描述
disp_arrowdisp_arrowDispArrowDispArrowDispArrowdisp_arrow displays one or several arrows in the output
window. An arrow is described by the coordinates of the start
(Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1) and the end
(Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2). An arrowhead is displayed at the end
of the arrow. The size of the arrowhead is specified by the parameter
SizeSizeSizeSizesizesize. If the arrow consists of just one point (start = end)
nothing is displayed. The operators used to control the display of regions
(e.g., set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_colorset_colorSetColorSetColorSetColorset_color,
set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidthset_line_width) can also be used with arrows. Several arrows
can be displayed with one call by using tuple parameters. For the use of
colors with several arcs, see set_colorset_colorSetColorSetColorSetColorset_color。
注意
The start and the end of the arrows must fall within the window.
