PLACING A GRADIENT LINE |
||
|
In "Add gradient" mode simply mouse click and use the rubber-band line to best fit the data. Mouse click again to place the line. As the gradient is interactively calculated, a preferred gradient can be searched for among the data points. Once placed the gradient line is easily moved or rotated for a better fit. A least squares fit is also available |

Continue adding gradient lines until the data points are properly interpreted (below). Each gradient line is annotated with its gradient. Gradient units are selectable independently from the data depth and pressure units. Intersections are automatically calculated and plotted. They can be selected and annotated. |
