# "Line in linear regression"

Hello,

I am new to this Forum but I have searched extensively for this feature but did not find it so I post it as a suggestion.

When doing linear regression I would like to plot the resulting line automatically. The way I am doing it now is to get the slope/intercept from the model and then program it in another operator to get a new attribute column that I then plot. Quite cumbersome, I would say.

One way to develop this is to be able to refer to results from the previous operator. Illustrating this for the Linear Regression calculation:

y = m x + b

OperatorRegression_Result_01 x attribute_X + OperatorRegression_Result_02

This would apply for any result from any operator, of course, not only Regression operator.

I am forcing open doors here and all this can be done in an easy way? (not involving other programming, XML etc.)

Best regards and thanks for an awesome product, RapidMiner!

To actually plot a line instead of dots try the series plotter, or go directly for the advanced charts.
