I want to set different width of dc.chart svg on different resolution,but media queries are not working.Is dc.chart supporting media queries or not? please suggest me solution for it as soon as possible.

The svg element is directly sized by dc.js, and since element-level styles override stylesheet-level styles, your media queries will have no effect.

What you want to do is set the size of the containing div (#chartCumulativeDVH or .dc-chart).

Then you have ~~two~~ at least three choices how to apply the size to the svg element that will be created:

Leave off the width and height as you show in your example. dc.js will automatically use the size of the container div if width and height are not specified. However, this will not work if anything else is in the div (or might show up there, like the filter and reset controls) because they will no longer be the same size, and the svg size can get out of control in these cases.
Set the size of the chart to match the div size, e.g. (using jQuery) something like chart .width($('#chartCumulativeDVH').innerWidth()) .height($('#chartCumulativeDVH').innerHeight())
Or, to base the width and height off the window size without using jQuery and without the media query, as we do in the resizing bar chart example: chart .width(window.innerWidth-20) .height(window.innerHeight-20)
