Radar Chart

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

mouse

mouseClicked

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.

.source	The component that fired this event
.button	The code for the button that caused this event to fire.
.clickCount	The number of mouse clicks associated with this event.
.x	The x-coordinate (with respect to the source component) of this mouse event.
.y	The y-coordinate (with respect to the source component) of this mouse event.
.popupTrigger	Returns 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.
.altDown	True (1) if the Alt key was held down during this event, false (0) otherwise.
.controlDown	True (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDown	True (1) if the Shift key was held down during this event, false (0) otherwise.

Customizers

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.
