Show selected date and date -1 day on line chart

[#1]

Hi,

I have a line chart that shows the count of all transactions for a given date (selected my picking year/month/day).

The Y axis shows the count and X axis shows the hours of the day that the transactions took place.

I need to now add a second line to the chart with the prior dates data.

I have been looking everywhere with no luck. I am new to Qlik so not sure where to do this, so a setp by step would be nice,

May be like:

=Sum({<Date={"$(=Date(Only(DateField)-1))"} >} Amt)    // for date -1

Do you want to have two lines on your Line chart showing today's data and yesterdays data for hours on  x axis?

Sudeep, no, I have onle 1 line but I would like to add a second one.

Tresesco,  i added COUNT ({<bladate={"$(=Date(Only(bladate)-1))"} >} Folio)  as a second expression and nothing shows.

By the way, the demension of the chart is Hour.

Just as a test I made the second expression

SUM(IF(bladate='02/06/2014',[FOLIO]))

If I change the date for bladate it returns nothing on the chart
