無法使用Google圖表創建完整的餅圖

Question

我一直在嘗試實現Google Graph和Dashboard，

這是我的代碼的片段，

     <script type="text/javascript">

            function drawVisualization(dataArray) {
                //                function drawVisualization() {
                // Prepare the data
                var data = google.visualization.arrayToDataTable(dataArray);
                // Define a category picker control for the Gender column
                var categoryPicker = new google.visualization.ControlWrapper({
                    'controlType': 'CategoryFilter',
                    'containerId': 'control2',
                    'options': {
                        'filterColumnLabel': 'Provider State',
                        'ui': {
                            'labelStacking': 'vertical',
                            'allowTyping': false,
                            'allowMultiple': false
                        }
                    }
                });

                // Define a Pie chart
                var pie = new google.visualization.ChartWrapper({
                    'chartType': 'PieChart',
                    'containerId': 'chart1',
                    'options': {
                        'width': 300,
                        'height': 300,
                        'legend': 'none',
                        'title': 'Demo Data Displayed',
                        'chartArea': {'left': 15, 'top': 15, 'right': 0, 'bottom': 0},
                        'pieSliceText': 'label'
                    },
                    // Instruct the piechart to use colums 0 (Name) and 3 (Donuts Eaten)
                    // from the 'data' DataTable.
                    'view': {'columns': [1, 5]}
                });

                // Define a table
                var table = new google.visualization.ChartWrapper({
                    'chartType': 'Table',
                    'containerId': 'chart2',
                    'options': {
                        'width': '300px'
                    }
                });

                // Create a dashboard
                new google.visualization.Dashboard(document.getElementById('dashboard')).
                    // Establish bindings, declaring the both the slider and the category
                // picker will drive both charts.
                bind([categoryPicker], [pie, table]).
                    //                    bind([pie, table]).
                // Draw the entire dashboard.
                draw(data);
            }

        </script>
// This is the dataArray [["DRG Definition","Provider State","Total Discharges","Average Covered Charges","Average Total Payments","id"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","AL","879","29855.3481218009","5857.17519906485","2"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","AZ","606","33581.3151824257","7034.48184806271","4"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","CO","255","33554.1607857647","6911.51372542745","6"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","DC","47","44919.3829785106","9241.59574459574","8"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","FL","2847","38464.4531085423","6145.54970143098","10"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","HI","24","27809.95833","10982.04167","12"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","ID","113","18150.97345","6457.23893819469","14"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","IN","1078","26888.4359918275","6597.5454545872","16"],["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","KY","728","22308.0645596154","6347.6085165467","18"],....

這里的問題是我的圖形（餅圖）確實生成，但是它只能部分加載，如果我從類別下拉列表中選擇1個值，則僅顯示其餅圖，我無法從圖表中看到其他值，希望有1個可以在這幫我

Answer 1

首先，正如我在對另一個問題的回答中提到的那樣，如果要使用PieChart，則必須將數字輸入為數字，而不是字符串。 例如，您需要更改此設置：

["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","AL","879","29855.3481218009","5857.17519906485","2"]

對此：

["039 - EXTRACRANIAL PROCEDURES W\/O CC\/MCC","AL",879,29855.3481218009,5857.17519906485,2]

修復此問題后，控件將完全按照您的設計工作：它在“提供者狀態”列上進行過濾。 使用您提供的示例數據，PieChart僅顯示一個切片，但這是因為每個狀態數據僅包含一行。 在此處查看基於您的代碼的工作示例： http : //jsfiddle.net/asgallant/tqB92/
