# See best distance and worst distance at a glance

I need to show the shortest distance among other distances on a map for a given point.

I was thinking of a shading of colors from green to red but there are too much lines displayed (it will always be that number (~13-15 lines) ).

I will add a board to summarize these distances but I need to give a good idea indicator with the map only).

Do you think I have to put in green the shortest distance and in red the longest distance, and the others in green, or do you have another solution?

• You'll want to consider red-green color blindness, too. Commented Apr 6, 2016 at 13:52

Did you take a look at how Google maps shows their shortest path?

The shortest path is highlighted with a strong color and the other options in a less prominent color (grey on Google maps).

Also an indicator shows how long each path will take to reach the destination.

When adding colors just make sure you choose colors and a thickness that will make both types of lines stands out from the rest of the map.

• You're so right ! I based all of my ux on google maps ux and here maps ux, and didn't think of them for that function... I don't know why I wanted colors so much... As a gift for your help, take a look and laugh at my new jamaican map imgur.com/gHYM6on :-) Thanks ! Commented Apr 6, 2016 at 11:21

Assuming that you only want to show distances in a straight line from a single point (I don't think airplanes fly the same way as crows do), I think the most informative way to display this would be using circles (or arcs) that radiate from your point of origin. It is difficult to compare the lengths of lines when they are branching out in different directions, so by drawing a circle it gives you a much easier way to compare between different lines.

Then you can apply the visual styling suggested by @nuwa to indicate the shortest path, and maybe even do some graduation in colour intensity until you get to the longest or furtherest path.

But in the first instance, think about how to present the information logically, then think about enhancing it visually, not the other way around!
