Description |
Property name |
Shows the names of custom properties defined for this column. Custom properties are metadata that can be used when searching for columns using the following search syntax: <Property name>:<Value>. For example, MyCompany.Property:Property1. Some types of data require specific properties and values to be treated correctly by Spotfire. An example is map columns which require the property mapchart.columntypeid, with the Value Geometry, XMax, XMin, YMax, YMin, XCenter or YCenter set on the different kinds of columns used when viewing WKB data in a map chart. See Configuration of Geographical Data for Map Charts for more information. Another example is chemical structure data, which requires the ContentType property to be set to chemical/x-mdl-molfile for the structure column and a "LeadDiscovery.Column" property with particular values defined for ID columns and search columns. See the TIBCO Spotfire Lead Discovery Installation Manual for details. Custom column properties can also be used for drawing lines in some of the visualizations. |
