I have a table with the headings Type, Date, Number of Items, and it is
sorted by Type and then by Date. I have made subtotals of the Number of Items
for each Type on each Date. Now, I want to make a stacked-column bar chart
where there is a bar for each date and the colors in the stacked bars are
broken down by Type. I cannot for the life of me figure out how to get Excel
to generate this bar chart just from my subtotals. I actually have MANY of
these to make and thousands of items in each table. Please help me!
