# Besides what we have seen in (L) and (N1), there are many ways to get simply bar and
# circular charts:

da = c(237.5,137.5,125); co = c("red","yellow","blue")
StripNames = c("A","B","C"); StripC(da,co)           # (1)
BarNames = c("A","B","C"); BarC(da,co)               # (2)
noGrid=1; BarNames = c("A","B","C"); BarC(da,co)     # (3)
PIE2C( da, c("grey50", "grey75", "grey95") )         # (4)
PieC( da, c("grey50", "grey75", "grey95") )          # (5)
PIE_( da, 4 )                                        # (6)
Pie_C( da,co, 27)                                    # (7)
Pie2( da )                                           # (8)
PIE2( da )           # as (8) without grid [as PIE_(da,1)]

# While Pie, PIE, PIEh, Bar, BAR, Strip, PIE_, PIE2 automatically chooses the colors,
# with PieC, PIEC, PIEH, BarC, BARC, StripC you can add colors

# In addition to PIE2C (4), Pie2C automatically adds letters.

# For simplicity, names are automatically assigned to the circular charts. If I have to
# distinguish different charts I can give them different names with commands PIE_C,
# Pie_C, PIE_, Pie_, similar to commands with 2 instead of _, to which I add, after a
# comma, a number that indicates the name of the first sector: letters A, B, ..., Z are
# indicated by numbers 1,2, ..., 26, letters a, b, ..., z by numbers 27,28, ..., 52.

# If you type DimCa <<- n with n < 1 and (instead of BARC and BarC) you use BARCC and
# BarCC, you can write the BarNames with smaller dimension.

# You can also indicate a single color:
BarNames = c("A","B","C"); BarC(da,"yellow")
BarNames = c("A","B","C"); BARC(da,"yellow")
# data:  237.5 137.5 125
#    %:  47.5 27.5 25
