问题
I have a number of bar charts created using dc.js.
In the default behavior, the user can click+drag on any of them to update the crossfilter. How can I make a chart "display-only"? That is, the chart will update when other components update the crossfilter, but the user can't select data in the "display-only" chart to update the crossfilter.
