geo3D和bar3D混合使用下bar数据中的最小值的柱子高度为0

[xujunpro2]

在geo3D场景下，bar3D的最小值的柱子高度始终为0，除非设置minHeight，但minHeight也不能随便设置，目前我是通过在bar data中额外增加一个数值为0的数据来实现自动计算最小值的bar高度。 附上代码：

            function loadMap(){
                $.get('shanghai2.json',function(geoJson){
                    //console.info(geoJson);
                    echarts.registerMap('shanghai2',geoJson);
                    var option = {
                                geo3D: {
                                    boxWidth:'60', //三维场景中的宽度
                                    map: 'shanghai2',
                                    itemStyle: {
                                        color: '#1d5e98',
                                        opacity: 1,
                                        borderWidth: 0.4,
                                        borderColor: '#000'
                                      },

                                    viewControl: {
                                        distance: 50,
                                        panMouseButton: 'left',
                                        rotateMouseButton: 'right'
                                    },

                                },

                                series:[
                                    {
                                        type: "bar3D",
                                        coordinateSystem: 'geo3D',
                                        barSize: 1, //柱子粗细
                                        shading: 'lambert',
                                        opacity: 1,
                                        bevelSize:0.3,
                                        label:{show:false,formatter:'{b}',distance:0},
                                        minHeight:0,
                                        data:[
                                            {'name':'a',value:[121.58569335937501,30.908948861695676,20]},
                                            {'name':'b',value:[121.34569335937501,31.008948861695676,10]},
                                            {'name':'c',value:[121.77569335937501,31.008948861695676,30]}
                                        ]

                                    }
                                ]
                    };
                    var chartDiv = document.getElementById('chartDiv');
                    var myChart = echarts.init(chartDiv);   
                    myChart.setOption(option);
                });
            }

Hi @xujunpro2 . Thanks for using ECharts. Please do not open the same issues, which may be a burden for us to deal with. And you should not paste all the json data in your description, which makes the page too long to read. On the other hand, you should follow the issue template and provide online demo on http://gallery.echartsjs.com/editor.html or http://jsfiddle.net . Please edit your issue and @pissang will have a look at it then.

@pissang 另外那个重复提交是当时github网站出了问题导致的，并非我有意为之，对造成你们工作的困扰，表示歉意：）

[xujunpro2]

@pissang hi，刚才已经在editor提交了bug 的demo，网址是:https://gallery.echartsjs.com/editor.html?c=xXXHUfZ27Q&v=1 请注意name为‘a’的bar，值为10，但高度明显和另外两个柱子不成比例，我猜想是echarts把data中的最小值的bar的高度设置成了0
