We'll create fresh WordPress site with Simple Graph installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Draws a graph of single set of date related data. Graph can be made public (i.e. sidebar widget or static page) and the data can be manipulated through dashboard. Many people use this plugin for weight tracking on their blogs (as do I), but it has been used for many other things as well. Only requirement – or rather a constraint – is that the horizontal axis of the graph shows dates. The vertical axis can hold any values. Each user can have their own graphs, which can be easily inserted in posts and pages.
If you want to insert a graph in posts and/or pages, simply write a string similar to following in your post or page.
[[simple-graph n=1 x=0 y=0 trend=0 wkly=0 lm=0 ytd=0 uid=0 gid=0 ]]
Just replace the values as you wish. The ones above are default values, and if you don’t need to change the default value, you can simply omit that value from the string. I.e. [[simple-graph]] alone produces the graph with default values drawn from widget setup.
