爲了減少從數據庫中提取的數量，我一次獲取所有數據，然後使用不同視圖爲其定製更多圖表。在這種情況下，我有10列的數據表（從0到9），並希望顯示列0作爲X軸，1作爲AreaChart和另外兩列作爲組合圖上的行。如果我取4列的話，Everithing會奏效。第7列與view.setColumns Google給出錯誤信息"Invalid column index 7. Should be an integer in the range [0-4]."爲什麼索引只有0-4 !!! ???谷歌圖表 - 剪裁視圖 - 列索引0-4
這是它的樣子：
google.charts.load('current',{callback:init,'packages':['corechart'],'language':'hr'});
function init()
{
var data = new google.visualization.DataTable();
data.addColumn('date','Datum');
data.addColumn('number','Vrijednost');
data.addColumn('number','Relativna promjena');
data.addColumn('number','Kontinuiranost promjene');
data.addColumn('number','Prosjek obični u preth. 5 dana');
data.addColumn('number','Prosjek težinski u preth. 5 dana');
data.addColumn('number','Trend prema preth. 5 dana');
data.addColumn('number','Prosjek obični u preth. 10 dana');
data.addColumn('number','Prosjek težinski u preth. 10 dana');
data.addColumn('number','Trend prema preth. 10 dana');
data.addRows([
