I want to make a graph of monthly Market Share. I want the previous year to be a bar chart, and the current year to be a line graph, and have them overlayed on top of each other...this way I can easily see the year over year change in market share. Columns are months, row is the Market Share %. If possible, I would also like to have different bars/lines for each product category...but it isn't necessary. How can I accomplish this? Thank you!
