Publishing graph of unpublished work in paper I am writing a paper which is building up on the work I have published earlier. It includes experimental results which were used to further develop the model. 

To show that the model has improved I would like to include a graph of one of my experimental work showing the model predictions before and after the implementation of the improvements. The graph of the data has not been published and will be included in my PhD thesis. I would like to publish that data together with a similar series which I will use to evaluate my model (can can be used to evaluate similar models) in a separate paper. 

Can I use the graph and reference it as my unpublished thesis. I have a thesis title already.

Many Thanks
You can state that " according to the (or based on yet) unpublished data collected in our lab or by xxx .....". It is widely used with no problem. (I am assuming you got permission from your advisor)
