Chart Development and Application of Google API

Today, I want to make a Statistical Chart and look at the Google API documentation. I just made a small example.

 

You only need to add an IMG label locally to add the URL Connection with parameters. Google will automatically generate a PNG chart image for you.

Http://chart.apis.google.com/chart? This is required, followed by the style and title of the desired chart. The parameters are not described in detail, because Google's API documentation has already been explained in great detail. The following describes the API documentation address.

 

Note that Google generally only allows a maximum of 10000 calls per day. If this number is exceeded, you have to contact it. I think we should pay for it.
