Re: Error checking in scatterplot

[Friedrich Beckmann]

Hi John,

the syntax is

GRAPH

/SCATTERPLOT = x WITH y

see: http://benpfaff.org/~blp/pspp-master/latest/source/user-manual/pspp.html#GRAPH

The code fragment checks the existence of y but at that point of parsing x is already in the

variable array. Therefore n_dep_vars is 2 but „only one variable“ is allowed after the WITH.

Just checking ....

This fragment from src/language/stats/graph.c :

if (graph.scatter_type == ST_BIVARIATE && graph.n_dep_vars != 2)
{
       lex_error (lexer, _("Only one variable is allowed."));
       goto error;
}


The error message does not seem to fit the condition.   Should one or the other be
updated?
