Remove drawed lines with Repeater on ComboBox value changed

[anda_skoa]

The repeater will always create as many element as its model says.

Since your model is a simple number, just decrement that number.

Once some number of lines is drawn, they will not be deleted when a smaller number of lines is given to the model. So how to delete them and start drawing again?

[anda_skoa]

A Repeater that operates on a primitive model, a number or a list, will always recreate the number of delegates for the current model's count.

I.e. if the number changes from 1 to 2, it will delete all delegates and create 2.
If the number changes from 2 to 1, it will delete all delegates and create 1.

In your code the most puzzlng thing is why you create a new additional Analysis component every time the combobox changes.
