Hi Eva,
Your code should look something like:
DEFINE FILE XYZ
LINE/I9=90;
END
GRAPH FILE XYZ
SUM MON TUE WED THU MAX.LINE
ACROSS PERCENTFIELD
END
then you can use the standard graph functions to set LINE to a line, (if the others are bars), remove the line markers, change the colour and change the width by using the java applets. If you don't know how to make these changes, I can look it up.
