Google Chartsを使用するJSONからDataTableを作成し、いくつかの列を追加し、行を入力してから特定の列を選択するdatviewを作成します。Google Charts、DataViewは自分のDataTableのすべての列を見ることができません
GoogleのチャートAPIのdiplaysを実行すると：Invalid column index 6. Should be an integer in the range [0-4].
のDataTableがここ5.コードで、それに10列を持っていないので、これは、奇数です。ここで
function setoregonwkldbardata(){
var query = "SELECT Cluster, RAMCapacityGB, LHRAMCapacityGB, AvgVMRAMUsedGB, RAMUsedGB, NumVMs FROM clusterstat WHERE Location LIKE 'Oregon' AND Date = (SELECT MAX(Date) FROM clusterstat) ORDER BY Cluster ASC";
var urlencoded = encodeURI(sql2json+query);
var jsonData = $.ajax({
url: urlencoded,

async: false
