View

Set the display of the status bar, tool bar, locator bar, and properties associated with the display of the pointer position in the Locator bar.

Status bar
Toggle the visibility of the Status bar that appears at the bottom of the display.
Tool bar
Toggle the visibility of the Tool bar at the left of the display.
Locator bar
Toggle the visibility of the Locator bar, at the top of the display.
Set fixed point
Select this item, then click on the drawing area to set the posistion of the fixed point. To set the position more precisely, use the Locator props popup described below. When the fixed point is set, and the display format is (DX, DY), (DIST), or (R, Theta) then give the location relative to the fixed point.
Clear fixed point
Set the fixed point to (0.0, 0.0).
Locator props

Set properties associated with the display of the pointer position in the locator bar.

The choice item at the top of the popup, Locator: ON/OFF toggles the continuous update of the pointer as it moves across the drawing area. Locator display type is a choice item the sets the display of the position. There are several options:

[X,Y] The default, display the position in the coordinate system of the current graph.
[DX, DY] Display the delta in X and Y of the position of the mouse relative to the fixed point, or (0, 0) if no fixed point has been selected. The position is given relative to the scaling of the current graph. DX = (CX - FX) and DY = (CY - FY).
[Distance] Display the position of the mouse as the distance from the fixed point, or (0, 0) if no fixed point has been selected. The distance is computed as SQRT((FX - CX)^2 + (FY - CY)^2) where (FX, FY) are the coordinates of the fixed point, and (CX, CY) is the posisiotn of the pointer.
[R, Theta] Display the position of the mouse in polar coordinates (R, Theta) relative to the fixed point, or (0, 0) if no fixed point has been selected. R = SQRT((FX - CX)^2 + (FY - CY)^2) and Theta = ATAN2(DY, DX).
[VX, VY] Display the position of the mouse in viewport coordinates. This position is independant of the scaling of the current graph.
[SX, SY] Display the position of the mouse in screen coordinates. This position is independant of the scaling of the current graph.

The next two categories in the popup set the format and fixed point positions for each coordinate direction and, as they are identical, only setting the format and position of X is described here. The description for Y is identical save that ordinate is replaced by abscissa.

Format X: is a choice item selecting the format of the display of the X position of the pointer. There are several selections here:

Decimal
Exponential
Power (displayed as Decimal)
General
DD-MM-YY
MM-DD-YY
MM-YY
MM-DD
Month-DD
DD-Month
Month (abrev.)
Month
Day of week (abrev.)
Day of week
Day of year
HH:MM:SS.s
MM-DD HH:MM:SS.s
MM-DD-YY HH:MM:SS.s
Degrees (lon)
DD MM' (lon)
DD MM' SS.s (lon)
MM' SS.s (lon)
Degrees (lat)
DD MM' (lat)
DD MM' SS.s (lat)
MM' SS.s (lat)

The Date format requires that the axis be scaled with respect to the long form of the Julian date. The Degrees format is for latitude and longitude. Below the equator latitudes are negative. Longitude is assumed positive east of Greenwich and negative to the west.

Precision X: sets the number of places to display to the right of the decimal point.

Fixed point X: defines the position of the ordinate of the Locator fixed point.

If everything looks OK, click on Accept to register the selections, Reset to restore the startup values, and Close to close the popup.
