我在使用chartjs创建的条形图上显示图例时遇到问题。该文档讨论了一个图例模板，但我似乎找不到一个很好的例子来说明如何将其实现到图中。下面是我用来生成图表的代码。 varrandomScalingFactor=function(){returnMath.round(Math.random()*100)};varbarChartData={labels:["Item1","Item2","Item3","Item4","Item5","Item6","Item7","Item8","Item9","Item10","Item11","Item12","Item13","Ite

我正在使用chartjs(条形图)来显示一些数据。我正在尝试将数据动态添加到datasets数组，但它不起作用。例如，假设我在数据集数组中有2个对象，我动态创建了这个对象并试图将他插入数据集(从Chrome控制台)在页面加载并且图表已经启动之后。vare={fillColor:"#efefef",strokeColor:"#efefef",highlightFill:"#efefef",highlightStroke:"#efefef",data:[randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),ran

我的html文档中有这个脚本，它使用Chart.js创建图表。其中的数据是手动插入的(数据集中的标签和数据)。数据集中的数据现在是随机生成的数字。但我需要以某种方式将它与我的MySQL数据库连接起来。varrandomScalingFactor=function(){returnMath.round(Math.random()*100)};varbarChartData={labels:["January","February","March","April","May","June","July","January","February","March","April","May",

我正在尝试将静态数据转换为使用数据库结果。我将使用MySQL和PHP。示例代码:varrandomScalingFactor=function(){returnMath.round(Math.random()*100)};varlineChartData={labels:["January","February","March","April","May","June","July"],datasets:[{label:"MyFirstdataset",fillColor:"rgba(220,220,220,0.2)",strokeColor:"rgba(220,220,220,1)"
