### What problem does this feature solve? If I click on a "line" created by "coords" in a serie of type "lines", I can't know what "coords" index is clicked : for example : ``` var mousePosition = null; $.get( ROOT_PATH + '/data/asset/geo/MacOdrum-LV5-floorplan-web.svg', function (svg) { echarts.registerMap('MacOdrum-LV5-floorplan-web', { svg: svg }); option = { tooltip: { triggerOn: 'none' }, geo: { map: 'MacOdrum-LV5-floorplan-web', roam: true }, series: [ { name: 'Route', type: 'lines', coordinateSystem: 'geo', geoIndex: 0, polyline: true, lineStyle: { color: '#c46e54', width: 5, opacity: 1, type: 'dotted' }, tooltip: { trigger: 'item', position: function (pos, params, dom, rect, size) { return mousePosition; }, formatter: function (params) { return params.seriesName; } }, data: [ { coords: [ [61.58708083147317, 386.87942320312504], [61.58708083147317, 72.8954315876116], [258.29514854771196, 72.8954315876116] ] } ] } ] }; myChart.setOption(option); } ); myChart.on('mouseover', 'series.lines', function (params) { console.log('MOUSE', params) mousePosition = [params.event.offsetX, params.event.offsetY]; myChart.dispatchAction({ type: 'showTip', seriesIndex: params.seriesIndex, dataIndex: params.dataIndex }); }); myChart.on('click', 'series.lines', function(params) { console.log('I DON\'T KNOW WHICH "coords" index is clicked') }); ``` ### What does the proposed API look like? what it would be best: 1. if I click on the line (or mouseover) generated by coords on a type "line**s**" series, 2. the "params" response should have a property "coords" which give the 2 coords between the line 3. eg. coords: `coords: [ [61.58708083147317, 386.87942320312504], [61.58708083147317, 72.8954315876116] ]` -- This is an automated message from the Apache Git Service.
