Member Function Documentation

int VectPlot::drawBar	(	Plot &	plot,
		const char *	locate
	)

Draws the color bar legend

Parameters:

	plot	Plot object
	locate	Location of bar

int VectPlot::setBase

(

float

val

)

Sets the contour base value used in color fill and other parameters

Parameters:

val

Base value

int VectPlot::setColorFill

(

const char *

str

)

Sets the color fill parameters

Parameters:

str

Color fill string

int VectPlot::setColorLine

(

const char *

str

)

Sets the color for line contours

Parameters:

str

Color string

References WXP::String::set().

int VectPlot::setColorTable

(

const char *

str

)

Sets the color table parameters

Parameters:

str

Color table string

int VectPlot::setDensity

(

int

val

)

Sets the density of streamlines on a plot. It is the number of streamlines that can exist in a grid box

Parameters:

val

Density value

int VectPlot::setInterval

(

float

val

)

Sets the contour interval

Parameters:

val

Contour interval

int VectPlot::setSkip

(

int

val

)

Sets the skip factor for gridpoints. This sets the interval between gridpoints for vectors and the size of grid boxes for streamline density

Parameters:

val

Skip factor

int VectPlot::setSpeed

(

float

val

)

Sets the wind speed to which vector lengths are fixed

Parameters:

val

Speed value
