The tsEdit Basics

The tsEdit window presents the user with a 2-dimensional graph on which time series data (actually any 2-dimensional data) can be entered and edited.

If tsEdit is started without an initial file, the program uses 3 random points for the initial plot.

The graph consists of two related sets of data points:

"Knots" are the points that control the curve. Knots are indicated by the small circles joined by red lines.
Knots can be Added, Moved and Deleted by the user.

Interpolated points, which are points that are generated by tsEdit according to the rules indicated by the user (See Interpolation Methods). Interpolated points are indicated by the black lines. Interpolated points cannot be edited.

Moving Knots

Knots can be moved by dragging them. When the cursor is over a knot, a vertical broken line appears indicating that the knot can be selected and dragged. The relative position of the knots can not be changed if an interpoated curve is being drawn. In other words, a knot cannot be dragged past another knot.
