Hello, I want to create a signal in Simulink manually. I came across the Signal Builder block but I cannot figure out how to add more data points so that I can drag the points to create a signal of different amplitudes. There is not much information about this block in Help nor the manual. Could anybody please show me how to do that? Thanks

While hovering over the curve, use shift+click to add a data point.

Thanks. How did you know?

I wish that information was at least shown on the help.

Ideally, there should be the options of "Add point" and "Delete Point" in the right-click pop-up menu.

I second this, this is exceptionally unintuitive...

Hold shift key. Then left-click on the signal where you want to add a point.

You can define the signal in excel and import it into signal builder (using File->import from file). This is by far the easiest way.

Did you find a way to do that I'm also having trouble for doing that. :)

I just came across this feature today. You can specify a time column and a data column in excel as follows for your case:

Then, using the Signal Builder block, import the data and everything should be as expected

Thanks for all, it helps me a lot. Actually from the help comment of signal builder, there war no such info. I am wondering, how you figure out this kind of features?
