Hi Suneel
You can create measures with the same value in Y axis, and two or more points to cover all the X axis dimension (month/year in the sample).
Then, you can manipulate the lines to remove the markers in the upper/lower limit lines.
I've posted how to do it in these threads:
sap.viz.ui5.Line Control Limits and Marker
sap.viz - scatter + line combination
