2 data points on a chart

Hi guys would appreciate any help,

I am constructing a line chart and one of my data series has 2 values which fall in the same part on the x-axis.

one of my x labels is '95%' and there are two values which fall in this value, so i need two points. One is a higher value on the y axis so it will create a straight line.

How do i do this on excel???


Many thanks

James
