Copper Kettle Roastery Weekly Sales

Copper Kettle Roastery uses this line graph to compare the sales patterns of its café, packaged beans and catering work. Each line has the same weekly time scale and currency unit, so the owner can see whether a change is isolated to one channel or shared across the business. Catering is more uneven because event orders arrive in bursts, while café sales rise more steadily. That distinction helps when planning production and staffing. The graph shows revenue, not profit; food costs and labour should be examined separately before changing prices or schedules. Use actual settlement dates and consistent sales definitions in a working report. For a longer history, keep the same frequency and avoid adding too many series to one small chart.
