Description

disp_arrowdisp_arrowDispArrowDispArrowDispArrow displays one or several arrows in the output window. An arrow is described by the coordinates of the start (Row1Row1Row1Row1row1,Column1Column1Column1Column1column1) and the end (Row2Row2Row2Row2row2,Column2Column2Column2Column2column2). An arrowhead is displayed at the end of the arrow. The size of the arrowhead is specified by the parameter SizeSizeSizeSizesize. 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_drawSetDrawSetDrawSetDraw, set_colorset_colorSetColorSetColorSetColor, set_line_widthset_line_widthSetLineWidthSetLineWidthSetLineWidth) 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_colorSetColorSetColorSetColor.

Attention

The start and the end of the arrows must fall within the window.
