Description

Radar charts, also known as web charts, spider charts, spider plots, and a few other names, display a dataset as a two dimensional polygon. The plot is arranged as a set of spokes with equal angles between them. Each spoke represents a value axis for the variable it corresponds to. Each dataset is then drawn as a connected polygon, where the points of the polygon are arranged on the spokes according to their value. Each row of the dataset has a minimum and maximum column -- these values are used to determine the scale of the spoke for that variable, with the midpoint representing the desired value.

The intended use of radar plots is to display realtime information in such a way that outliers can be quickly identified. This can be an efficient way to convey if a process is running on-spec or off-spec at a glance.

The radar chart gets its data from a dataset. Each row in the dataset will become a single variable (spoke) on the chart. The dataset must have a columns labeled "Value", "Min", and "Max"; other columns will be ignored. To display realtime data on a radar chart, you can use a cell-update binding to bind individual values to tag values. You can also drop tags onto a radar chart, with the EngMin binding to min and EngMax binding to max. If there are no existing cell-update bindings, the tags will replace existing data, otherwise the tags will be added to the end of the dataset. Alternatively, you can have realtime information stored by a transaction group to a database table, and drive the radar chart's dataset with a query binding.

Event Handlers

This event signifies a mouse click on the source component. A mouse click the combination of a mouse press and a mouse release, both of which must have occurred over the source component. Note that this event fires after the pressed and released events have fired.

.sourceThe component that fired this event
.buttonThe code for the button that caused this event to fire.
.clickCountThe number of mouse clicks associated with this event.
.xThe x-coordinate (with respect to the source component) of this mouse event.
.yThe y-coordinate (with respect to the source component) of this mouse event.
.popupTriggerReturns True (1) if this mouse event is a popup trigger. What constitutes a popup trigger is operating system dependent, which is why this abstraction exists.
.altDownTrue (1) if the Alt key was held down during this event, false (0) otherwise.
.controlDownTrue (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDownTrue (1) if the Shift key was held down during this event, false (0) otherwise.

This event fires when the mouse enters the space over the source component.

.sourceThe component that fired this event
.buttonThe code for the button that caused this event to fire.

.popupTriggerReturns True (1) if this mouse event is a popup trigger. What constitutes a popup trigger is operating system dependent, which is why this abstraction exists.
.altDownTrue (1) if the Alt key was held down during this event, false (0) otherwise.
.controlDownTrue (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDownTrue (1) if the Shift key was held down during this event, false (0) otherwise.

This event fires when the mouse leaves the space over the source component.

.sourceThe component that fired this event
.buttonThe code for the button that caused this event to fire.
.clickCountThe number of mouse clicks associated with this event.
.xThe x-coordinate (with respect to the source component) of this mouse event.

.controlDownTrue (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDownTrue (1) if the Shift key was held down during this event, false (0) otherwise.

This event fires when a mouse button is pressed down on the source component.

Fires whenever a bindable property of the source component changes. This works for standard and custom (dynamic) properties.

.newValueThe new value that this property changed to.
.oldValueThe value that this property was before it changed. Note that not all components include an accurate oldValue in their events.
.propertyNameThe name of the property that changed. NOTE: remember to always filter out these events for the property that you are looking for! Components often have many properties that change.
Examples

The following shows that the Motor 4 Amps are higher than the maximum allowed for Motor 4. In this example each motor has an independent min and max value for its amps. The radar chart allows an operator to quickly assess a group of independent variables to determine if anything is out of its specifications.
