I want to extend data in an already established Excel spreadsheet and wonder if anyone can help. I weigh myself every day and have a spreadsheet with monthly columns where I add my weight for each day, and from this data, I got Excel to create a line graph to show my weight fluctuations over several months. Because there is a different color for each month, it's a very effective to see the "ups and downs" of the changes in my weight. The spreadsheet/graph only goes until the end of June and I would like to extend it at least until the end of December. When I first created the spreadsheet/graph, I designated the months that I wanted to include (Sept to June) but now realize this is inadequate. I tried simply moving the graph over and adding more months to the existing month columns, but it didn't work. I would appreciate any and all help! TY.
