Statistical visualisation of data has improved dramatically in v 8.0
and provide a very useful way of summarising statistical uncertainty
in measurements or simulations. I've been particularly impressed with
the types of graphs that can be produced using the BoxWhiskerChart[]
or DistributionChart[] functions.
Unfortunately I've been frustrated with the lack of support of these
functions for typical plots of time series or variables which have
either a numerical or date X-axis. Imagine for instance that you would
like to plot the distribution of temperatures within a 24 period and
plot these either in terms of date and/or day of the year, and going
further compare these to another time series of measurements. It is
not possible to specify an X-coordinate for each BoxWisker or
DistributionChart.
In short, what I would like to achieve is something like this
data = Table[RandomReal[ExponentialDistribution[1], 10], {10}];
DistributionChart[data, ChartStyle -> 47,
ChartElementFunction -> "PointDensity"]
with an X-axis which is either a number (e.g. day of the year) or even
better a date. I would anticipate that this can be achieved either
playing around with the ChartLabel[] function or (more generally)
using the PlotMarker[] functionality as this would allow the
superposition of several time series, but I've made little progress
here.
Your help would be much appreciated.
