我有一个要求，即根据树视图复选框选择值轴需要更新。我使用了4个值为4的复选框。当我检查第一个项目时，应该更改相应的值轴.3其他轴应处于不可见状态。
在这里，我尝试了一些代码并进行了更新。
代码：
<div id="treeview"></div>
<div id="example" class="k-content">
<div class="chart-wrapper">
<div id="chart"></div>
</div>
</div>
var valueAxes = [
{ name: "KM",visible:false,
title: { text: "KM" ,visible:false}
},
{ name: "Miles Per Gallon",
title: { text: "Miles Per Gallon" }
},
{
name: "Miles",
title: { text: "Miles " }
},
{
name: "liters per 100km",
title: { text: "liters per 100km" }
}
];
function createChart() {
$("#chart").kendoChart({
legend: {
position: "top"
},
series: [{
type: "column",
data: [20, 40, 45, 30, 50],
stack: true,
name: "on battery",
color: "#003c72"
}, {
type: "column",
data: [20, 30, 35, 35, 40],
stack: true,
name: "on gas",
color: "#0399d4"
}, {
type: "area",
data: [30, 38, 40, 32, 42],
name: "mpg",
color: "#642381"
}, {
type: "area",
data: [7.8, 6.2, 5.9, 7.4, 5.6],
name: "l/100 km",
color: "#e5388a"
}],
valueAxes:valueAxes,
categoryAxis: {
categories: ["Mon", "Tue", "Wed", "Thu", "Fri"],
axisCrossingValues: [0, 0, 10, 10]
}
});
}
$(document).ready(function() {
createChart();
$("#treeview").kendoTreeView({
checkboxes: {
checkChildren: true
},
dataSource: [{
id: 1,
text: "Value axis",
expanded: true,
items: [{
id: 2,
text: "KM"
},
{
id: 3,
text: "Miles Per Gallon"
},
{
id: 4,
text: "Miles "
},
{
id: 5,
text: "liters per 100km"
}]
}]
}).data("kendoTreeView");
$("#treeview").on("change", function (e) {
var chart = $("#chart").data("kendoChart");
var checkedSeries = [];
$("#treeview").find(":checked").each(function() {
var nodeText =$(this).parent().parent().text();
$.each(valueAxes, function(index, valueAxes) {
if (valueAxes.name == nodeText) {
checkedSeries.push(valueAxes);
checkedSeries.visible==="true";
checkedSeries.title.visible===true;
}
});
});
chart.options.valueAxes = checkedSeries;
chart.refresh();
});
});

为方便起见，我首先加载所有图表轴。它按你的要求工作....

是的，可以一次绑定和取消绑定值轴和系列
更改您的脚本如下
var valueAxes = [
{
name: "KM", labels: {
format: "{0}"
}, min: 0,
max: 9,
title: { text: "KM" }
},
{
name: "Miles Per Gallon", labels: {
format: "{0}%"
}, min: 0,
max: 5,
title: { text: "Miles Per Gallon" }
},
{
name: "Miles", labels: {
format: "{0}%"
},
title: { text: "Miles " }
},
{
name: "liters per 100km", min: 0,
max: 1,
title: { text: "liters per 100km" }
}];
var series = [{
type: "column",
axis: "KM",
data: [20, 40, 45, 30, 50],
stack: true,
name: "KM",
color: "#003c72"
}, {
type: "column",
data: [20, 30, 35, 35, 40],
axis: "Miles Per Gallon",
stack: true,
name: "Miles Per Gallon",
color: "#0399d4"
}, {
type: "column",
data: [30, 38, 40, 32, 42],
axis: "Miles",
name: "Miles",
color: "#642381"
}, {
type: "column",
axis: "liters per 100km",
data: [7.8, 6.2, 5.9, 7.4, 5.6],
name: "liters per 100km",
color: "#e5388a"
}];
function createChart(inputValueAxes, inputSeries) {
$("#chart").kendoChart({
legend: {
position: "top"
},
series: inputSeries,
valueAxes: inputValueAxes,
categoryAxis: {
categories: ["Mon", "Tue", "Wed", "Thu", "Fri"],
axisCrossingValues: [0, 0, 10, 10]
}
});
}
$(document).ready(function () {
createChart(valueAxes, series);
$("#treeview").kendoTreeView({
checkboxes: {
checkChildren: true
},
dataSource: [{
id: 1,
text: "Value axis",
expanded: true,
items: [{
id: 2,
text: "KM"
},
{
id: 3,
text: "Miles Per Gallon"
},
{
id: 4,
text: "Miles "
},
{
id: 5,
text: "liters per 100km"
}]
}]
}).data("kendoTreeView");
$("#treeview").on("change", function (e) {
var chart = $("#chart").data("kendoChart");
var checkedSeries = [];
var checkedAxes = [];
if ($("#treeview").find(":checked").length !== 0) {
$("#treeview").find(":checked").each(function () {
var nodeText = $(this).parent().parent().text();
$.each(valueAxes, function (index, valueAxes) {
if (valueAxes.name == nodeText.trim()) {
checkedAxes.push(valueAxes);
checkedAxes.visible = true;
}
});
$.each(series, function (index, series) {
if (series.name == nodeText.trim()) {
checkedSeries.push(series);
}
});
});
createChart(checkedAxes, checkedSeries);
}
else {
createChart(checkedAxes, checkedSeries);
}
});
});
答案 2 :(得分：1)
我编辑了你的代码，因为我可以通过在if = length == - 1的条件下调用creatChart（checkedAxes）函数来绑定和取消绑定valueaxis，那时系列不会更新。
$("#treeview").on("change", function (e) {
var chart = $("#chart").data("kendoChart");
var checkedSeries = [];
var checkedAxes = [];
if ($("#treeview").find(":checked").length !== -1){
$("#treeview").find(":checked").each(function () {
var nodeText = $(this).parent().parent().text();
$.each(valueAxes, function (index, valueAxes) {
if (valueAxes.name == nodeText) {
checkedAxes.push(valueAxes);
checkedAxes.visible = true;
}
});
$.each(series, function (index, series) {
if (series.name == nodeText) {
checkedSeries.push(series);
}
});
});
chart.options.series = checkedSeries;
chart.options.valeAxes = checkedAxes;
chart.refresh();
}
createChart(checkedAxes);
});
但如果我在没有调用creatChart（checkedAxes）函数的情况下尝试，则会更新绑定到图表的系列。
$("#treeview").on("change", function (e) {
var chart = $("#chart").data("kendoChart");
var checkedSeries = [];
var checkedAxes = [];
if ($("#treeview").find(":checked").length !== -1){
$("#treeview").find(":checked").each(function () {
var nodeText = $(this).parent().parent().text();
$.each(valueAxes, function (index, valueAxes) {
if (valueAxes.name == nodeText) {
checkedAxes.push(valueAxes);
checkedAxes.visible = true;
}
});
$.each(series, function (index, series) {
if (series.name == nodeText) {
checkedSeries.push(series);
}
});
});
chart.options.series = checkedSeries;
chart.options.valeAxes = checkedAxes;
chart.refresh();
}
});
我一次都没有得到这两种情况。希望你找到解决办法。
干杯， 快乐的编码...
