I want to plot something with doulble x ticks labels one for the item name and other for the purchase month
Month | Item | Price |
---|---|---|
Feb | Tomatoe | 15 |
Feb | Cockies | 10 |
Feb | Juice | 20 |
Feb | Orange | 13 |
Mar | Cake | 11 |
Mar | Potato | 30 |
Mar | Juice | 13 |
I tried using twiny() but I want the labels on the same side. Excel Pivot Chart does the work but the performance is very low with huge amount of data.
