- DrawGraph - LINE PLOT - notes
-
- The flag 'FROM_ORIGIN' means different things when
- you try to do different things. It essentially
- adds 'another' data point to be concidered & hence
- plotted into lines etc...
-
- The variable 'POINT_MARKERS', currently has four
- possible values, and some are more suitable than
- others for various data sets because of their
- shape. Technically the best is 'CROSSED_BOX'
- because it marks 'exactly' the position of the
- data pair because it has a 'cross-hair'.
-
- The variable 'LINE_IS_A' defines one of three
- types of lines that the code can draw. The
- LINE_PLOT just draws a line between the points,
- CURVE_FIT does a beziere (sp?) curve around the
- points taking the two control points to be a
- line that extends across the X-axis 1/2 way
- between 'n' and 'n-1' or 'n+1'. The Y-axis
- point follows a line with gradient taken
- from the gradient between (n-1) and (n+1).
- LINE_OF_BEST_FIT just gets an average point,
- and average gradient, and the rest I'm sure is
- 5th form maths!!! :-)
-
- I strongly reccomend that you get your data in
- numerical order on the X-axis in the file.
-
- The LINE_OF_BEST_FIT might be a bit unreliable,
- and so if you get some strange results, or no
- result it's not your fault!!!! :-).
