The Region button allows you to display data for one area. Click the Region button to show a list of all areas. Once an area is selected the menu closes, the other data are hidden and the maps zoom in to the selected area.

2.4 Legend

Each map is controlled by its own legend box. This shows the key to the map, including the colours used and their values and allows you to make changes to the map’s appearance.

Using the legend you can:

Change the colours on the map, and the classes used by clicking the pen icon.

View the strategic health authority (SHA) or geographical region boundaries by clicking the blue checkbox next to 'Strategic health authorities' or 'Geographical region'. The regions will then be outlined in red.

View a more detailed map with names of towns etc by clicking the checkbox next to 'Background Mapping'. This is only shown when zoomed into the map.






2.5 Map

The map shows the geographical boundaries for either PCTs, local authorities or top level local authorities in England depending on which dataset you are looking at. The organisational area which you have selected will be highlighted on the map. The map shows visually any geographical concentrations for particular indicators.

2.6 Area list

The area list shows the names of all areas and both values being displayed on the maps. Click the title bar to sort the list by name, Map 1 value or Map 2 value.

The magnifying glass icon can be used to zoom and centre the maps on the selected area.



2.7 Scatter plot

The scatter plot chart shows the correlation between the two indicators you have selected. The r-squared score shows whether or not there is a correlation between the two indicators; the closer to 1, the more of a correlation there is. You may find it helpful to use the Advanced Data Selector if you are looking at correlation, as it will allow you to compare indicators from different themes. Use Advanced Data Selector.
