How to make a raster plot for the binary response of two model?

I want to visualize my binary data in a raster plot. How can I plot ''ones'' as small line segments in raster plots?

my x-axis is going to be ''trial number'' , my y-axis is going to be response of two models ( [1 2]) and response = 1 should be like a small line segment in the plot.

Thanks.

I found my answer: I can use scatter plot with "|" marker instead of circle
