Attached is the workbook that I need help with. In the sheet named "Graphs - Ivory" I created 4 graphs using the data on ivory in the sheet named "Data." These 4 graphs (for my L readings, a readings, b readings, and DE readings) came out right. However, when I try to make a graph containing all of the data, the lines I get on my graph are wrong. If someone could make me a graph that displays the L readings, a readings, b readings, and DE readings accurately, it would be appreciated.
