Factors relate to the different areas displayed in an Areas map.
Each factor specifies how the areas are to be graded when the user selects the factor.
If there is only one factor, it will be selected automatically (and there is no need to show the factors box).
Factors can be selected from the Details box (see the Details page) provided the corresponding columns are included in the list of details columns.
For each factor:
The Column of a factor must correspond exactly to a column in the map’s location data. It must have numeric data.
The Label is how the factor will be referred to in the map page.
Click on the “Edit Factor” button manage the detals of a factor.
Drag factor blocks up and down to change the order in which they will appear to the user on the map page.
This page has the settings for a selected factor.
Factors control the colour coding of areas in an Areas map.
Enter a Column for the factor. This must contain numeric data.
Enter a Label for the factor
You can choose between three different methods of colouring the areas (the Colour Gradient)
- Gradient – click to choose one of the available gradients
- Shades – click on the colour box to use all shades of the colour
- Blocks – Enter a series of colours with from/to value bands for each
Lower and Upper are both optional but specify the value below/above which the values found in the data will be overridden. If your data ranges from 13 to 72 but you want to show a percentage, set lower as 0 and upper as 100. Note that if in the case you set lower to 50 the colour gradient would still work from 13 to 100.
Optionally, set Reverse in order to show the colour gradient in reverse. This has no effecton Blocks as you are determining the ranges.
