Why do I get values above 1 in ksdensity?

Hi everyone, I've been plotting a ksdensity on a variable distribution, I noticed on the y axis values above 1. Isn't supposed to be a [0-1] probability of occurence of the xaxis value? Thanks

"Unlike a probability, a probability density function can take on values greater than one; for example, the uniform distribution on the interval [0, ½] has probability density f(x) = 2 for 0 ≤ x ≤ ½ and f(x) = 0 elsewhere."

I found out that it actually integrates to 1. Thank Walter for your help.
