极坐标系下的柱状图

[mm007008009]

我尝试了多个极坐标下的柱状图，发现，barWidth会被均分。

查询和尝试了多种避免均分的方法，仍然无法避免。

请确认这是否是bug，感谢！！！

示例代码：

option = {
    angleAxis: [{
        type: 'category',
        data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'],
        z: 11,
        polarIndex:0,
        boundaryGap :true,
    },{
        type: 'category',
        data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'],
        z: 10,
        polarIndex:1
    },{
        type: 'category',
        data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'],
        z: 9,
        polarIndex:2
    }],
    radiusAxis: [{
        polarIndex:0,
        type:'value',
    },{
        polarIndex:1,
        type:'value',
    },{
        polarIndex:2
    }
    ],
    polar: [{
        center:['200','600'],
        radius:100,
    },{
        center:['600','600'],
        radius:100,
    },{
        center:['600','300'],
        radius:100,
    }],
    polar1:[{
        center:['200','600'],
        radius:100,
    }],
    series: [{
        type: 'bar',
        // data:[[1,0,],[2,10],[3,20],[4,30]],
        data: [2, 2, 3, 4, 3, 4, 2,2],
        coordinateSystem: 'polar',
        name: 'A',
        stack:'a',
        polarIndex:0,
        // barWidth:30,
    },{
        type: 'bar',
        data: [1, 2, 3, 4, 1, 4, 1],
        coordinateSystem: 'polar',
        name: 'C',
        stack:'b',
        polarIndex:1,
        angleAxisIndex:1,
        radiusAxisIndex:1,
    },{
        type: 'bar',
        data: [1, 2, 3, 4, 1,4,1,1],
        coordinateSystem: 'polar',
        name: 'D',
        polarIndex:2,
    }],
};

sorry, I don't understand what you want? Can you tell us the expected performance you want?

I want to know why the barWidth of a histogram is not fixed in multiple polar coordinates.

[explorerNW]

from the source code, I found, the startAngle and endAngle calculate incorrect in function calRadialBar.And in each series, i set the barWidth: 40.but in the calRadialBar function, only the lastest series barWidth is useable.

[explorerNW]

In barLayoutPolar function, the variable of columnOffset,is incorrect, and i bug found, the stacks's is calculate incorrect in calRadialBar function.

This seems to be a bug.

@Ovilia i still get this problem in version echarts-4.2.1-rc3

you can try following options:

option = {
    angleAxis: {
        max: 5,
    },
    radiusAxis: {
        type: 'category',
        data: ['周一', '周二'],
        z: 10
    },
    polar: {
    },
    series: [{
        type: 'bar',
        data: [4, 4],
        coordinateSystem: 'polar',
        name: 'A',
        barGap: "-100%",
        barWidth: '60%',
        itemStyle: {
            normal: {
                color: '#dadada'
            }
        }
    }, {
        type: 'bar',
        data: [1, 2],
        coordinateSystem: 'polar',
        name: 'B',
        barWidth: '60%',
    }]
};

you will see category 'A' and 'B' barWidth is not equal to '60%',
and this problem only happen when barWidth large than '50%'.
