我有一张图表,它运行正常。但唯一的问题是,我想减少 Backbone.sync = function(method, model, options) {
var type = methodMap[method];
// Default options, unless specified.
_.defaults(options || (options = {}), {
emulateHTTP: Backbone.emulateHTTP,
emulateJSON: Backbone.emulateJSON
});
// Default JSON-request options.
var params = {type: type, dataType: 'json'};
// Ensure that we have a URL.
// if (!options.url) {
// params.url = _.result(model, 'url') || urlError();
// }
if (!options.url) {
if(model.urlExtended) {
// type is GET, POST...
// options are what you passed to fetch, save, etc.. as options
params.url = model.urlExtended(type, options);
} else {
params.url = _.result(model, 'url') || urlError();
}
}
... rest of Backbone.sync code..
如何做到这一点?
示例:我当前的图表的刻度从tick-size.
开始到0
,它计为100
个数字。(按10)如何将其减少到11
个数字例如从6
开始到以0
结尾 - 但不是100
重复10
重复20
,0
,{{1} },20
..?
这是我的代码:
40
答案 0 :(得分:1)
我更新了这样的刻度值:
$(function(){
var m = [80, 80, 80, 80]; // margins
var w = 300; // width
var h = 450; // height
var plan = 55;
var actual = 38;
var variation = plan - actual;
var data = [0,plan];
var data1 = [0,actual];
var x = d3.scale.linear().domain([0, 1.25]).range([0, w]);
var y = d3.scale.linear().domain([0, 100]).range([h, 0]);
var line = d3.svg.line()
.x(function(d,i) {
return x(i);
})
.y(function(d) {
return y(d);
})
var graph = d3.select("#graph").append("svg:svg")
.attr("width", w + m[1] + m[3])
.attr("height", h + m[0] + m[2])
.append("svg:g")
.attr("transform", "translate(" + m[3] + "," + m[0] + ")");
var yAxisLeft = d3.svg.axis()
.scale(y)
.tickValues(d3.range(0, 120, 20))
.tickSize(-w)
.orient("left");
graph.append("svg:g")
.attr("class", "y axis")
.attr("transform", "translate(-0,0)")
.call(yAxisLeft);
graph.append("svg:path").attr("d", line(data));
graph.append("svg:path").attr("d", line(data1));
//not able to fill the bg between 2 lines
var area = d3.svg.area()
.x(function(d, i) { return x(i) })
.y0(function(d, i) { return y(data[i]); })
.y1(function(d, i) { return y(data1[i]); })
graph.append("path")
.datum(data)
.attr("d", area)
.attr("fill", "brown")
.style("opacity", 0.5);
});
