Train/Test selection for a user defined row number for new feature

xntang88

As explained in the title, I wonder whether it is possible to add a user-defined row number in train/test selection (currently it has 100, 1000, etc. e.g, we want to define a specific row number) in the new released version.

Also, it would be helpful if a perfect line is drawn for the plot of observed vs predicted in the plot.

Superimposing a perfect y=x line on the observed vs predicted plot may not be useful for all error metrics. Take for example the Correlation_coefficient metric, which can potentially find a candidate function with perfect correlation, but scaled by a factor other than unity, and with a y-offset.

Added in v2.21. Just select "Custom rows" under "Train/test split" and then manually type your desired number in the new input field that will appear.

The y = x line has also been added. Following @PGS's suggestion, this line is disabled when the search metric is "Correlation coefficient".
