Numbers chart
I need help creating a 3-line chart in Numbers. I have 3 kids, Sam, age 13, Frank, age10, and Adam, age 6. I want to record their individual gains showing their weights at monthly intervals on a single chart. I entered the data in Excel with 24 months across the top and weights ranging from 50 to 250 in increments of 10. up the left vertical axis. But I don't know how to plot a red line for Sam, a blue line for Frank, and a green line for Adam. Please tell me how.
