Scatter Chart

images/download/thumbnails/95402957/ico_scatterc.png
The Scatter Chart plug-in draws a scatter 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.

Supported Pipelines

This page contains the following topics and procedures:

Scatter 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.

  • Key DataX: Determines Shared Memory key name for X values. DataX is the default input parameter for X values.

  • Key DataY: Determines Shared Memory key name for Y values. DataY is the default input parameter for Y values.

  • DataZ Position: Uses DataZ for Z-axis positioning.

  • Key DataZ: Determines Shared Memory key name for Z values. DataZ is the default input parameter for Z values.

  • 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.

  • DataX, -Y, -Z Fit: Enables data normalization.

  • DataX, -Y, -Z Scale: Scales input by the selected factor.

  • DataX, -Y, -Z Offset: Adds an offset to the incoming data.

  • DataX, -Y, -Z Auto Scale: Enables automatic data normalization.

  • DataX, -Y, -Z Detect Limits: Detects minimum and maximum of all values and scales them to adjusted Start and Stop.

  • DataX, -Y, -Z Threshold: Adds a definable offset to the detected limit.

  • DataX, -Y, -Z Start: Determines lower Auto Scale edge.

  • DataX, -Y, -Z Stop: Determines upper Auto Scale edge.

  • Values Animation: Sets the vertical animation type to be created when data change is detected:

      • Disable: Does not create an 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.

  • Data Nodes Animation: Sets the horizontal animation type to be created when number of data nodes change is detected.

      • Disable: Does not create an animation.

      • Timer: Creates data transition animation (from an old set of data to a new set) within the specified time set in Duration sec.

    • Duration sec.: Sets the duration of the animation in seconds for Timer mode.

      Note: When number of nodes is changes, scatter chart looks for added and removed nodes from their values, adds new nodes to the chart from zero width and resizes all nodes to their new size in specified duration.

  • Horizontal Alignment: Sets horizontal orientation to left, center or right.

  • Chart Width: Adjusts the chart width.

  • Container: Determines the container used for the scatter nodes.

  • DataZ SizeX: Allows Z Values to influence X scaling.

  • DataZ SizeY: Allows Z Values to influence Y scaling.

  • DataZ SizeZ: Allows Z Values to influence Z scaling.

  • Center Container: Centers each translated container.

  • Fit Width: Considers the width of the scatter node containers which means that the containers do not reach outside of the specified range.

  • Animate Position: Sets the translation type: None: no animation, Y: animates the container along the Y axis (suggestion: Scale Y + DataLabel for BarChart alike labeling).

  • Animate Scaling: Sets the scaling type: None: no scaling at all, XYZ: linear scaling in all directions, Y: scales in y direction only (->BarChart).

    • Relative Length: Provides each scatter node with its own 100% size (e.g. seven nodes equal 700%).

    • Const. Speed: Sets the same animation duration for each bar.

    • Total Length%: Sets the accumulated size of all scatter nodes in percent.

To Create a Scatter Chart

  1. Create a group and add the Sphere plug-in to it.

  2. Open the transformation editor and set the Scaling (locked) to 0.2.

  3. Add a material and/or a texture to the sphere.

  4. Set the group with the sphere to hidden.

  5. Create a new group and add the Scatter Chart plug-in to it.

  6. Open the Transformation Editor and set Position X and Y to -100.0.

  7. Open the Scatter Chart editor and set the following parameters:

    • Set the following DataY values: 10,20,30,20,50,60,80,45,20.

    • Set Width to 250.0.

    • Drag and drop the container with the Sphere to the Container placeholder.
