问题 I am constructing a horizontal bar plot in nvd3 with domain names as x-labels. The domain names, while not too long, are longer than the amount of space given to them. How do I increase the amount of space given to an axis in nvd3 ? jsfiddle example here. 回答1: Apparently, you can specify your own margins. For example: var chart = nv.models.multiBarHorizontalChart() .margin({top: 30, right: 10, bottom: 30, left: 90}) // increase the left margin .x(function(d) { return d[0]; }) .y(function(d) {
