Could you please add in the following feature in Calc as it is sorely needed to
make it a more functional spreadsheet program.

When plotting a graph from cell data in Calc there is no option to add custom
values for error bars. Only constant "blanket" values for the whole data series.
The standard deviation option is not much help either as it calculates the
values based on the whole data series, which isn't useful when trying to plot
certain types of data.

Please add in an option were custom values, either for the data series or each
datum, can be added in by refering to a range of cells containg the custom
values. Could you also allow the positive & negative values to be set individually?

I have set this as P1 because it is a vital feature for anyone who regularly has
to compile data sets graphical which involves any kind of statisitics, which
alot of people do. It's one of those features that stops me from using
OpenOffice.org more than occasionally and has been available in many other
office suites for years.
