Well, Unfortunately the documentation hasn't helped me to plot the heatmap in a presentable way. Therefore I posted it here, since I was assuming that other scientist must have run into these problems as well and might have already found a way to solve these issues. I also think that most people here have the ability to read upon material...so it is obvious that I need help and am not only posting to steal time from people. And if people don't feel like helping or answering, then they won't anyway...no matter how you title a question!!!
