XY Chart

About 5 min

The XY Chart is a component that is similar to the Line Chart; however, the X-axis on XY Chart is assigned to one of the data channels rather than to time. This allows you to map two parameters against each other to evaluate interdependencies.

Supported data types

The following table outlines data types supported by XY Chart component:

Channel Type	Supported?
Tag	🟢
Asset (Attributes)	🟢
Timeframe (Attributes)	🟢
Tag Search	⚫
Asset Search	⚫
Timeframe Search	⚫

Quick Start

To quickly start using the XY Chart component, drag and drop it onto the work area. Search for the data you want to visualize and map it onto the component:

The first piece of data either dragged onto the component, or defined within the attribute mapping window as seen will be the reference x-axis for all additional attached data.

Generic Settings

Each IOTA Component has a set of generic settings. For more information, expand the corresponding section below:

Workspace

These settings are applicable to the whole view.

Grid Properties

The grid is provided for convenience when developing dashboards as visual guides and snapping capability.

By default the work area grid is enabled and can be customized or even disabled in this menu.

Property Name	Description
Grid Color	Color of the grid
Grid Size	Size of the grid step
Snap to Grid	Enable/Disable snapping to the grid
Show Grid Lines	Show the grid as lines
Show Grid Dots	Show the grid as dots

Align Controls

The Align controls provides a means to align and distribute selected objects on the display.

Align Objects

You can align several components horizontally using the Align-left, Align-center or Align-right controls
You can align several components vertically using the Align-top, Align-vertical-center or Align-bottom controls

Distribute Objects

You can distribute several components on the vertical/horizontal axis by selecting them (select at least 3 components) and pressing Align-vertical/Align-horizontal
You can make all the selected components the same width/height by selecting them and pressing Adjust Width/Adjust Height

Tips

Hold the Ctrl button to select several components. The eldest component is used as a reference.

Anchor Points Options

The anchor points are eight squares around an object that allow you to resize the object. The anchor point options allow you to define the appearance of the anchor points.

Property Name	Description
Reference Point Color	Sets the color of the reference point (see Rotation and Position for more details)
Anchor Points Color	Sets the color of the rest of the seven anchor points
Point Options Color	Sets the color of the point options (only for Line and Bezier Curve)
Show Point Options	Show/Hide the point options

Locked View Options

These options define the appearance of the component border in the locked view for the selected component.

Property Name	Description
Active Border Fill	Sets the fill color of the border
Active Border Width	Sets the width of the border

Variable

Every component has a unique variable name. This variable name can be used to reference the component in multi-state configurations and other scripts.
On creation, every component is given a default name. This can be overwritten to be more user-friendly. To do so simply overwrite the value in the variable input field.

Arrange / Remove

Send Backward - move object one layer down
Bring Forward - move object one layer up
Send to Back - place object under all layers
Bring to Front - place object above all layers
To send/bring objects to the front/back use the first four buttons.
Any set of components can be deleted by either using the button or delete/del keyboard keys.

Rotation and Position

Reference Anchor Point - allows you to select one of the anchor points as a reference so that you can set an Angle (clockwise) of incline relative to this point. By default the reference anchor point is the top left corner. You can also rotate the component by dragging one of the yellow corner points.
You can set the position of the component by setting the X and Y coordinates relative to theReference Anchor Point and the top-left corner of the work area.
You can drag any of the anchor points to change the width and height of the component, or you can set it manually by editing the Width and Height boxes.
Set Lock Aspect Ratio so that while changing width and height, the component width to height ratio stays the same
Transform allows you to view the component as a mirror or a reflection of itself

XY Chart Settings

Component Specific

The Component Specific section provides options for modifying various properties for XY Chart.

Data Join : defines how the X and Y data joined
- Interpolated : For each X timestamp (and value), a corresponding Y value will be calculated (interpolated) with the same timestamp
- Recorded : Only values with matching X and Y timestamps are shown
- Plotted : Same as Recorded with Plotting Optimization

Plotting Optimization

Plotting Optimization allows to to enhance performance by excluding (not fetching) unnecessary for visualization values, e.g when the number of values for the period is higher than the number of pixels that the X or Y scale has.

Scales / Cursors

The Scales / Cursors section allows you to control the appearance of the scales and cursors of the chart.

X-Scale

Type : change the type of the scale(s) by selecting one of the following:
- Single - one scale for all channels

- UOM - each unique UOM on the chart has it's own scale
Position: change the position of the scale(s) by selecting one of the following:
- None - don't show scale
- Top - show X-scale(s) at the top of the chart
- Bottom - show X-scale(s) at the bottom of the chart
- Distributed - distribute multiple scales between the Top and Bottom of the chart
Height: sets the distance of the X-Scale from the top or bottom. For multiple scales the Height sets the distance to the closest scale.
Inside: shows the scale inside of the chart area when checked
Min/Max Level : defines Min. / Max. scale level

Y-Scale

Type : change the type of the scale(s) by selecting one of the following:
- Single - one scale for all channels
- Individual - an individual scale for each channel on the chart
- UOM - each unique UOM on the chart has it's own scale

Format

The Format section provides options for customizing displayed information. The Component area of the XY Chart is divided into four sub-areas: Legend, Controls, Chart and Time.

Chart Layout

The Chart settings allow you to modify the layout of the component by moving and resizing sub-areas.

Chart Controls Area Alignment

You can change the alignment of the control buttons within the Controls section.

Timescale Area Alignment

You can change the alignment of the time controls within the Time section.

Transpose : check this box to transpose the time controls (horizontal to vertical and back)

Info

Horizontal alignment works for the transposed time area, and vertical alignment is for the normal time area (not-transposed).

Legend Layout

The legend arranger allows you to change the legend's layout for: Value, Label, Timestamp, UOM and Controls.
To display a property, drag it to the desired location within the grid. Once placed, you can align the property both vertically and horizontally using the controls underneath the grid.

Info

If you select the legend position as top, bottom, or center, you can only use the horizontal alignment options. If you select the legend position as right or left, you can only use the vertical alignment options.

The following options are available for customizing your legend:

H-Padding : defines the vertical padding
V-Padding : defines the horizontal padding

Legend Data Format

The following options are available for customizing your legend:

Label Source: defines the source for the label
- Name: the label is set to the name of the channel/attribute
- Channel Label: the label comes from channel/attribute mapping if trained
- Path: the label is set to the asset path plus the name of the attribute (works only for assets)
- AssetPath: the label is set to the asset path
- DataReference: works for PI AF data sources. if the channel is an attribute of Pi Point data reference- show the data reference configuration (i.e. pi data archive and tag) in a format \pidataarchive\tagname - the format is specific to pi
- Description : the label is set to the description of the channel/attribute
- Custom : the label is set to the Custom Label field
Path Levels: defines the path level fo the label if Label Source is set to Path or Assetpath
Custom Label allows to set a custom Label
Custom UOM : allows to define custom Units of Measure (UOM)

By default, the legend colors are transparent and show the assigned channel color. To revert back to this setting, simply choose the transparent option. To configure the channel colors, refer to the Channel section in Generic Settings.

The Toggle Synchronization button allows you to synchronize all the component properties to a desired color.

When the Toggle Synchronization button is disabled in Legend Colors, you can change the color of each property one by one.

If you want all the legend properties to have the same color, enable the synchronization mode
by clicking on the Toggle Synchronization button. In this mode, a change to any legend property color will automatically adjust all other
legend properties to the same color.

Note

The Legend Colors section is common among many components, so it is described using general visual examples, which may differ slightly from one component to another. However, the logic and behavior stays the same.

The Tooltip Setting provides data reference for PI AF attributes and descriptive statistics when user interacts with a component by hovering over it.

Show Current Value : Shows Current Value
Show Archive Values : Shows Archive Values, the number can be set in Number Values
Show Summaries : Shows Summaries for set Time Range Interval (can be set in seconds (s), minutes (m), hours (h), days (d), weeks (w), months (mo), years (y))

Summary Types :

Average : the average value in the set period
Minimum: the minimum value in the set period
Maximum: the maximum value in the set period
PercentGood: the percent good value in the set period
StdDeviation: The standard deviation of the value in the set period
PStdDeviation: The percent standard deviation of the value in the set period
Total: The sum of the values in the set period
