一个或多个参与者未能绘制（）
这是我的代码我希望有一个与dashbord的combochart但我有这个错误：
一个或多个参与者未能画出（）×janv。 2013janv。 2013févr。 2013févr。 2013mars 2013mars 2013avr。 2013avr。 2013mai 2013mai 2013juin 2013juin 2013juil。 2013juil。 2013août2013août2013
!function($) { google.load('visualization', '1.1', {packages: ['corechart']}); google.load('visualization', '1', {packages: ['controls']}); google.setOnLoadCallback(initialize); function initialize(cityName) { // You can manipulate the variable response // Success! var query = new google.visualization.Query('http://api.XXX.com/XXX/datasource?table=montmorin'); query.setQuery("select (cost_reportings_timestamp), sum (cost_reportings_cost) group by (cost_reportings_timestamp) pivot ecoadmin_zone_name"); //Send the query with a callback function. query.send(drawDashboard); //console.log(response); } function drawDashboard(response) { // it's a good idea to include something like this to catch errors if (response.isError()) { alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage()); return; } var data = response.getDataTable(); console.log(data); var namePicker= new google.visualization.ControlWrapper({ controlType: 'ChartRangeFilter', containerId: 'filter_div', options: { // Filter by the date axis. filterColumnLabel: 'cost_reportings_timestamp', ui: { chartType: 'LineChart', chartOptions: { chartArea: { width: '90%' }, hAxis: { baselineColor: 'none' } }, // Display a single series that shows the closing value of the stock. // Thus, this view has two columns: the date (axis) and the stock value (line series). chartView: { columns: [0,1] } } }, //Initial range: 2010 to 2021 state: { range: { start: new Date(2012), end: new Date(2019) } } }) // Define a bar chart var pieChart = new google.visualization.ChartWrapper({ chartType: 'ComboChart', containerId: 'chart_div', options: { width: 400, height: 300, seriesType: 'bars', isStacked:'True', hAxis: { minValue: 0, maxValue: 60 }, chartArea: { top: 0, right: 0, bottom: 0 }, }, view: {columns: [0, 1, 2, 3]} }); var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard_div')). bind(namePicker, pieChart). draw(data); } }(jQuery); 你能解释一下吗??????
这是我的JSON的格式：
google.visualization.Query.setResponse({"version":"0.6","status":"ok","sig":"266867977","table":{"cols":[{"id":"ecoadmin_building_name","label":"ecoadmin_building_name","type":"string","pattern":""},{"id":"ecoadmin_zone_name","label":"ecoadmin_zone_name","type":"string","pattern":""},{"id":"cost_reportings_cost","label":"cost_reportings_cost","type":"number","pattern":""},{"id":"cost_reportings_timestamp","label":"cost_reportings_timestamp","type":"date","pattern":""}],"rows":[{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.0},{"v":new Date(2012,11,8)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.0},{"v":new Date(2012,11,9)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.453663},{"v":new Date(2012,11,10)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.458649},{"v":new Date(2012,11,11)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.44573},{"v":new Date(2012,11,12)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":1.09863},{"v":new Date(2012,11,13)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.429977},{"v":new Date(2012,11,14)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":1.13331E-4},{"v":new Date(2012,11,15)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.0},{"v":new Date(2012,11,16)}]},{"c":[{"v":"Mairie de Montmorin"},{"v":"Bureau de M. le Maire"},{"v":0.471569},{"v":new Date(2012,11,17)}]}
您的JSON的问题在于JSON表示中没有'table'属性， 'cols'和'rows'是'version'直接对等。 因此，您修复的JSON应如下所示：
google.visualization.Query.setResponse({ "version": "0.6", "status": "ok", "sig": "266867977", "cols": [{ "id": "ecoadmin_building_name", "label": "ecoadmin_building_name", "type": "string", "pattern": "" }, { "id": "ecoadmin_zone_name", "label": "ecoadmin_zone_name", "type": "string", "pattern": "" }, { "id": "cost_reportings_cost", "label": "cost_reportings_cost", "type": "number", "pattern": "" }, { "id": "cost_reportings_timestamp", "label": "cost_reportings_timestamp", "type": "date", "pattern": "" } ], "rows": [ {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.0}, {"v": new Date(2012, 11, 8)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.0}, {"v": new Date(2012, 11, 9)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.453663}, {"v": new Date(2012, 11, 10)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.458649}, {"v": new Date(2012, 11, 11)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.44573}, {"v": new Date(2012, 11, 12)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 1.09863}, {"v": new Date(2012, 11, 13)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.429977}, {"v": new Date(2012, 11, 14)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 1.13331E-4}, {"v": new Date(2012, 11, 15)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.0}, {"v": new Date(2012, 11, 16)}]}, {"c": [{"v": "Mairie de Montmorin"}, {"v": "Bureau de M. le Maire"}, {"v": 0.471569}, {"v": new Date(2012, 11, 17)}]} ] });
