changing x-axis on charts

hey guys, im new to creating reports. im hoping someone can help me. im trying to create a report with charts. heres what my situation is:
i have a table with the responses to a survey. when the survey results are inserted to the table, i only enter the codes, not the strings (ie. ans1 = 0 or 1)
the problem is when i create my table, my x axis labels only display the number (because thats what i saved). ive tried opening the tables data sheet and changing the lables there. it changes it in design view but not in print preview view. any suggestions?

this is for an access report 2003
