In order to properly convey the accuracy of your data measurements, Grapher allows you to add error bars to your plots. To better visualize the error envelope that encompasses the error bars, you can connect the error bars with a line, and you can fill between them. This will show your stakeholders that there is nothing to hide, and let your data speak for itself. 

1. Select your line plot.
2. On the Error Bars page in the Property Manager, set the desired Direction of your error bars, and then set the type of error bar.
3. Once your error bars are displaying, check the box next to Connect points. 
4. On the Line page, expand the appropriate "Connection Line" section in the Error Bar Line Properties section, and edit the line properties.
5. On the Fill page, expand the appropriate "Connection Fill" section, and edit the fill properties.
