One objective of making the graphics in the neighbourhoods quite simple, is that we are able to shrink them down and make them small. This allows us create small tile maps that are still readable. This in turn enables us to view and compare multiple maps simultaneously. Here we show maps for different crime types concrently in ways that may help us compare geographic patterns.
Again, today is set to and you can move the date and one month at a time using these grey buttons, or the buttons at the bottom.
Try changing the date to see how crime patterns vary over time.
We can configure these sophisticated maps in multiple ways, but we'd like you to experiment to produce maps that combine information in ways that suit you. In the graphics that follow we have have add a slider that allows you to vary the strength of colour used to show the NPUs - it's opacity.
Use the slider to vary the strength of colour (opacity) used to show the NPUs.
What level works well for you? Is there a mid-point between NPU legibility and signal legibility that enables you to see both?
Here we have the same maps, but rather than having a coloured shape we use cell colour to show where signals occur and the direction. These maps contain less information, but may be clearer to read, and we may be able to shring them down further to consider more information.
Are the maps still legible if we make them smaller?
This consideration of designs for Comparing Multiple Maps concludes our investigation into the redesign of SPC charts in a geographical context.
