How to add target line in Bar Graph using mschart

Hi! I've been searching for like 2 days on how am I gonna plot a target line in bar graph mschart. I've created a bargraph and it's data coming from database, now I want to set a target line for it but when I tried putting this .seriescolumn = 2 and .chartype=line.... all of the graph becomes line but no plotting happening.
I just want to know if there is a way to plot a horizontal line in my graph and also if there is a possibility to hava datapoint label in every data in my bar graph so it is readable.
