Image 41 - An example of using the parse tree generator on an Excel Formula.
Here the formula "=1+2/3*4+SUM(A1:B2,1*1)
" is first tokenised and then converted to a parse tree. The result
is displayed as a JTree for faster programming.
At one stage the parse tree generator was having difficulties distinguishing between negative and minus (as they both use the same symbol). I believe this has now been corrected.
Other sample parse trees 1 2.
Image 42 - Row and column occupancy thatching.
Here a darker shade of blue is choosen for each row or column if it has a higher occupancy level.
This visualisation should be more interesting when combined with other metrics.
Using same worksheet as Image 16.
