Pie Chart
This plug-in draws a pie chart, filled with data out of a Shared Memory Map. You can use delimited strings or arrays for data transfer via Scene-, Global- or Distributed-Shared Memory.
Note: This plug-in is located in: Built Ins -> Geom plug-ins -> VisualDataTools
This page contains the following topics and procedures:
Pie Chart Properties
-
Shared Mem.: Changes between Scene, Global and Distributed Shared Memory. Use Inactive memory to not forward any values via Shared Memory and the data is taken from the Data field.
-
Data: Determines Shared Memory key name. Data is the default input parameter.
-
Transfer Mode: Sets string- or array-based data transfer.
-
Data Delim.: Defines the value separator sign(s).
-
Number Format: Defines if Viz should get the decimal point separator from the System Locale or Custom settings. If Custom is enabled:
-
Decimal Symbol: Defines which symbol is used as decimal point when Custom Number Format is set.
-
-
Data Fit: Enables data normalization.
-
Data Offset: Adds an offset to the incoming data.
-
-
Values Animation:
Sets the animation type to be created when data change is detected.
-
Disable: No animation.
-
Timer: Creates data transition animation (from an old set of data to a new set) within the specified time set in Duration sec.. Also select an Animation Mode.
-
Director: Creates data transition animation with the Stage Director, that controls the Animation Progress parameter from 0.0% (old data) to 100.0% (new data). Also select an Animation Mode.
-
-
Animation Mode:
-
Concurrent: Changes all nodes concurrently.
-
Left to Right: Transitions from left to right.
-
Right to Left: Transitions from right to left.
-
-
Balance Speed: Relates node values to the position of transformed data when set to On and Animation Mode is set to Left to Right or Right to Left.
Example:
-
Balance Speed: If the values of four nodes change from 0,0,0,0 to 1,9,90,900 in Left to Right mode at 50% of the transformation.
-
Balance Speed Off: Only the first two nodes are transformed to new values.
-
Balance Speed On: The first three nodes are already transformed to new values, and the last node also transformed to 44% of the new values, because the data change from 0 (0+0+0+0) to 1000 (1+9+90+900), at 50% of transformation (in this case the values is changed for 500 of 1000), the first three nodes are already finished and the last node is changed to 400.
-
-
Duration sec.: Sets the duration of the animation in seconds for Timer mode.
-
Diameter: Sets size of pie chart.
-
Total Segmentdeg: Sets the pie chart’s maximum angle in degrees (default: 100% equals 360 degrees).
-
Inner Cutoff: Cuts off a round piece from the cake’s center.
-
Height: Adjusts height.
-
Corners: Defines the minimum amount of corners at the pie’s edge. In dependency on the number of pieces an algorithm adds corners to always give the pie chart the same appearance.
-
Keep Proportions: If enabled, the pie chart would look real. Otherwise each piece’s radius is recalculated.
-
Const. Offset: Sets a constant gap width.
-
Center Offset: Determines each pieces’ distance from the pie’s center.
-
Piece Scaling:
-
All: All pieces equal 100%.
-
Single: Every piece’s size is described by its own 100%(e.g. three pieces mean 300%).
-
Fit: All pieces equal 100%, but they are scaled relatively to fit their new area with the correct values.
-
-
Piece Size%: Parameter for the previous option.
-
Bevel: Activates Bevel mode.
-
Bevel Top: Chamfers cake’s top.
-
Bevel Bottom: Chamfers pie’s bottom.
-
Bevel Size%: Adjusts bevel’s size from 0 to 100.
-
Bevel Steps: Sets roundness via the number of segmentation steps.
-
-
Move Piece: Defines the piece for the next parameter operation. Starts with 0, -1 means nothing selected.
-
Center Offset: Offsets center for a certain piece.
-
Height Offset: Offsets height for a certain piece.
-
Effect Range: Sets the range of pieces to move.
-
Effect Distribution: Sets the distribution of the effect range.
-
-
Pos. Container: Translates every child container to a piece of cake.
-
Container Offset: Adds a certain center offset to each container.
-
Center Container: Centers each translated container.
-
PosX, Y, Z: Activates container translation on the particular axis.
-
Container Pos. Z%: Sets the relative position on the z axis for each child container.
-
-
Map:
-
Color Bar: Sets a single color (V texture coordinate) for a certain piece(e.g. three pieces: V = 0.0, V = 0.5 and V = 1.0).
-
Vertex: Uses vertex colors for each piece starting with ID 0. Color ID moves between the available vertex colors. Color lets you choose color for the current ID.
Note: A chamfer is a beveled edge connecting two surfaces.
-
