Olap Question / Problem


User (Legacy)

Background:

Using ChartFx Trial 6.2 with Olap Extension.

I have an mdx query returning 1 measure and 3 dimensions (Time, Geography,

PropertyType). Under the Time dimension are Quarters 1 - 4. Under

Geography, I have any number of regions and under each region I have any

number of cities. Under property type, I have 3 property types that each

can have any number of sub types.

With this scenario, capturing the click event and reading the series is just

about useless because it is returned out of context.

When the user clicks on a series, I want to know which dimension, level,

etc. are being used to display the data in the chart.

Alternatively, I can try trapping when the user clicks in the analysis

bar(expands node, de-selects dimension, selects dimension), and build a

collection of items referring to the data displayed. I can't determine how

to do this.

The real issue is determining at any one time what the series values on the

chart are referring to.

Any help appreciated.

We just added a new method called GetDimensionStates, this method receives a 

series and a point and returns a collection of DimensionStates.

The DimensionState class exposes 3 string properties: Dimension, Level and

Value that will let you know all the data for a particular bar/marker. Note

that if the current level of a dimension is the top level summarization, you

will receive a value of (All). This is the string returned by the OLAP

engine. If you need more information about a dimension or a level you can

use

olap.Dimensions[dimState.Dimension]

olap.Dimensions[dimState.Dimension].Levels[dimState.Level]

Also note that this method will return as many DimensionStates as Dimensions

in your MDX statement.

For tree dimensions you must ignore the Level property as a tree-like

dimension can show multiple levels simultaneously.
