+The returned object contains all the necessary information for data representation (geo-location, time ...). In the next lines we plot the loaded time series for each member. The element `Data` contains the data itself. In this case, it is a 2D array with the dimensions `time` (92 days for June, July and August) and `member` (10 members selected), as indicated by the `dimensions` attribute:
 
 {{{
+> str(ex.point$Data)
+ num [1:92, 1:10] 19.7 24.4 24.4 24.5 26.6 ...
+ - attr(*, "dimensions")= chr [1:2] "time" "member"
 }}}
+
+In the following example we plot the time series with the multi-member mean and its dispersion (interquartilic range 25-75):
+
+{{{
+> quartiles <- apply(ex.point$Data, MARGIN = 1, FUN = quantile, probs = c(.25,.75))
+> ens.mean <- rowMeans(ex.point$Data)
+> dates <- ex.point$Dates$start
+> plot(dates, ens.mean, ylim = range(ex.point$Data), ty = 'n', ylab = "tas - 12UTC", xlab = "time")
+> polygon(x = c(dates, rev(dates)), y = c(quartiles[1, ], rev(quartiles[2, ])), border = "transparent", col = rgb(0,0,1,.4))
+> lines(dates, ens.mean)
+}}}
