Vvidget ServerExamples ► System Graphs

System graphs are non-keyed graphs that are used for system related information as well as backwards compatibility with older string input encoding styles. They are of little value for general programming.

An example of a system graph is this URL:

https://www.vvidget.com/graph.pvs?1&EMAIL&pie&2&200,200&1.0,9.0,3.0,8.0,5.0,16.0

which makes this pie chart:

The data is the sequence of values 1.0,9.0,3.0,8.0,5.0,16.0. You can change those values as you wish. You can also make bar charts using this type of URL:

https://www.vvidget.com/graph.pvs?1&EMAIL&column&2&400,300&Bar%20Chart&Bar%20Number&Bar%20Value&1.0,9.0,3.0,8.0,5.0,16.0

Print versions of the graphs can be made by changing the first "2" to "1005 like this:

https://www.vvidget.com/graph.pvs?1&EMAIL&column&1005&400,300&Bar%20Chart&Bar%20Number&Bar%20Value&1.0,9.0,3.0,8.0,5.0,16.0

Click this link: Print Version to make the print version of the graph.

You can also make area and line charts. For instance:

An explanation of this chart making functionality is available in the various sections of this chapter.

If you incorporate this functionality into your web site remember to change the "localhost" part of the URL to the address of your own computer (for example, the address of the VVI web server is www.vvi.com).
