I need to calculate the difference between six time series in three ways:

  • Time Series are: Kamel, Dumper, Graben, Traktor, Generator
  • Methods are: Euclidean distance, Manhattan distance and maximum distance

For example, I show the differences between these time series for Euclidean distance in a table like this:

enter image description here

(I have two more such tables.) Now I want to visualize these tables in one diagram, with a different color for each method. What data visualization method should I use?

Who is the audience? What is the key message that you want the audience to get from the graphic? Why are the numbers, their magnitude and significant digits the right ones to use? – EngrStudent Jul 13 '14 at 14:51
The radar plot is good for comparing equivalent metrics on different classes. You could have six lines on 3 radar plots. It might be more informative. – EngrStudent Jul 13 '14 at 15:00

The most natural representation would be three heat maps with the same coloring (small multiples).

If the distance scales are too different for a single color scale, you can either use different colors for each or standardize the measures to put them on the same scale.

If there is some consistent ranking of pairs, then overlaid line plots or dot plots may help show the pattern. However, it's no good in these examples with random data.

If you want to color code the values in a nice color scale you can try a heatmap plot (see this link). If you are still interested in different colors for each method you can try grouped bars; that will allow you to specify separate colors for each bar (see link).
