Radar Chart

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.
