We trace signatures of quantum chaos in the distribution of nodal points and streamlines for coherent electron transport through different types of quantum dots (chaotical and regular). We have calculated normalized distribution functions for the nearest distances between nodal points and found that this distribution may be used as a new signature of quantum chaos for electron transport in open systems. All irregular billiards shows the same characteristic distribution function. These signatures of quantum chaos are well reproduced using well-known approaches of chaotic wave functions with the same characteristic distribution function. We have also investigated the quantum flows and have found some remarkable properties of them.
