How to add a vertical reference line, and changing line type in Qliksense

[Anonymous]

Hi,

anyone could give a suggestion, using a line chart for following 2 tasks?

I have my X-axis using date from 2017-10-01 to 2017-10-31, Y-Axis as Sales

1. I want to add a vertical line at 2017-10-07 . as the 'current date'

How can I add it? i was using appearance, reference line but seems that only response for the horizontal line.  can not add a vertical line

2. I have 2 lines one called 'real line' the other called 'prediction' (both line have 30 data points along the timeline)

How could I change the 'prediction line' to dashline?

Thank you!
