TrackScale with the other track. All setTrackScale(float, float, int) with tracks which are shared influences one another.

Parameters:

from - one of the track of a scale group.

isGroupedTrackScale

boolean isGroupedTrackScale(GralCurveViewTrack_ifc with)

Checks whether the scaling is shared with the other given thread

Parameters:

with - The other track.

Returns:

true if it refers the same instance of scaling values.

ungroupTrackScale

void ungroupTrackScale()

Creates an own instance for the scaling values.

setLineProperties

void setLineProperties(GralColor color,
                       int width,
                       int pattern)

Sets the properties for this track.

Parameters:

color - The color of line, null: no change

width - The thickness of the line. 0: no change

pattern - a Pattern of the line. Yet the pattern is not used (TODO). Value 0 doesn't change the current one.

setVisible

void setVisible(int mode)

Set the state to show. 0=hidden, don't show, but the values are stored. 1= show normal. 2= show lifted out (selected).

getVisible

int getVisible()

Returns the state to show. 0=hidden, don't show, but the values are stored. 1= show normal. 2= show lifted out (selected).

setDataPath

void setDataPath(java.lang.String path)

Description copied from interface: GralSetValue_ifc

Sets the data path. It is a String in application context.

Specified by:

setDataPath in interface GralSetValue_ifc

getValueCursorLeft

float getValueCursorLeft()

getValueCursorRight

float getValueCursorRight()

getValueLast

float getValueLast()

getValueMin

float getValueMin()

getValueMax

float getValueMax()
