This plugin lets you set your blog goals and monitor them. The goals are displayed in the form of Google Gauges
For each chart, the main configuration piece is set by the options field width: 200 , height: 200 , min:0 , max:10 , redFrom: 0 , redTo: 1 , yellowFrom:1 , yellowTo: 4 , greenFrom:4 , greenTo:10
Let say you are tracking the comments on each post. You have got a good readership and on an average you get around 5 comments/post Now your goal is to increase the average comments/post. So you can set the following options
width: 200 , height: 200 , min:0 , max:25 , redFrom: 0 , redTo: 4 , yellowFrom:4 , yellowTo: 10 , greenFrom:10 , greenTo:25
min:0 and max:25 sets the dial's range redFrom:0 to redTo:4 => If the average comments drop below 4 then the pointer will be in the red zone yellowFrom:4 to yellowTo:10 => If the average comments is between 4 and 10 then it is ok so in the yellow zone greenFrom:10 to greenTo:25 => If the average comments goes above 10 then you have met your goals and hence in the green zone
NOTE: We are using Google's Visualization API to display the Gauges. If you want to change the size of the Gauge then try changing the height instead of the width. The width parameter is not as influential as the height parameter.
