Membuat DataTable
Semua diagram memerlukan data. Diagram Alat Google Diagram memerlukan data untuk digabungkan dalam class JavaScript
yang disebut google.visualization.DataTable. Class ini ditentukan di library Google
Visualization yang Anda muat sebelumnya.
DataTable adalah tabel dua dimensi dengan baris dan kolom, yang masing-masing memiliki
jenis data, ID opsional, dan label opsional. Contoh di atas membuat tabel berikut:
jenis: string
label: Topping
type: number
label: Slice
Jamur
3
Bawang Bombay
1
Zaitun
1
Zukini
1
Pepperoni
2
Ada beberapa cara untuk membuat DataTable; Anda dapat melihat daftar dan perbandingan
setiap teknik di DataTables dan
DataViews. Anda dapat mengubah data setelah menambahkannya, serta menambahkan, mengedit, atau menghapus kolom dan baris.
Anda harus mengatur DataTable diagram dalam format yang diharapkan oleh diagram: misalnya, Diagram batang dan Diagram lingkaran memerlukan tabel dua kolom
dengan setiap baris mewakili irisan atau batang. Kolom pertama adalah label irisan atau batang, dan
kolom kedua adalah nilai irisan atau batang. Diagram lain memerlukan format tabel yang berbeda dan mungkin lebih kompleks. Lihat dokumentasi diagram Anda untuk mempelajari format data yang diperlukan.
Daripada mengisi tabel sendiri, Anda dapat mengkueri situs yang mendukung protokol Datasource Chart Tools--misalnya, halaman Google Spreadsheets. Dengan menggunakan objek google.visualization.Query, Anda dapat mengirim kueri ke situs dan menerima objek DataTable terisi yang dapat diteruskan ke diagram. Baca topik lanjutan

kueri.

Google Chart Tools charts require data to be wrapped in a JavaScript\nclass called `google.visualization.DataTable`. This class is defined in the Google\nVisualization library that you loaded previously.\n\nA `DataTable` is a two-dimensional table with rows and columns, where each column has\na datatype, an optional ID, and an optional label. The example above creates the following\ntable:\n\n| type: string label: Topping | type: number label: Slices |\n|-----------------------------|----------------------------|\n| Mushrooms | 3 |\n| Onions | 1 |\n| Olives | 1 |\n| Zucchini | 1 |\n| Pepperoni | 2 |\n\nThere are several ways to create a `DataTable`; you can see a list and comparison of\neach technique in [DataTables and\nDataViews](/chart/interactive/docs/datatables_dataviews). You can modify your data after you add it, and add, edit, or remove columns and\nrows.\n\nYou must organize your chart's `DataTable` in a format that the chart expects: for\ninstance, both the [Bar](/chart/interactive/docs/gallery/barchart#Data_Format) and [Pie charts](/chart/interactive/docs/gallery/piechart#Data_Format) require a two-column\ntable where each row represents a slice or bar. The first column is the slice or bar label, and the\nsecond column is the slice or bar value. Other charts require different and possibly more complex\ntable formats. See your chart's documentation to learn the required data format.\n\nRather than populate a table yourself, you could instead query a website that supports the Chart\nTools Datasource protocol--for example, a Google Spreadsheets page. Using the\n`google.visualization.Query` object, you can send a query to a website and receive a\npopulated `DataTable` object that you can pass into your chart. See the advanced topic\n[Querying a Datasource](/chart/interactive/docs/queries) to learn how to send a\nquery. \n[**Next: *Customizing the\nChart***](/chart/interactive/docs/basic_customizing_chart)\n\nMore Information\n----------------\n\n- [DataTables and DataViews](/chart/interactive/docs/datatables_dataviews)\n- [DataTable reference documentation](/chart/interactive/docs/reference#DataTable)\n- [Querying a Datasource](/chart/interactive/docs/queries)"]]
