当动态加载图表时,x 轴比例正在增加到 0.2。我想让比例增加 1 (1,2,3,4) 等而不是 0.2 (0.0, 0.2, 0.4, 0.6) 等。
有人可以帮忙吗?
这是我的代码:
$(document).ready(function(){
// Some simple loops to build up data arrays.
var cosPoints = [];
var j = 0;
var k = 0;
for (var i=0; i<2*Math.PI; i+=0.4){
cosPoints.push([i, Math.cos(i)]);
j = i;
}
var sinPoints = [];
for (var i=0; i<2*Math.PI; i+=0.4){
sinPoints.push([i, 2*Math.sin(i-.8)]);
k = i;
}
var powPoints1 = [];
for (var i=0; i<2*Math.PI; i+=0.4) {
powPoints1.push([i, 2.5 + Math.pow(i/4, 2)]);
}
var powPoints2 = [];
for (var i=0; i<2*Math.PI; i+=0.4) {
powPoints2.push([i, -2.5 - Math.pow(i/4, 2)]);
}
var plot1 = $.jqplot('chart1', [cosPoints, sinPoints],
{
title:'Line Style Options',
// Series options are specified as an array of objects, one object
// for each series.
series:[
{
// Change our line width and use a diamond shaped marker.
lineWidth:2,
markerOptions: { style:'dimaond' }
},
{
// Don't show a line, just show markers.
// Make the markers 7 pixels with an 'x' style
showLine:false,
markerOptions: { size: 7, style:"x" }
}
]
}
);
//in every 5s interval replot the graph with newData (new random data)
var intervalId = setInterval(function() {
var newData1 = new Array();
var newData2 = new Array();
newData1 = cosPoints;
newData2 = sinPoints
//remove the first element from the data array
newData1[0].shift();
newData2[0].shift();
//add a new element to the end of the array
j = j+0.4;
k = k+0.4;
newData1[0].push([j, Math.cos(j)]);
newData2[0].push([k, 2*Math.sin(k-.8)]);
plot1.series[0].data = newData1[0];
plot1.series[1].data = newData2[0];
plot1.resetAxesScale();
plot1.replot();
}, 1000);
});
