# Value Distribution Filter

The value distribution filter acts in a very similar way to the Individual Probe Value Filter except that instead of using the probe values directly it sorts all of the values for each data store and coverts them into a percentage position within the total distribution of values for that DataStore.

This allows you to select, for example, the top 10% of values for a given data store. You can also filter across multiple stores, so you could select probes which were in the bottom 5% of values in at least 2 of 3 DataStores. This independence from the actual values being used allows for more powerful comparative filters.

## Options

- You need to select one or more DataStores from the list on the left. Data Sets are shown in red and Data Stores are shown in Blue.
- You can select an upper and a lower limit for the range of values you want to include. The limits you enter should be expressed as percentages of the distribution (eg 5% to 95%). You only have to specify one of these values. If you leave the lower value blank then anything under the upper cutoff will pass. If you leave the upper value blank then anything above the lower cutoff will pass.
- Finally you can choose in how many of your selected DataStores a probe needs to fall within your defined range in order to be included in the final list.
