Help Text: ' This Help topic will provide information on how to format textfiles so that FzzPlot can read them and generate plots. The FzzPlot Tutorial (supplied with your copy of FzzPlot, hopefully!) gives a very detailed description of the process of creating a datafile, for novice users of the Macintosh. In the Tutorial, you will find many pictures to help.
FzzPlot expects the textfiles you feed it to be in an orderly format; the values for a single data point should all be one a single line, and there should be only one data point per line. For example, a single point might look like this:
2.0 4.0
The first number (2.0) is the horizontal coordinate, and the second number (4.0) is the vertical coordinate. If you are plotting data with error values, a single data point would look like this:
2.0 4.0 0.34
2.0 is the horizontal coordinate, 4.0 is the vertical coordinate, and 0.34 is the error value. Something to watch for: all of the data points in a file should have the same number of values. For example, FzzPlot will not read the following data points:
1.0 2.0 0.23
1.1 3.0
1.2 3.4 0.10
FzzPlot reads the first line, sees three values, and therefore expects that ALL lines in the file will have three values on them (horizontal and vertical coordinates, and the error value). Likewise, the following is incorrect:
1.0 2.0
1.1 3.0 0.43
2.0 3.3
Again, FzzPlot sees two values on the first line, and therefore requires that all lines in the file have only two values on them.
Also, FzzPlot expects that numbers be formatted according to this simple rule: if there's a decimal point, there must be at least one digit on each side of the decmal point. Thus, the following numbers are correct:
-4.0 (a zero on the right side)
+0.1 (a zero on the left side)
104.5 (digits on both sides)
-58 (an integer)
The following numbers are incorrect:
4. (needs a zero on the right side)
.453 (needs a zero on the left side)
Note that you can have a sign in front of a number, if necessary.'
