Description
cylinder_plot_unif allows you to visualize two dimensional node data that can be thought of as a table having some number of columns and rows. Each column in the table is represented with a cylinder glyph. A cylinder is divided in either vertical or angular direction into a number of segments equal to the number of rows in the column. Each segment is scaled (in either vertical or angular direction) proportionally to the data value of the row. The height or radius of each cylinder can optionally be scaled by the total value of the column (sum of all rows). The sides of the cylinder can optionally be colored by the total column value.The resultant image looks like a 3D pie chart.
Input Ports
in_field
The input must contain a 2-dimensional uniform mesh (Mesh_Unif+Dim2) plus Node_Data.
in_locations
This port is optional. It is a grid describing the location of the cylinders. If nothing is connected to this port, the module will use coordinates of in_field to position the cylinders. This port is useful, for example, to position a cylindrical glyph at certain locations on a map.
ui_parent
A port to connect to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. This default connection is not drawn.
Parameters
Data Component
UIradioBoxLabel. Radio buttons to pick which input Node_Data component to use to create cylinders. The default is the first (0th) component.
vertical segmentation
UItoggle. Indicates whether to use angular of vertical segmentation for each cylinder. The default is off (angular segmentation).
scale height by total
UItoggle. Indicates whether a height for each cylinder (representing a column of an input table data) is scaled by the total value of the column (sum of all rows).
scale radius by total
UItoggle. Indicates whether a radius for each cylinder (representing a column of an input table data) is scaled by the total value of the column (sum of all rows).
color sides by total
UItoggle. Indicates whether the sides of each cylinder (representing a column of an input table data) are colored by the total value of the column (sum of all rows).
radius
UIfield. Represents a default radius value for all cylinders. If "scale radius by total" is set to on, this value is used as the scale for radii of the cylinders.
height
UIfield. Represents a scale value for heights for the cylinders. If "scale height by total" is set to off, this value is used as the height for all the cylinders.
nsegments
UIslider. An integer value that represents the total number of sub-divisions for each cylinder. This number is used to control the graphical accuracy of the cylinders shape -- the higher the value, the more accurate the cylinder is drawn (with a corresponding increase in drawing time). If this value is set to 4 you will get rectangular (4-sided) blocks instead of a cylinder. The default is 36.
start angle
UIslider. Controls the start angle for the first segment in a case when vertical segmentation is off (angular segmentation is specified). Changing this angle is equivalent to rotating all cylinders around their vertical axis. The default is 0.
Default side color (red, green, blue)
UIsliders. Float sliders to adjust the color of the cylinder side. These colors are used only when "color sides by total" is off. The defaults are 1.0.
Output Ports
out_fld
The output field contains cylindrical glyphs.
out_obj
This is a renderable version of the output field.
