Dear Frieder,
one more comment.
Instead of using "foo"-data, it might be more useful to plot each graph
several times.
Otherwise the y-axes are not assosiated with the data and you have to take
more care about them.
e.g.:
// display all graph on first x-axis
plot2d(x1,y1); // and hide the y1-axis
plot2d(x1,y2); // and hide the y2-axis
plot2d(x1,y3); // and hide the y3-axis
// plot the y-axis assosiated with the corresponding data
plot2d(x1,y1); // and hide the graph and the x1-axis and shift y1 to
desired locaion
plot2d(x1,y2); // and hide the graph and the x1-axis and shift y2 to
desired locaion
plot2d(x1,y3); // and hide the graph and the x1-axis and shift y3 to
desired locaion
// plot the x2-axis assosiated with the corresponding data
plot2d(x2,y1); // and hide the graph and the y1-axis and shift x2 to
desired locaion
best regards,
Philipp

In Kanada is' ka' na' da. Sonst wär' Kanada Jemanda.
There we have the salad.
