The dashboard provides a visual representation of how your areas compare against each other.
The colours on the dashboard provide you with a quick and easy representation of which of your areas have the highest / lowest values compared to the other custom areas that you have created.
It is important to note there are fundamental differences between the colour scale on the dashboard compared with the colour scale on the maps.
The areas are shaded in three colours which represent high, medium or low values. The methodology used to distribute the areas into the colour bands takes the highest and lowest value across your custom areas and then creates three bands which equally span that range.
Take the example below, looking at Cancer prevalence. The highest value in the table is 3.3 and the lowest is 1.5.
Therefore the value bands are as follows:
Note that these are equally sized bands so the difference between the lower and upper threshold of each band is 0.6 in this case. In cases where there are decimal figures involved the figures in the dashboard are rounded to 1 decimal point.
When you change which areas are displayed, the colours will update to reflect how the selected areas compare against each other. The figure for the national average is not included in the creation of the value bands.
