Cleanup MDX Data – Logi Analytics

Plugin Description

Traditionally, MDX queries are used to retrieve data from OLAP cubes for viewing in our OLAP Grid or OLAP Table elements. However, the data retrieved can also be used with any of our other visualization elements, such as DataTables and Charts. When used for non-OLAP purposes, special characters such as square brackets and periods need to be removed from the data first. This plug-in cleans the data in a datalayer of the special characters. The download includes the plug-in .dll, a readme file, and an example report definition. (.NET)
