Rickshaw - js chart library: Need strings instead

问题:

I am using rickshaw(http://code.shutterstock.com/rickshaw/) and want to have strings on one of the axes of the graph instead of numbers. Is it possible to do that? If so, how?

回答1:

Your own formatter can be defined and be used

Rickshaw.Fixtures.Number.myFormat =  (y) ->
  if (y == val)
    return 'somestring';
  else
    return ''some other string';

Use this as:

yAxis = new Rickshaw.Graph.Axis.Y
  graph: graph
  tickFormat: Rickshaw.Fixtures.Number.myFormat


graph.render()
