Then that is your takeaway. There is absolutely no need to use so much text and color. Choose a few key categories that are a good representation of people's overall shopping habits and add those as your colored lines. You can add another line with a neutral color combining all the rest and show the average values over time. Drop all the numbers from the chart and add a subtitle that says how nothing has changed despite this and that. And please use a logical order for the dates on the X axis.
