Hi David,

No, sorry, we haven’t provided that capability in CODAP. However, in many situations, the desired plot can be created through a transformation of the data. The screenshot I’ve attached shows the basic idea. The values of the two attributes in the dataset at left are what you want to plot on the same graph. Using the Pivot Longer transform from the builtin plugin Transformers, you create two new attributes, one for year and another for the values. Now you can make the graph!

Hope this helps,

Bill
