Scatter plot - lines and curves - line width depending on column value

[Spencer Alexander]

Hello,

I am trying to add a horizontal line (curve from data table would also work) on a scatter plot, with y-value equal tothe average value of a variable. I also want to have a shaded region around around that line, corresponding to the standard deviation of the variable.

One way I can think to do this is to plot both of two horizontal lines:

1. The horizontal line with the average y-value (currently populated through a column of a data table, 'var_avg'),a small line width, and a solid color.

2. The horizontal line with the average y-value (currently populated through a column of a data table, 'var_avg'), a line width corresponding to the standard deviation (this I could populate as e.g., another column in the data table, 'var_std'), and a transluscent color.

However, I do not know how to make a line width that depends on a column value. Is there a way that I can do this

Alternatively, is there another entirely different way that I could accomplish my goal

Thanks.

Set up a Document Property that calculates the average value of your column, then set the line value equal to the Document Property value.
