SPC Individual Chart - Perspective

Perspective SPC Charts | Individual Chart

The Individual Chart presents the absolute difference between two consecutive values.

For SPC data analysis when:

grouping measurements into rational subgroups is not possible,
monitoring actual observations is preferred to viewing subgroup averages
the process distribution is very skewed or bounded.

The Perspective Chart component is in Ignition Designer | Perspective Component Palette.

Available in MES 3.81.7 RC1 and later

Installed with SPC Module

Viewing SPC Chart

	Sample Data	Table of samples showing data points. You can show or hide the table by setting the showTable property.
	Sample Details	Mouse-over a data point to display the statistical information configured for the chart and a timestamp.
	Primary Average Line Upper Control Limit Lower Control Limit	The purple line above shows the primary average by enabling showPrimaryAverage property, see below. The red lines above and below the midline depict the upper and lower control limits. Data points that land in between the upper and lower lines are known as common-cause variation.
	Data points outside of limits	Points outside of the limits, called special-cause variation. For information about configuration Signals and Rules, see SPC Signals.

Table Chart Scroll Locking

When the showTable property is set to True, the table chart scroll locking feature provides a user-controlled mechanism to either automatically navigate to the most recent data upon its arrival or maintain the current scroll position.

The scroll lock feature operates in two distinct modes, each with specific UI indicators and behavioral responses to new data.

This feature is available in versions:

MES 3.81.11 SP7 and later

MES 4.83.0 RC2 and later

State	Detailed Description
Locked	UI: The lock icon in the taskbar appears closed and filled. Behavior: The chart view is locked to the right, automatically jumping to the end of the table whenever new data is received. Tooltip: Hovering over the icon displays the text: "Allow Free Scrolling".
Free Scrolling	UI: The lock icon in the taskbar appears open and unfilled. Behavior: The chart maintains its current scroll position, even when new data is received. Tooltip: Hovering over the icon displays the text: "Lock Scrolling".

SPC Individual Chart in Ignition Designer

The Designer Perspective Component lists the chart. Once you add the chart to the design area, it displays and you have access to its properties in the Perspective Property Editor.

Component Properties

Properties affect the operation and look of the component. They can be set through the Perspective Property Editor in the Designer or through scripting.
