I´m using Echarts for data visualisation, documentation is not clear to me ;(

What I need is basically change of width and height of chart. I tried to change height of pie-chart div but as a consequences only div height is changed without change of chart dimensions. If anyone know solution i would really appreciate.

 <div class="card grid-stack-item-content cd-example" id="dashboard-header">
                            <div class="card-header container-fluid">

Reset to default 2

Try in your option variable;

responsive: true,
maintainAspectRatio: false

I found a solution, basically the radius mand is used to configure the graph

 radius: [20, 180],

docs here: https://echarts.apache/en/option.html#series-pie.emphasis

inside your series

      ...
      emphasis: {
                scale: true, <----- 
                scaleSize: 20,  <-----
                label: {
                    show: true,
                    fontSize: '30',
                    fontWeight: 'bold'
                },
                itemStyle: {
                    // Color in emphasis state.
                    color: 'blue',
                 },
            },
    ...

You can set the width in your option variable, for example:

width: '50%'

docs: https://echarts.apache/en/option.html#series-pie.width
