# Permanent Curves

## Click on (G) (F) from the main menu to get this menu

- (F)reeze This freezes the current curve 0 for the current plotting window. It will not be plotted in other windows. If you change the axes from 2 to 3 dimensions and it was frozen as a 2D curve (and vice versa ) then it will also not be plotted. It is better to create another window to work in 3 dimensions so this is avoided. A parameter box pops up that asks you for the color (linetype) as well as the key name and the curve name. The curve name is for easy reference and should be a few characters. The key name is what will be printed on the graph if a key is present.
- (D)elete This gives you a choice of available curves to delete.
- (E)dit This lets you edit a named curve; the key, name, and linetype can be altered.
- (R)emove all This gets rid of all of the frozen curves in the current window.
- (K)ey This turns the key on or off. If you turn it on, then you can position it with the mouse on the graph. The key consists of a line followed by some text describing the line. Only about 15 characters are permitted.
- (B)if.diag will prompt you for a filename and then using the current view, draw the diagram. The file must be of the same format as is produced by the Write pts option in the AUTO menus. The diagram is colored according to whether the points are stable/unstable fixed points or periodics. The diagram is ``frozen'' and there can only be one diagram at a time.
- (C)lr. BD clears out the current bifurcation diagram.
