Graph Builder Overlay values

luccasinaccio — Wed, 07 Aug 2019 23:45:11 GMT

I'm having a problem with the interval of values of the overlay (SAL) in the Graph Builder.

I want to specify my own interval of values but the program keeps chosing the interval instead of me, and I don't know how to change it.

Can someone help me with this?

There are 2 ways to do this that I can think of at this time

Create a new character column based on the Sal column, giving it the values you want for the overaly, and then use the new column as the overlay column.
Use the Value Labels column property for the Sal column, and specify ranges for the Value Labels.

Luccas:

I would recommend dropping SAL on Color instead of Overlay since SAL is a continuous variable. That way you can assign a meaningful continuous gradient color theme like cool to warm (blue to red). See example of 6 bara water density vs entropy colored by temperature.
Another tip for when you have many categories to overlay: use the color theme Spectral. Why? Lots of colors (so you don't have discern between 5 shades of light green...) and it follows the rainbow. In primary school we all (English speakers) learned ROYGBIV. This is great for timestamps as overlay: purples are in the past and reds are now.

Thanks for your replying. The secund tip is really good but it didn't work as well, and I don't know why. Anyway, thanks!

This was good, but it inspired me to do something I liked even more. I right clicked on Sal variable on the left hand side of the Graph builder window, then I chose Transform - Round and then it created a new temporary variable that had any bins I wanted (same range for all bins, though).
