Thirty bar charts per week lined up next to each other would be too much. A stacked bar chart gives us the total sales, but what if we wanted to compare within each week? We could make a line graph for each store and then plot all thirty on the same graph. That, too, would quickly get overcrowded with information. As weʼve seen, once we exceed about five or six, we start to run out of unique colours, shapes, thicknesses and so on. Graphing thirty at once becomes a mess.400300200100 1 2 3 4 5 6 7 8 9 10 11 12 Peter Gassner. Designing with Data - PDF. 13th August 2010. © Five Simple Steps.

They are basic line graphs split horizontally into a set number of bands. This example uses four bands, but they can contain as many as required. Each of the bands is coloured with an increasing intensity of blue. So far, this is no different than a standard line graph with some interesting shading. The next part is the Eureka! moment. Since we are really only interested in the outer edge of the line graph, why not collapse each of the bands on top of each other to save space?

By changing the colour of the shading, the graph appears to be stacking up the parts. There is nothing hiding behind any of the peaks so, unlike 3-D charts, nothing is being obscured. This works with both positive and negative values. Maybe in some weeks the shops were making a loss, which can be represented with a different colour, such as varying intensities of red.

The horizon graph works really well when large numbers of data sets need to be compared. Converting one line graph into a horizon graph does save some space, but now that we have this ribbon, we can stack more ribbons on top to get a quick view of all
