images/download/thumbnails/95402949/ico_linechart.png
The Line Chart plug-in draws a line 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.

This page contains the following topics and procedures:

Line Chart Properties

  • Shared Mem.: Changes between Scene, Global and Distributed Shared Memory. Use Inactive memory to not forward any values via Shared Memory.

  • Specify X Values: Enables DataX input.

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

    • Key DataX: Determines Shared Memory key name for X values.

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

  • Key DataY: Determines Shared Memory key name for Y 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.

      Note: If the Line Stack plug-in is used, the following Line Chart properties need to be defined in the Line Stack plug-in.

  • DataX, -Y Fit: Enables data normalization.

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

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

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

    • DataX, -Y Fit Size:

      • Total: Scales the whole chart to the defined borders.

      • Current: Scales the current chart segment to the set borders.

    • DataX, -Y Detect Limits: Detects minimum and maximum of all values and scales them to adjusted Start and Stop. This option is used to upscale the interesting part of a chart - especially if there are only little changes between the data values.

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

    • DataX, -Y Start: Lower Auto Scale edge.

    • DataX, -Y Stop: 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: 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

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

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

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

  • Line Type:

    • Normal: Direct connections between entered values.

    • Spline: Interpolates extra values to chamfer the graph.

    • Constrained Spline: Same as Spline mode but with a different algorithm to prevent overshooting.

  • Chart Width: Adjusts line width (0 for 2D mode).

    • Tessellation Width: Sets tessellation length in spline modes.

  • Thickness: Adjusts line thickness (0 for 2D mode).

  • Depth: Adjusts line depth (0 for 2D mode).

  • Tessellation Thickness: Tessellates line thickness.

  • Tessellation Depth: Tessellates line depth.

  • Const. Thickness: Builds the geometry with a constant width.

    • Miter: Applies a miter cut-off to avoid huge peaks for small data point angles.

  • Selection: Specifies the Start- and Stop-type. Relative: 0%: 100%. Absolute: depends on your specified data. ID: Value ID starting from 0.

  • Start%, abs,: Determines starting point of the graph.

  • Stop%, abs,: Determines stop point of the graph.

  • Reposition Start: Translates the whole chart always to the same starting point.

  • Bevel: Activates Bevel mode.

    • Bevel Start: Chamfer start.

    • Bevel Stop: Chamfer stop.

    • Bevel Size%: Adjusts bevel’s size from 0 to 100.

    • Bevel Steps: Sets roundness via the number of segmentation steps.

      Note: A chamfer is a beveled edge connecting two surfaces.

  • RelativeMapping: Stretches texture to fit graph length.

  • Pos. Container: Translates every child container to a bar’s top.

    • Container Offset: Adds a certain offset to each container.

    • Value Dependent Pos.: Translates the container above or below the line in dependency on the data values.

    • Container Offset Z: Adds a Z axis offset to each container.

    • Center Container: Centers each translated container.

  • Pointer: You can use a container as a pointer and move it along the chart’s shape.

    • Container: This container represents your pointer.

    • Selection: Specifies the position-type. Relative: 0%: 100%. Absolute: depends on your specified data. ID: Value ID starting from 0.

    • Position%, abs,: Translates pointer by this parameter.

    • Offset: Adds an offset to the container’s position.

    • Normal Offset: Rotates the offset so that it is perpendicular to the chart’s surface.

    • Rotate: Rotates the container in dependency on the chart’s shape.

    • Offset Z: Adds a Z axis offset to the pointer.

    • Center Container: Uses the container’s center for translation and rotation.

  • Low Pointer: Activates the low pointer.

    • Container: Chooses a container for the pointer.

  • High Pointer: Activates the high pointer.

    • Container: Chooses a container for the pointer.

  • Start Pointer: Activates the Start Pointer.

    • Container: Chooses a container for the pointer.
