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. Mac
