When you create an eSpatial heat map, default colors are used – ranging from yellow to red – to highlight levels of data values within a specified region:
However, you can easily customize these colors (you can go as wacky as you want!):
How to change heat map colors
In the Legend window, hover over the heatmap dataset (it’s the one with the polygon shape – not the marker – beside it), and select Style & Color:
This should open the Color by Value window, which allows you to customize the ranges & colors or shades in a heat map. Each part of the Color by Value window, and how to use it, is explained below.
- Select the field in the heatmap whose colors you wish to change.
- Add or delete the number of shades/color differentiators based on levels of occurrence of selected data.
- Click dropdown on each box to adjust/reselect colors.
- Indicates last six colors used.
- Select color range.
- Select specific shade of color – chosen from range slide – by clicking within color box.
- Indicates current or last color used.
- Indicates new color selected.
- If you’re looking for a color with a specific hexadecimal color value, enter it here and hit “return”
Once happy with your choice of new colors, click “select”. In the main map window, you’ll see a preview of what the new heat map looks like.
You can also save that color palette to be used on other maps by clicking the “Store Range” button on the styling menu.
Finally, click save on the top of the Styling Panel to save your map.
