用适当的值在nvd3.js中创建图形 [英] create graph in nvd3.js with proper values
问题描述
我想针对特定用户显示针对日期的图形计数。我想水平显示日期并垂直计数。但我不明白该怎么做。
我的json数据如下:
[key:0,values:[[1374517800000,2]]},182398:{key 182398, 值:[[ 1375295400000, 2],[ 1374517800000, 2],[ 1374604200000, 12],[ 1374431400000, 1], [ 1375122600000, 4],[ 13752.09亿, 19]]}, 185271:{ 键: 185271, 值:[[ 1374604200000, 2], [1374517800000,1]]]
和 var chart;
nv.addGraph(function(){
chart = nv.models.cumulativeLineChart()
.x(function(d){return d [0]})
.y (函数(d){return d [1]})
.color(d3.scale.category10()。range())
.clipVoronoi(false);
chart.xAxis
.tickFormat(function(d){
return d3.time.format('%x')(new Date(d))
});
chart.yAxis
.tickFormat(d3.format(',。1%'));
d3.select('#cumulative_line_chart svg')
.datum (stageArr)
//.transition().duration(500)
.call(chart);
// TODO:找出一个自动完成此操作的好方法
nv.utils.windowResize(chart.update);
//nv.utils.windowResize(function(){d3.select('#chart1 svg')。call(chart)});
chart.dispatch.on('stateChange',function(e){nv.log('New State:',JSON.stringify(e));});
return chart;
} );
现在在这种情况下,我的第一个问题是日期显示不正确(我将日期转换为strtotime ),然后concat 000与日期,例如 1375295400000 = strtotime(23-07-2013)。000
并且这种转换发生在php中)。
第二个问题是在y轴上我想显示整数像2,12,4,19(根据上面的json数据)等
所以请指导我如何做到这一点。
提前致谢。
更新:
抱歉,它不是d3.js,而是nvd3.js。
寻找像这样的东西?而此处是cde的工作版本
nv.addGraph(function(){
var chart = nv.models.lineChart()。margin({
top:30,
right :20,
bottom:50,
left:45
})。showLegend(true).tooltipContent(function(key,y,e,graph){
return'<在'+ y +'/ p''
});
$处的h3'+ key +'< / h3>'+'< p& b $ b chart.xAxis.tickFormat(function(d){
return d3.time.format('%x')(new Date(d))
});
d3.select('#lineChart svg')
.datum(data)
.transition()。duration(500)
.call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
data = [{
values:[{
x:1025409600000,
y:2
},{
x:1028088000000,
y:4
},{
x:1030766400000,
y:1
},{
x:1033358400000,
y:3
},{
x:1036040400000,
y:0
} ,{
x:1038632400000,
y:3
}],
key:正弦波,
}]
希望它有帮助。
I am using nvd3.js first time in my php code.
I want to show a graph count against date for particular user. I want to show the date horizontally and count vertically. But I did not understand how to do that.
My json data is like:["key":"0","values":[["1374517800000","2"]]},"182398":{"key":"182398","values":[["1375295400000","2"],["1374517800000","2"],["1374604200000","12"],["1374431400000","1"],["1375122600000","4"],["1375209000000","19"]]},"185271":{"key":"185271","values":[["1374604200000","2"],["1374517800000","1"]]]
and
var chart;
nv.addGraph(function() {
chart = nv.models.cumulativeLineChart()
.x(function(d) { return d[0]})
.y(function(d) { return d[1]})
.color(d3.scale.category10().range())
.clipVoronoi(false);
chart.xAxis
.tickFormat(function(d) {
return d3.time.format('%x')(new Date(d))
});
chart.yAxis
.tickFormat(d3.format(',.1%'));
d3.select('#cumulative_line_chart svg')
.datum(stageArr)
//.transition().duration(500)
.call(chart);
//TODO: Figure out a good way to do this automatically
nv.utils.windowResize(chart.update);
//nv.utils.windowResize(function() { d3.select('#chart1 svg').call(chart) });
chart.dispatch.on('stateChange', function(e) { nv.log('New State:', JSON.stringify(e)); });
return chart;
});
Now in this case my first problem is date is not showing properly(I converted the date to strtotime() and then concat 000 with the date e.g 1375295400000 =strtotime("23-07-2013")."000"
and this conversion is happening in php).
Second issue is in y axis I want to show the integer like 2,12,4,19(as per above json data) etc.
So please guide me how to do that.
Thanks in advance.
UPDATE: Sorry to say that it is not d3.js but it is nvd3.js.
Looking for something like this ? And here is a working version of the cde
nv.addGraph(function () {
var chart = nv.models.lineChart().margin({
top: 30,
right: 20,
bottom: 50,
left: 45
}).showLegend(true).tooltipContent(function (key, y, e, graph) {
return '<h3>' + key + '</h3>' + '<p>' + e + '% at ' + y + '</p>'
});
chart.xAxis.tickFormat(function (d) {
return d3.time.format('%x')(new Date(d))
});
d3.select('#lineChart svg')
.datum(data)
.transition().duration(500)
.call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
data = [{
"values": [{
"x": 1025409600000 ,
"y": 2
}, {
"x": 1028088000000 ,
"y": 4
}, {
"x": 1030766400000 ,
"y": 1
}, {
"x": 1033358400000 ,
"y": 3
}, {
"x": 1036040400000 ,
"y": 0
}, {
"x": 1038632400000 ,
"y": 3
}],
"key": "Sine Wave",
}]
Hope it helps.
