推荐答案

该谷歌图表API允许你提供一个网址给谷歌的服务，这反过来又返回图表图像。因为数据可以从黑莓智能手机通过并在BlackBerry智能手机产生相应的图表图像此功能是黑莓智能手机是有用的。

The Google Chart API allows you to provide a URL to the Google service, which in turn returns a chart image. This capability is useful from the BlackBerry smartphone because data can be passed from the BlackBerry smartphone and generates a corresponding chart image on the BlackBerry smartphone.

在这里，你可以做聊天的类型

here are the type of the chat you can do

下面是在谷歌API定义的聊天类型。

Here are the chat types defined in Google API.

public static final String LINE_C = "lc";
public static final String LINE_S = "ls";
public static final String LINE_XY = "lxy";
public static final String BAR_HORIZONTAL_STACKED = "bhs";
public static final String BAR_VERTICAL_STACKED = "bvs";
public static final String BAR_HORIZONTAL_GROUPED = "bhg";
public static final String BAR_VERTICAL_GROUPED = "bvg";
public static final String BAR_ = "b";
public static final String PIE = "p";
public static final String PIE_3D = "p3";
public static final String PIE_CONCENTRIC = "pc";
public static final String VENN = "v";
public static final String SCATTER = "s";
public static final String RADAR = "r";
public static final String RADAR_SPLINES = "rs";
public static final String MAP = "t";
public static final String GOOGLE_O_METER = "gom";
public static final String QR_CODE = "qr";

您需要做的一切都是为了请求聊天的URL。它会下载作为图像到您的设备。 URL格式如下。

The all you need to do is to request the chat URL. it will download as image to your device. The URL format is given below.

<一个href=\"http://chart.apis.google.com/chart?&cht=p3&chd=t:250,100,40&chs=320x200&chl=Apple|Grapes|Mango\" rel=\"nofollow\">http://chart.apis.google.com/chart?&cht=p3&chd=t:250,100,40&chs=320x200&chl=Apple|Grapes|Mango

CHT =图表类型
CHD =图表数据
CHS =图表大小
CHL =图表标签

cht = chart type chd = chart data chs = chart size chl = chart label

享受。
