Question

In the example here,

http://dimplejs.org/examples_viewer.html?id=lines_horizontal_grouped_stacked

How can I add x-labels of month, like just above "Black Mesa" and "Aperture"?

Answer 1

You can just verify the previous example which was already solved for two X-axis labels and the URL is:

Dual X-axes for line Graphs using SVG

and also you can just add two CategoryAxis which is much simple such that:

myChart.addCategoryAxis("x", "Month"); 
myChart.addCategoryAxis("x","Owner");
