You probably have to employ -collapse- to get to the table first. No html

Betreff: st: twoway connect

How can I graph data from a frequency table (rows: age classes; col:
platelet counts under/over a certain cut-off) in order to have a line type
plot (twoway connect). In excel I can make the table from the data set
first, and then I can do the plot from the table. In STATA i do the table,
but I cant succeed in doing the graph starting from the original data set
(each row is an oservation, an individual).
 This is the table whose data I would like to graph:
 age        PLT<150        PLT>150
<18        0.7                 4.23
18-39     4.2                 0.3
40-59     7.69               0.62

=60      11.42             0.28

 May anyone help me?
