我正在尝试创建一个交互式的剑道图表。有三个系列:CAPITAL,FUEL和OM。每个系列都有三个数据值:PROPANE,DIESEL和ELECTRIC。
我尝试做的是在更改时连接文本框以更新PROPANE =>剑道图的CAPITAL值并更新图表。由于某种原因,当我这样做时,改变的列被绘制在图表之外的某个未知高度(没有双关语)。
这是javascript:
// chartSeries Index constants
var CAPITAL = 0;
var FUEL = 1;
var OM = 2;
var seriesData = {
capital: {
propane: 24200,
diesel: 25100,
electric: 34400
},
fuel: {
propane: 37783,
diesel: 44969,
electric: 7520
},
om: {
propane: 24960,
diesel: 24960,
electric: 15600
}
}
$(document).ready(
function () {
createChart();
});
$(document).bind("kendo:skinChange", createChart);
function createChart() {
$("#chart").kendoChart({
chartArea: {
width: 600,
height: 400
},
title: { text: "Lift Truck Ownership Cost Comparison" },
legend: { visible: false },
seriesDefaults: {
type: "column",
stack: true
},
series: [
{
name: "Capital Costs",
data: [seriesData.capital.propane, seriesData.capital.diesel, seriesData.capital.electric],
color: "#56B5FC"
}, {
name: "Fuel",
data: [seriesData.fuel.propane, seriesData.fuel.diesel, seriesData.fuel.electric],
color: "#E5DB14"
}, {
name: "O & M",
data: [seriesData.om.propane, seriesData.om.diesel, seriesData.om.electric],
color: "#14D314"
}
],
valueAxis: {
max: 100000,
line: { visible: false },
minorGridLines: { visible: true }
},
categoryAxis: {
categories: ["Propane", "Diesel", "Electric"],
majorGridLines: { visible: false }
},
tooltip: {
visible: true,
template: "#= series.name #: #= value #"
}
});
}
$(document).on("change", "#propaneCapitalCost", function() {
var chart = $("#chart").data("kendoChart");
var temp = $("#propaneCapitalCost").val();
chart.options.series[CAPITAL].data = [temp, 25100, 34400];
chart.refresh();
});
和html:
<style>
.emissionHeader {
font-weight: bold;
margin-bottom: 5px;
}
.emissionBottomBorder {
border-bottom: thin solid #615A39;
margin: 20px;
padding: 10px;
width: 200px;
}
.emissionLabel {
width: 75px;
text-align: right;
float: left;
margin-right: 3px;
}
.emissionTextBox {
width: 100px;
}
</style>
<div style="margin: 20px">
<div style="margin-bottom: 20px"><h2>@ViewBag.Title</h2></div>
<div id="dataEntry" style="float: left">
<div class="emissionBottomBorder">
<div class="emissionHeader">Adjust Capital Costs</div><div class="newline"></div>
<div class="emissionLabel"><label class="k-label">Propane:</label></div>
<input id="propaneCapitalCost" type="text" class="k-textbox emissionTextBox" />
<div class="newline"></div>
</div>
</div>
<div id="example" style="width: 600px; height: 400px; float: left">
<div class="k-content">
<div id="chart"></div>
</div>
</div>
</div>
奇怪的是,如果我将onchange方法更改为以下内容,则重绘错误似乎不存在:
$(document).on("change", "#propaneCapitalCost", function() {
var chart = $("#chart").data("kendoChart");
//var temp = $("#propaneCapitalCost").val();
chart.options.series[CAPITAL].data = [10000, 25100, 34400]; // Value hard coded
chart.refresh();
});
我完全不知道差异在哪里。公平地说,我绝不是js专家。这是某种奇怪的闭合还是什么?
答案 0 :(得分:3)
我过去遇到过这个问题,基本上图表需要一个数字,.val()
的{{1}}给你一个字符串。
我建议用几种方法来纠正但使用textbox
函数。
Number()
