Distribution is essentially an interactive histogram. It divides objects in the map into five segments according to the value of selected indicator. It tells you how many objects (areas, dots, markers,..) belongs to specific value range.
Examine the distribution of your data
The shape of the histogram tells you how is your data distributed. The amount of objects (y-axis) is plotted on the total value range of selected indicator (x-axis).
The shape of histogram may vary depending on your data and they distribution. Take a look on three basic examples that may happen.
Example 1: No significant extremes
This distribution suggests that most objects correspond to medium values, while small portion of areas correspond to both low and high values.
Example 2: Extremes at the ends of the spectrum
This kind of distribution means that majority of objects corresponds to low values (e.g. generate little turnover), while only small number of objects corresponds to high values (e.g. generate big turnover).
Example 3: Missing columns in the spectrum
This distribution shows that some ranges of values do not correspond to any objects. It means, for example, that not a single object (e.g. district) has number of customers within that particular value range.
Change the range of segments
You can freely change the range of each of five segments depending on how you want your data to be distributed in the map. Hover the segment and drag the break to adjust the range or click the break to input exact value. Use "Reset" to reset do default setting.
You will get best results by adjusting the segments according to the distribution of the histogram.
Choose all objects from segment
Use "shift" and click into one segment to get the list of all objects in the segment. You can get deeper insight into these objects using other indicator value.
Hide segments from the map
Hovering a segments in the histogram will highlight all corresponding objects in the map. You can hide those objects from the map completely by clicking into the segment in block distribution. Please note, that it change the value of selected indicator. This allows you to examine only the narrow portion of data you are interested in.
You can also hide desired segments by clicking on the segment in legend.
Segments and intervals values
The segments in distribution operate as half-opened intervals. It means that one endpoint is included but not the other. The intervals are closed from the left side and open from the right. For example, in interval [25, 30) 25 is included but not 30. The only exception is the last segment on the right side of distribution. This one is always closed. It means that both endpoints are included. The same rules apply to segments in legend.
The values of breaks are calculated dynamically and acquires different values when you switch between different levels of granularity or when you select different objects from map. It is possible to set up static values of breaks in Distribution. Find out how to do it in Documentations for Developers.
Distribution as a filter
As you select some segment from Distribution it basically works as filter. It affects the indicator value and data in other block or indicators. Keep in mind, that it is temporary. Switch to Infopanel, Dashboard or other Indicator drill doesn't keep the settings.
