draw curve into display

command: CURVE <curve-file>

Draws curve into trace display. The curve is read from file <curve-file>. It uses the coordinate system defined by the time axis and the y-axis. The curve file contains pairs of coordinates (time,y) in each line, which are connected by straight lines in the display. An empty line stops the polygon and starts a new line at the next pair. If a line starts with "TEXT: " the rest of the line is printed at the last read location.

Curve files are searched first in the current directory then in the directory specified by the "SHD_CURVES"-path.


  • <curve-file> parameter type: filename (without extension)
    File which contains curve. It must have the extension ".CRV" and start with a line containing "SH_CRV" at the very beginning. Each line of the file contains either:
    • a coordinate pair "time y" (separated by blanks)
    • nothing
    • an output text (line must start with "TEXT: ") Coordinate pairs are connected until a blank line is read. A blank line starts a new polygon. An output text is printed at the last read location.


  • /neg
    If this qualifier is specified, all y-values are sign-reversed.
  • /clip
    Clips output to section of trace display
