Display lines on the contour
contour_line_display_type (enum)
Line display type of contour lines
Options: black, white, contour, constant
num_contours (integer)
Number of contour lines to be displayed in legend
The limit is 500 contours.
vector_function (string)
Function to use for vector display
color_type (enum)
Method used to set the display color
Options: constant, contour
export (boolean)
Flag to export data in ASCII format
active_flag (boolean)
Read and process the command or ignore it
legend_display (boolean)
Flag to toggle on or off the visibility of the legend
legend_title (string)
Add a title to the legend
legend_subtitle (string)
Subtitle of legend
num_labels (integer)
Number of labels used in legend
legend_min (real)
Minimum value in legend
legend_max (real)
Maximum value in legend
legend_use_local (boolean)
Flag to indicate to use values for max and min of legend based on data available for specific visualization.
num_decimal_places (integer)
Number of decimal places to display in legend
legend_orientation (enum)
Specify orientation of the legend
Options: horizontal, vertical
legend_location (enum)
Location of the legend on the image
Options: top_left, top_center, top_right, bottom_left, bottom_center, bottom_right, center_left, center_right
threshold_clipping (boolean)
Specify if the iso surface should be clipped by the specified threshold
threshold_function (string)
Function to be used as threshold
threshold_min (real)
Minimum threshold value
threshold_max (real)
Maximum threshold value
vector_type (enum)
Type of vector displayed
Options: curved or straight
vector_dimension (enum)
Display dimension of the vector
Options: 2d, 3d
vector_scale (real)
Sets the scale of the vector length. Increasing this number will make the vectors larger in size.
vector_thinning_fraction (real)
Percent by which to reduce the number of displayed vectors
From 0 to 1, 1 being the highest
vector_projection (enum)
Vector display projection
Options: total, yz, xz, xy or projected
vector_head_scale (real)
Variable to adjust the size of the vector head
vector_time_limit (real)
When vector_type = curved is selected, this time limit adjusts the length of the tail of the vector.
invert_color_map (boolean)
Option to invert the colors of the colormap
filled_contours (boolean)
Option to display surface with constant colors within a polygon of the surface. If the scalar values change within a polygon, the polygon will then be split and colored appropriately for that polygon.
colormap_name (enum)
Colormap name to use for displaying the scalar function values
Options: spectrum, nasa-1, nasa-2, gray scale, color striped, black & white, striped, zebra, achromatic vision 1, achromatic vision 2, banded blue to red dark, banded blue to red light, banded grayscale, big difference, bio spectrum 1, bio spectrum 2, bloodflow doppler, blue chrome, camouflage, ccm blue red, ccm cool warm, ccm high contrast, ccm spectrum, cd spectrum, cd striped, chrome, cold, dark radiation, dark spectrum, dark green gradient, flame transition, gold, high contrast, hot, hot to cold diff, indigo flame, leaf color, radiation colors, red to blue diff, red to purple diff, relief map, relief map land, relief map ocean, simple flux, small difference, spectrum diff gray, spectrum diff white, steel blue, teal black gradient
log_scale (boolean)
When selected, the scalar will be colored using a logarithmic scale instead of a standard scale.
Can be used on all colormaps.
