我正在使用 gridstack 开发一个应用程序,我想使用 RGraph 库将多个图形(线条和仪表)放在不同的容器中。

我无法使图形填充容器的宽度和高度。此外,当我更改大小时,我希望图形适应容器。

我有一个例子:

代码 JSFiddle

$(document).ready(function ()
    {
 var data = [[4,5,8,11,15], [1,3,2,5,9]];
var tips = ['a','b','c','d','e','yf','yh','tt','hh','ll'];

var line = new RGraph.Line('cvs', data)
    .set('tooltips', tips)
    .set('gutter.left', 50)
    .draw();
    });
 #canvas{
width: 100% !important;
 max-width: 100% !important;
height: 70% !important;
  align-content:center;
  vertical-align:middle;
/*position:static;*/
}

#cvs {
    width: 100%;
    height: 100%;
}

您需要创建一个函数来重置和重绘线条,然后在窗口调整大小和小部件更新时触发(change在 gridstack 中的事件上)。确保不要使用额外的样式,因为它们实际上会妨碍您的结果。我已经更新了您的示例以调整窗口大小。当您调整小部件大小时它不会更新,但如果您调整窗口大小,您会看到图表继续填满整个小部件。
