How do I combine multiple plot into a single graph

[#1]

Hello there,

I tried to combine multiple plots into a single graph, I tried to use graph builder but the best I can do is 3 separate graphs, I want them to be together, for example, 3 lines in a graph just for better visual comparison. Please help out as I am stuck with my research work :\

Thanks,

Charlie

after both have been moved:

Other option. Remove all variables from Y-axis, select all variables of interest from the column list:

and drag and drop them at the same time to Y-axis:

I tried changing the data type to continuous and it works, whereas it doesn't work in ordinal. Kinda weird though but thanks for your insight.
