Usage

addSingleValue(ColMap, s1 = 0.05, s2 = 0.001)

a named numeric vector,e.g. c('yellow'=0,'red'=8.99,'green4*'=9)

s1, s2

portion of the whole legend; they are used to control the width of the color band for the specific value; for example

• c('yellow'=0,'red'=8.95,'green4*'=9), the width is 8.95*(1+s2) to 9

• c('yellow*'=0,'red'=0.05,'green4'=9), the width is 0 to 0.05*(1-s2)

• c('yellow'=0,'red*'=1,'green4'=9), the width is 1*(1-s1) to 1*(1+s1)
