因此,我正在使用Rickshaw图形库,并且想知道如何动态地将点添加到图形中。
我有一个这样实例化的图:
@seriesData = [ [], [], [] ]
random = new Rickshaw.Fixtures.RandomData(150)
for (var i = 0; i < 50; i++) {
random.addData(self.seriesData)
}
@graph = new Rickshaw.Graph(
element: document.getElementById("chart")
width: 550
height: 300
renderer: 'area'
series: [
{
color: "#c05020"
data: self.seriesData[0]
name: 'One'
}, {
color: "#30c020"
data: self.seriesData[1]
name: 'Two'
}, {
color: "#2791d7"
data: self.seriesData[2]
name: 'Three'
}
]
)
@graph.render()
hoverDetail = new Rickshaw.Graph.HoverDetail(
graph: self.graph
)
legend = new Rickshaw.Graph.Legend(
graph: self.graph
element: document.getElementById('legend')
)
shelving = new Rickshaw.Graph.Behavior.Series.Toggle(
graph: self.graph
legend: legend
)
axes = new Rickshaw.Graph.Axis.Time(
graph: self.graph
)
axes.render()
我有这样的数据通过socket.io传入:
app.on('data',
(one, two, three) =>
// Dynamically add data points to graph
)
我想知道如何将这三个点添加到图形中。我找不到该库的任何好的文档。我知道它是建立在
d3.js
之上的,但是我不确定如何将这些方法合并到我的图形中。任何帮助,将不胜感激。
最佳答案
我设想了两种可以解决您的问题的方案:
。
var data = [
{
data: [ { x: 0, y: 120 }, { x: 1, y: 890 }, { x: 2, y: 38 }, { x: 3, y: 70 }, { x: 4, y: 32 } ],
color: "#c05020"
}, {
data: [ { x: 0, y: 80 }, { x: 1, y: 200 }, { x: 2, y: 100 }, { x: 3, y: 520 }, { x: 4, y: 133 } ],
color: "#30c020"
}
];
var graph = new Rickshaw.Graph( {
element: document.getElementById("chart"),
renderer: 'line',
height: 300,
width: 800,
series: data
} );
var y_ticks = new Rickshaw.Graph.Axis.Y( {
graph: graph,
orientation: 'left',
tickFormat: Rickshaw.Fixtures.Number.formatKMBT,
element: document.getElementById('y_axis'),
} );
graph.render();
$('button#add').click(function() {
data.push({
data: [ { x: 0, y: 200 }, { x: 1, y: 390 }, { x: 2, y: 1000 }, { x: 3, y: 200 }, { x: 4, y: 230 } ],
color: "#6060c0"
});
graph.update();
});
