Line chart

I am using Kibana 4.5.I am drawing a line chart.I need a threshold line to be added along y axis.I tried using Scripted field but it comes only as dots.When i use USE CONNECTING LINES it connects all dots.But I need the threshold line alone to be connected and remaining plotted points as dots. Is there a way to draw this in line chart
