Moves the point to a new location.
move_point( [ChipsId,] xval, yval [,mode])
- ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
- xval - new x location or the difference to move in x
- yval - new y location or the difference to move in y
- mode - reposition using absolute (0) or delta (1) values
The move_point command moves the point to a new position. The new location may be specified as an absolute position (default) or as relative offsets from the original location.
The following coordinate systems may be used to move a point: PIXEL, WINDOW_NORM, FRAME_NORM, PLOT_NORM, or DATA. The system is specified by setting the coord_sys field of the optional ChipsId structure which may be passed into the move_point routine. If a ChipsId is not provided, the default coordinate system of the point is used.
When a point is moved, it remains in its original coordinate system regardless of what coordinate system was used for the move. The move command translates the specified values to the coordinate system that the point is in before applying them to the point. This means that points that are originally placed in normalized coordinates and get relocated using data coordinates will not be clipped if they land outside the visible data range. Conversely, points in data coordinates which are moved using normalized coordinates to beyond the plot area will be clipped.
This command is equivalent to calling the move command with 'chips_point' specified as the object.
Move the current point to the center of the frame in frame normalized coordinates.
chips> id=ChipsId() chips> id.coord_sys=PIXEL chips> move_point(id,-20,0,1)
For a point specified in data coordinates, adjust the position by 20 pixels to the left in the x direction. Do not move it in the y direction.
chips> id=ChipsId() chips> id.point='all' chips> id.coord_sys=DATA chips> move_point(id,40,10,1)
Shift all points by the same distance in data coordinates.
