learning_curves chart does not display properly

The charts for each model are blank.
See attached. Thanks

It was only 1 iteration, that's why there is no line in the chart. Please run model with a longer time limit.

For learners with 1 iteration I will plot the bar plot. It will be useful for learners which have only 1 iteration, for example Decision Tree or Logistic Regression.

Ah! makes sense. I just had trouble imagining that 1 iteration would take 1200 seconds. Brings me to another point - is there a way we could provide a verbose ++ advanced mode where we could see more details on the training process - maybe a direct feed from the verbose outputs of the underlying models?

I've fixed a problem with no plot for models that have only one iteration.

The example plot for models with one iteration:
