What is the Google Visualization API?
1. The Google Visualization API allows you to create charts and reporting applications over structured data and helps integrate these directly into your website.
What can I do with the Visualization API?
1. With the Google Visualization API, you can access structured data--created locally in your browser or retrieved from supported data sources in a simple tabular format. You can also implement your own data source as Visualization API data source and enable any Visualization-compliant visualization and/or application to access your data. The format is amenable to use by reporting, analysis or chart applications. You can thus visualize the data and/or add new functionality to applications, su...
Where can I find documentation for the Visualization API?
1. You can find the developer guide and all other related documentation at https://developers.google.com/chart/interactive/docs.
What is the difference between the Google Chart API and the Google Visualization API?
1. The Chart API provides a simple way to create image charts of various kinds by sending a formatted URL that includes both the data and chart configuration options to a Google server. The Chart API includes a closed set of charts with various options. The Chart API datasets are limited to the size of a URL (roughly 2K). The Visualization API provides a way to connect charts and data sources over the web and to publish them:
What data sources can I access using the Visualization API?
1. With the Visualization API you can access data locally from your browser by creating the API's standard DataTable format, or access any data source that supports the API. Well-known applications that already support the API are Google Spreadsheets and Salesforce.com on their Force.comdeveloper platform. You may also implement your own data as a Chart data source.
My application expects the data it receives to be in a specific format. How do I handle exceptions?
1. You can use the getNumberOfColumns() and getColumnType() methods of class google.visualization.DataTableto test that the data you get matches what you expect, and issue an error message for mismatches.
Why doesn't my chart appear?
1. First, check your JavaScript console. On Chrome, you can access the JavaScript console via Chrome->View->Developer->JavaScript Console, or Chrome->Tools->JavaScript Console. All modern browsers have a JavaScript console; you may need to poke around menus with names like "Advanced" or "Developer Tools" to find it.Hopefully, the console leads you immediately to the problem. Sometimes, however, it'll be hard to translate the console message to the underlying cause. Here are some common pitfalls:
Why are my months and days off by one?
1. Google Charts uses JavaScript, which uses zero-based indexing. The first day of the month is 0, and the months range from 0 (January) to 11 (December). If your code assumes one-based indexing, subtract one before putting the your data into a JavaScript date object.
Why do my charts work in some browsers but not all?
1. We recommend caniuse.com for a trove of information about browser incompatibilities. With Google Charts, there are sometimes problems in Internet Explorer 8 and earlier, for two reasons: IE8 doesn't support SVG, so Charts fails over into VML, which is more limited. IE8's JavaScript doesn't allow trailing commas in lists.
