This is an example of a plot of the GA (google analytics) data stored in Json format. The data is plotted using d3.js. Have a look at the gallery. I do not think I have done d3js justice with my line charts.
Using data from google analytics (GA) (see other posts) a Fast Fourier Transform is performed on the time series data. The absolute value is saved for plotting using d3.js
This post briefly covers connecting to Google Anayltics with a service account (Google Api Console).
In order to connect to a Google Analytic (GA) profile, the following are needed
Sample PHP code to get the number of visitors to a site (profile ID)
Once the GA client is set-up then the following code will return hourly GA data for the given profile.
The slides for the talk describe using PHP to access Google Analytics and present it in d3.js
I am going to cover
I’m doing a talk at Big Data Brighton on April 25th. I will add the slides after but for now I’ll put up the matlab m file scripts. All at: https://github.com/espeecat/big-data-brighton-april-2013
This shows a single sinusoid and Fourier Transform
This is the example which takes several sinusoids, sums them and shows their Fourier Transforms
This is the filtering example
