Scatter plot - how to create error bars just for the average line.

[Eddie Vo]

Hi all, I am relatively new to Spotfire. I have a data table with a batch column where I have all of my records. I created a line graph measures VCD over time.

 

here is what it looks like

 

I also have data of the median, std -1, std +1 as well in the column. What I am trying to figure out is how do I show just the average with the errors bars coming off it. The values of the error bars are from the standard deviation values in the column.

 

What is the best approach to this I made a mockup in photoshop of what I wanted. Is this possible in Spotfire
