Slope of the current line.

**getslope** displays the equation of the current line of the figure. Use
the menu 'Insert > Line' to draw a line first. **getslope** allows for
rough curve fitting "by eye". You may also use the shortcut Ctrl+G if
the Ezyfit menu has been installed (see efmenu).
Depending of the axis types, the equation of the line will be:
Y = N*X+A for X linear and Y linear
Y = A*X^N for X log and Y log
Y = A*EXP(N*X) for X linear and Y log
Y = A+N*LOG(X) for X log and Y linear (LOG = natural logarithm)
**getslope**('Property1',...) specifies the display mode:
'figure' output the result in the figure (by default)
'command' output the result in the command window
'nodisplay' no output
'slope' displays only the slope N (by default).
'equation' displays the full equation (e.g., N*X+A)
[N, A] = **getslope**(...) also returns the parameters N and A of the
equation.
