Detailed Description

Rendering node that displays a legend.

Displays a legend representing the current colormap. A colormap is specified using the MoColorMapping derived nodes. However, the legend does not take into account the MoCombineColorMapping node.

The legend is drawn in a rectangle defined by the bottomLeft and topRight 2D points given in Normalized Device Coordinates [0..1].

Member Data Documentation

SoSFVec2f MoLegend::bottomLeft

Bottom left corner of the rectangle in which the legend will be drawn.

In NDC units [0..1]. Default is (0,0).

SoSFBool MoLegend::displayValues

If TRUE, display numValues values starting from the minimal to the maximal values of the colormap.

Default FALSE.

SoSFDouble MoLegend::maxValue

The maximum value defining the range of data to display in the legend.

Default 0.

Note:: If not set, the min and max values are retrieved from the colormap.

SoSFDouble MoLegend::minValue

The minimum value defining the range of data to display in the legend.

Default 0.

Note:: If not set, the min and max values are retrieved from the colormap.

SoSFInt32 MoLegend::numValues

The number of values displayed near the colorbar.

This field is ignored if displayValues is FALSE. Default 2.

SoSFString MoLegend::title

The title of the legend.

SoSFColor MoLegend::titleColor

Color for the title of the legend.

SoSFFloat MoLegend::titleFontSize

The size of the font for the title of the legend.

Default 10 pixels.

SoSFEnum MoLegend::titlePosition

The position of the title relative to the legend box.

Use enum Position. Default is POS_BOTTOM.

SoSFVec2f MoLegend::topRight

Top-right corner of the rectangle in which the legend will be drawn.

In NDC units [0..1]. Default is (0,1).

SoSFEnum MoLegend::valueNotation

Defines the notation type (fixed or scientific) used to display the values of this legend.

Use enum Notation. Default is DEFAULT_NOTATION.

Note: The field valuePrecision is interpreted according to valueNotation.

NOTE: field available since Open Inventor 9.6

SoSFUInt32 MoLegend::valuePrecision

Defines the maximum number of significant digits to display, or the maximum number of digits after the decimal point depending on the value of the field valueNotation.

Default value is 0.

When using NOTATION_DEFAULT the valuePrecision field specifies the maximum number of meaningful digits to display in total counting both those before and those after the decimal point. Notice that it is not a minimum, and therefore it does not pad the displayed number with trailing zeros if the number can be displayed with less digits than the precision.

When using NOTATION_FIXED or NOTATION_SCIENTIFIC, the precision field specifies exactly how many digits to display after the decimal point, even if this includes trailing decimal zeros. The digits before the decimal point are not relevant for the precision in this case.

NOTE: field available since Open Inventor 9.6

SoSFColor MoLegend::valuesColor

Color for the values of the legend.

SoSFFloat MoLegend::valuesFontSize

The size of the font for the values of the legend.

Default 10 pixels.

SoSFBool MoLegend::vertical

If TRUE, the legend is vertical.

Otherwise it is horizontal. Default FALSE (horizontal)
