Hi all,
I don't understand very well the principles of oriented
programmation and I have some diffculties with the function addTA().
I suppose I have plotted a time serie with the function candleChart()
for example.
I have a vector y with 1,-1 and 0 values with the same length than my serie.
If i want to add a shaded region corresponding to the value 1, I can do
it with
addTA(y==1,col="gray90",border=NA,on=-1)
So I would like to write a function that add the three different regions
I tried this
addshaded=function(x){
addTA(x==1,col="gray90",border=NA,on=-1)
addTA(x==-1,col="green",border=NA,on=-1)
addTA(x==0,col="red",border=NA,on=-1)
}
But the command addshaded(y) does not add the three different
shaded regions. ;-(
Regards,
Olivier.
