Is there a way to limit the brushing height - say 50% of y axis (only from Y axis 0 - 250, brushing should work) ? Example fiddle
JS Code:
var hitslineChart = dc.barChart("#chart-line-hitsperday");
var data = [
{date: "12/27/2012", http_404: 2, http_200: 190, http_302: 100},
{date: "12/28/2012", http_404: 2, http_200: 10, http_302: 100},
{date: "12/29/2012", http_404: 1, http_200: 300, http_302: 200},
{date: "12/30/2012", http_404: 2, http_200: 90, http_302: 0},
{date: "12/31/2012", http_404: 2, http_200: 90, http_302: 0},
{date: "01/01/2013", http_404: 2, http_200: 90, http_302: 0},
{date: "01/02/2013", http_404: 1, http_200: 10, http_302: 1},
{date: "01/03/2013", http_404: 2, http_200: 90, http_302: 0},
{date: "01/04/2013", http_404: 2, http_200: 90, http_302: 0},
{date: "01/05/2013", http_404: 2, http_200: 90, http_302: 0},
{date: "01/06/2013", http_404: 2, http_200: 200, http_302: 1},
{date: "01/07/2013", http_404: 1, http_200: 200, http_302: 100}
];
var ndx = crossfilter(data);
var parseDate = d3.time.format("%m/%d/%Y").parse;
data.forEach(function(d) {
d.date = Date.parse(d.date);
d.total= d.http_404+d.http_200+d.http_302;
});
var dateDim = ndx.dimension(function(d) {return d.date;});
var hits = dateDim.group().reduceSum(function(d) {return d.total;});
var minDate = dateDim.bottom(1)[0].date;
var maxDate = dateDim.top(1)[0].date;
hitslineChart.width(500)
.height(200)
.dimension(dateDim)
.group(hits)
.x(d3.time.scale().domain([minDate,maxDate]));
dc.renderAll();
