How to see all Data Types in Performance Chart after training a network in nntraintool

Hello everyone,
I've just trained a Network on a Data set, but I'm not able to see all three Data types in there. It shows just one curve labeled for test data and a green circle(for validation?!), shown in the Picture below (however the convergence behavior seems to be for Train data, I guess).
I've checked the way I've set up the Data and its form for the network. but it's OK. I've run the samples in Deep learning toolbox documentation( Cancer Detection, Wine Classification and Crab Classification). They've performed well, as written in Documentation, and all three curves were shown. I can't detect what's wrong in my case.
Thanks for your help!

The missing lines are "underneath" the red line. The red line was drawn last, so it is on top.
If you look carefully at the corner near epoch 5 and MSE .6 or so, you can see a place where the green is showing through where the match was not identical. See also from about 525 to 600 the green shows slightly. The blue is underneath the red, it appears to me.
If you zoom in you can probably separate the green from the red better.

This is a common result for good designs.
One hidden layer is sufficient for any problem.
Minimize the number of hidden nodes to mitigate overtraining an overfit net
Hope this helps.
THANK YOU FOR FORMALLY ACCEPTING MY ANSWER
