## Display distance between 2 lines chart as a third line

hi PBI guru,

I would like to seek help. I have daily sales data of 2 products. I want to display the daily sale of each product and also the sales difference between them in the same line chart. Anyone has an idea how do to it? Thank you so much!

If you'd like to show 2 products on a line chart at one time, you could add "product name" column into slicer, then select two products each time.

Or you could create tables and add columns to slicer.

``````product slicer1 = VALUES('Table'[product])

product slicer2 = VALUES('Table'[product])

Measure = CALCULATE(SUM('Table'[price]),FILTER('Table','Table'[product]=[Selected1]||'Table'[product]=[Selected2]))``````

Do you need to add another line to this line chart which shows the difference of price between two products?

Based on my experience, if you add columns to "legend" field of a line chart,

it is impossible to add more than one measure/column into "Values" field,

thus the line numbers showing one the visual are detemined by the legend.

hi Maggie @v-juanli-msft

Thanks for your detailed guiande. Yes i need to add the price-difference line and i understand the limitation you were talking about. But this output is good enough, so i'll just go ahead with this for now. Thank you 🙂

For a difference you have to create a measure filtering each one of them

calculate(Avergae(table[price]),table[product]="BABA") -calculate(Avergae(table[price]),table[product]="JD")

hi @amitchandak ,

Thanks for your reply. If i have hundreds of product (but I only compare 2 of a time) - is there a more efficient way than listing each of the product and calculate the average for each of them? Thanks!

Assume you are selecting both in one slicer

``````Measure =
var _min = minx(Product,Product[Name])
var _max = maxx(Product,Product[Name])
return
calculate(Avergae(table[price]),Product[Name]=_min) -calculate(Avergae(table[price]),Product[Name]=_max)``````

Or

``````Measure =
var _min = minx(Product,Product[Name])
var _max = maxx(Product,Product[Name])
return
calculate(Avergae(table[price]),filter(all(Product),Product[Name]=_min)) -calculate(Avergae(table[price]),filter(all(Product),Product[Name]=_max))``````

The product is the dimension table for the product. If you do not have one create, otherwise this kind calculation will bring challenges with other filters.

if you need more help make me @
