When I draw a graph on my 9860 it is obsured by a “Syntax Error” message.

Problem: When graphing using my 9860, a “Syntax Error” appears as soon as the graph is drawn.

Likely Solution: There is a syntax error with a function that may not immediately visible in GRAPH mode’s display.

The 9860’s GRAPH mode displays four to five functions, but contains up to twenty functions. You can arrow down to see all twenty. These functions are graphed in order, meaning that if a later function contains a Syntax Error, the error message will block the graphs previously drawn. To resolve this, arrow down and delete or edit the offending function.
