EChart 設置折線圖圓角

EChart 設置折線圖圓角: 只需要在series中設置"barBorderRadius": 0 即可.

"series": [
    {
        "name": "seriesName",
        "itemStyle": {
            "normal": {
                "barBorderRadius": 0
            },
    },
    "type": "bar",
    "stack": "mxstack",
    "data": "seriesData"
    }
]
