    Hey guys, I've had someone ask me about issues when using Scatter Matrix and Parallel plot. They upgraded from 9.1 to 9.2 and now have the error message "Plot parallel_coordinates does not support NOMINAL value column type ('attribute_57')." when running those two things. 

    Anybody have any idea why this is/have any potential fixes? 

    Thank you!

    As the error message says: They do not support categorical (nominal) columns, in this case "attribute_57" is the culprit.

    questions about new chart engine:
    - how do plot on the second axis? ( I want to put together a simple lift chart Prediction on the left axis, and exposure on the right axis)
    - how do i sort the x-axis categories? ( Im plotting a discretized variable with ranges from 1-7, the order in the graph is  2-3-4-1-6-5-7)

    - If you add a second (or more) y-axis, the plot config gets a new selection at the bottom which allows you to select the y-axis the plot should be tied to. Obviously, if you have more than 1 y-axis, you also should have more than 1 plot so you can actually make use of the other y-axis :)

    - The category values on the x-axis are taken in the order as they appear in the data. For numerical data we sort it, but for categorical we cannot make the assumption that it would be ok to sort it. So you need to pre-sort the data (e.g. via the Sort operator).
