Fix a value in line chart so that it will not change with Dimension changes

[#1]

Hello everyone：

     I meet a problem when designing a line chart with one dimension and two expressions.

     The dimension is Date.

      Expression1 is  required to show value  fixed to one of Date and never change with Date change.

      Expression2 is required to show values change with Date change.

      Here is  sample data:
      Date  Value

      1          1

      2          2

      3          3

      4           4

      5            5

     The line chart  I want is in the attachment.

     Thanks for reading. I am really confused about it.

      Anyone with good solution?
