Here we explore the Graph Layer options:
Image Underlay

Once in image underlay editing mode, select Add to pick and define the graph image which will assist in the creation of Overlay and Underlay objects on a graph.

Drag the red square anchor points to the corner extents of the graph to define the shaded region that will be imported. Ensure the values in the minimum and maximum X & Y cells match the values on the import graph axis corresponding with the corners of the shaded region. Select Import to image underlay and once in click Done.

An image underlay can be use in scatter plots, tri-plotsdepth plots & single-track multi-depth plots.

Re-enter the Image Underlay Editor, select image and hit delete once finished creating/editing the over/underlay layer items. Hit Done to exit.

Over / Underlays

Enter the Overlay or Underlay Editor and resize the screen to clearly see the graph. A selection of drawing objects is available to use in order to create interpretative zones on the graph.

Once created, resize using the corner blue square anchors and reposition the entire object using the central red square anchor.

With the drawing object created and selected there are a host of object edit items, listed on the left hand side of the edit window, such as fill / line colour, line width etc.

There is also an option to provide a Legend label (appears when Show in Legend is selected from the top of edit layer options and the Legend is displayed from the Graph Manager Layout tab properties list)
