How can I assign a fill to a specific value in Grapher?

To fill a plot only to a specific data value in Grapher:
 
  1. Create a line plot by clicking the Home | New Graph | Basic | Line Plot command.
  2. Select your data file and click Open. For example, I am using tutorial.dat, located in the Grapher Samples directory. The graph is created.

  1. Click on the Line/Scatter Plot 1 in the Object Manager to select it.
  2. In the Property Manager, click the Fill tab.
  3. Change the Pattern from None to Solid.
  4. Set the Foreground color as desired.
  5. Change the Direction, if desired.
  6. Change the Cutoff value by highlighting the existing value and typing a new value. For instance, if I want the graph to be filled down from the line to the value Y=55, I would type 55 for the Cutoff.
  7. To change the background color:
    1. Click on Graph 1 in the Object Manager to select it.
    2. In the Property Manager, click the Fill tab.
    3. Change the Background color and Opacity as desired.

 

The fill updates to show the fill only the portion of the graph that fits the Direction and Cutoff.

The graph shows the fill from the plot to the cutoff value.
