• Ready
• Started
To configure the command to be executed when this event occurs, go to Runtime tab. Find the Commands on Events section, check Enable Commands on Events, then configure the form below.
See Platform Services > Commanding > New: Execute Commands on Events for more details.
Commanding - Determines whether commands are enabled for this display. Use the CommandingName setting to specify a registration name. Click this checkbox if you intend to use Commanding with the current Heatmap control. You can also click on the button to reset the current setting.

You can also click on the button to reset the current setting.
Name - Name and unique identification of this type. This name must be equal to the name from the data source column Type (see the Type Binding configuration). Enter a name in the text entry field. You can also click on the button to reset the current setting.

Enter a distance function in the text entry field or click on the button to open the Data Browser to navigate to your source for a distance function.

You can also click on the button to reset the current setting. [Note: Minimal Value defines the diameter of the sample "stamp". In case of weighted average, the stamps must overlap to get a reasonable result. Zero Minimal Value ensures an expected result, but yields the worst performance. For a "Full" data set, it might be enough to pick the maximum distance to neighbor samples, i.e. the value of the distance function for: 1/max(w,h), where w, h is the width and height of the smallest rectangle defined by four samples. For sparse data, you should set it to zero to be safe.]
