问题描述



目前图表正在更新所有值。



现在我需要更新图表


  • 3个月
  • 6个月

  • 9个月

  • 12个月

  • 15个月
  • 18个月
  • li>


如何在javascript或jquery中做到这一点?

我已经创建了小提琴解释我的情况

http:// jsfiddle.net/Yq3DW/97/



这是html

 < select id =SelectPeriod> 
< option value =last3Months>过去3个月< / option>
< option value =last6Months>过去6个月< / option>
< option value =last9Months>过去9个月< / option>
< option value =last12Months>过去12个月< / option>
< option value =last15Months>过去15个月< / option>
< option value =last18Months>过去18个月< / option>
< option value =last24Months>过去24个月< / option>
< / select>

< div id =chart>< / div>

JS

  var calculation = [[实际值,目标值]],
结果= [[100,190],[115,190],[250,190],[23,190],[190 [190,190],[170,190],[170,190],
[100,190],[115,190],[250,190],[23,190],[190,190],
[115,190],[250,190],[23,190],[190,190],[170,190],[100,190],[115,190],
[250,190],[23,190], [190,190],[170,190]];

calculation = calculation.concat(result.sort(function(a,b){}));
var chart = c3.generate({
bindto:'#chart',
data:{
rows:calculation,
type:'bar',
}
});

这是我的定制,尝试

<$ p $($#$)$($#$)$ c3.generate({
data:{
rows:calculation
}
});
});

详细解释



我需要根据时间范围更新图表。



如果用户选择6个月下拉列表,我只需要显示6个月的图表。



目前整个24个月都在更新。

现在我需要对数据进行分类。

解决方案

<请参阅 http://jsfiddle.net/Yq3DW/99/



我更改了选项的,以指示每个应显示多少个月以及更改事件I slice 原始数组。我使用 + 1 将第3,第6等项目包含在数组中。

  $(#SelectPeriod)。change(function(evt){
var chartSelection = $(#SelectPeriod)。val();
var chart = c3.generate {
data:{
rows:calculation.slice(0,parseInt(chartSelection)+ 1),
type:'bar'
}
});
});


I need to update the chart based on time period.

currently chart is updating all values.

Now i need to update the chart by

  • 3 months
  • 6 months
  • 9 months
  • 12 months
  • 15 months
  • 18 months

how to do in javascript or jquery.??

i have created fiddle to explain my situation

http://jsfiddle.net/Yq3DW/97/

this is the html

<select id="SelectPeriod" >
    <option value="last3Months">Last 3 months</option>
    <option value="last6Months">Last 6 months</option>
    <option value="last9Months">Last 9 months</option>
    <option value="last12Months">Last 12 months</option>
    <option value="last15Months">Last 15 months</option>
    <option value="last18Months">Last 18 months</option>
    <option value="last24Months">Last 24 months</option>
</select>

<div id="chart"></div>

JS

     var calculation = [["Actual value","Targeted value"]],
    result = [[100, 190],[115,190],[250, 190],[23,190],[190, 190],[170,190],
[100, 190],[115,190],[250, 190],[23,190],[190, 190],[170,190],[100, 190],
[115,190],[250, 190],[23,190],[190, 190],[170,190],[100, 190],[115,190],
[250, 190],[23,190],[190, 190],[170,190]];  

    calculation = calculation.concat(result.sort(function (a, b) {  }));
    var chart = c3.generate({
        bindto: '#chart',
        data: {
            rows: calculation,
            type: 'bar',
        }
    });   

this is my customisation , trying

$("#SelectPeriod").change(function (evt) {
    var chartSelection = $("#SelectPeriod").val();
    var chart = c3.generate({
        data: {
            rows: calculation
        }
    });
});

in detail explanation

I need to update the charts based on time frame.

If user selects 6 months dropdown, i need to show only 6 months chart.

currently it is updating whole 24 months.

Now i need to categorise the data.

How to do it in javascript or jquery?? please help me.

Any help is appreciated

解决方案

See http://jsfiddle.net/Yq3DW/99/

I changed the value of options to indicate how many months each should show and in the change event I slice the original array. I use + 1 to include the 3rd, 6th, etc. item in the array.

$("#SelectPeriod").change(function (evt) {
    var chartSelection = $("#SelectPeriod").val();
    var chart = c3.generate({
        data: {
            rows: calculation.slice(0, parseInt(chartSelection) + 1),
            type:'bar'
        }
    });
});
