The interactive trolling curve graph is shown in several places in the Trolling Angles app: The Calibration screen, the Trolling Screen, and the Gauge Setup screen.

The Trolling Angles graph shows the lure at 0,0, the water surface is shown as y feet above the lure, and the x axis shows horizontal distance, not the line length. Line Length is shown along the arc of the line’s curve.

The potential line curve for the rig is shown as a gray line. This line does not change as the depth slider is moved. Trolling Angles is premised on the fact that the submerged line geometry does not change as the line is deployed deeper.

The blue water surface line changes, as you change the depth control slider.

The submerged line, depending on the line length and depth, is shown as red.

The unsubmerged line from the rod tip to the water surface is shown as a straight magenta line.

If the active calibration is part of a Gauge, the other calibrations of the gauge are shown as green curves.

The Graph is designed to give you an intuitive unbiased understanding of line curve geometry and of the capability of the rig. It allows you to best visualize the actual shape of the whole line as you are trolling.

It is not intended to let you use it like a static chart to directly find depth versus length. The numerical information of the Depth Control does that, as the slider is moved interactively.
