How to use image-map zoom functions
The plots produced here all contain areas which are "clickable". The
figure below illustrates where the sensitive areas are located and the
functions they serve.
A couple of caveats:
- For this to work your browser has to support so-called client-side
image maps. Server-side image maps can't be used since the areas
covered vary for the different plots and over time.
- If the underlying scripts don't think there is data available for
the "next" and "previous" periods, those areas will not be sensitive.
- The algorithm used for splitting up the X-axis in the plot into
sensitive regions is rather simple-minded, in that it distributes the
X axis evenly between the "zoom-in" references. In cases where only
parts of a week is visible (e.g. when you view a plot of the current
month), the week boundaries will not fall on the Sunday/Monday border
in the plot itself.
