You are trying to make a chart that is both grouped and stacked - the two expressions side by side require a grouped chart, while the Line of Business require a stacked chart. This is not something you can implement in QlikView.
Even if it was possible, the visual effect would be really hard to process - you'd need to follow monthly trend, through comparing year by year and divided by Line of Business... Too complex...
You'll need to reduce the complexity by one dimension - either show a stacked chart of monthly trends by Line of Business, or show a grouped chart of Monthly Trends comparing Year over Year, but without the distribution by Line of Business.
You can convert the field name of the sales fields into a dimension, using Crosstable
Crosstable(Year, Sales, 2)
LOAD * INLINE [
Incurred Month, Line of Business, 2013 Sales Per Member, 2012 Sales Per Member
Apr, Electronics, 2.19, 2.51
Jan, Electronics, 2.76, 2.53
Mar, Electronics, 2.94, 3.45
Feb, Electronics, 3.45, 3.15
Feb, Furniture, 9.92, 12.13
Mar, Furniture, 10.09, 12.65
Apr, Furniture, 10.59, 12.41
Jan, Furniture, 12.77, 12.31
Feb, Kitchen, 57.48, 63.01
Mar, Kitchen, 59.01, 67.60
Apr, Kitchen, 60.88, 58.68
Jan, Kitchen, 64.69, 66.18
Thus will result a table containing Month, Line of Business, Year and Sales.
Afterwards you can create a bar chart, having month and LoB as dimensions, sum(sales) as expression, and, of course, Stacked option selected within the Chart's Properties >> Style.
