I need to output an ASCII file to a waveform graph.

[adomon79]

The output ASCII file looks something like this:
SP1;PU;PA687,1402;PU;PA687,1402;PD;PA687,4282;PD;PA687,7162;PU;PA1625,7162;PD;PA1625,4282;PD;PA1625,1402;PU;PA2562,1402;PD;PA2562,4282;PD;PA2562,7162;PU;PA3500,7162;PD;PA3500,4282;PD;PA3500,1402;PU;PA4437,1402;PD;PA4437,4282;PD;PA4437,7162;PU;PA5375,7162;PD;PA5375,4282;PD;PA5375,1402;PU;PA6312,1402;PD;PA6312,4282;PD;PA6312,7162;PU;PA7250,7162;PD;PA7250,4282;PD;PA7250,1402;PU;PA8187,1402;PD;PA8187,4282;PD;PA8187,7162;PU;PA9125,7162;PD;PA9125,4282;PD;PA9125,1402;PU;PA10062,1402;PD;PA10062,4282;PD;PA10062,7162;PU;PA10062,7162;PD;PA5375,7162;PD;PA687,7162;PU;PA687,6586;PD;PA5375,6586;PD;PA10062,6586;PU;PA10062,6010;PD;PA5375,6010;PD;PA687,6010;PU;PA687,5434;PD;PA5375,5434
;PD;PA10062,5434;PU;PA10062,4858;PD;PA5375,4858;PD;PA687,4858;PU;PA687,4282;PD;PA5375,4282;PD;PA10062,4282;PU;PA10062,3706;PD;PA5375,3706;PD;PA687,3706;PU;PA687,3130;PD;PA5375,3130;PD;PA10062,3130;PU;PA10062,2554;PD;PA5375,2554;PD;PA687,2554;PU;PA687,1978;PD;PA5375,1978;PD;PA10062,1978;PU;PA10062,1402;PD;PA5375,1402;PD;PA6

Any suggestions?

I don't understand the question. What are the numbers that you are wanting to plot in the ASCII file? What is the source of the ASCII file? What is the format of the data in the data file? Is it in an x,y format or a vector coordinate format? With a little more information I expect that this will be rather easy.

Thanks for your help. The questions that you asked helped me dig in a little deeper. It turns out that the format is HPGL (Hewlett-Packard Graphics Language). It's basically a file type that can be read in Word.

Thanks again!

That's HPGL, a language used for plotters.

Think in those terms and you can do it.

You need an X-Y graph, not a waveform graph.

split the text at the semicolons first - they delimit a single command.

The first two characters of a command string are the command, the rest are the data for that command:

SP means select pen (choose color)

PU means pen up (don't draw a line to the next coordinate).

PD means pen down (do draw a line to the next coordinate).

PA gives an X-Y coordinate to move the pen to. That will / won't draw a line, depending on whether the pen is currently down or up.

That should get you going.

Thanks for the help!!!

Hello

Take a look at this link. They have an "hpgl plotter" converter that can be useful.

Hope this helps.
