Grouped Multi Line Scatter Plot from Loop

[MagnoChris]

Hello,

I have a numerical data set from a parameter space sweep based on simulation results.
Some columns are ‘input parameters’ for the simulation, while others are ‘result fields’.

I want to create a scatter plot for each group of a set of parameters with a legend referring to the parameternames and values.

I need to be able to change both parameters and fields easily and without having to make many adjustments.

Here is a little demo of what i already tried to achieve:

Thank you in advance,

Chris

You can simplify this significantly, no loop is needed

I suggest using a Color Manager node followed by the Scatter Plot view.

1. Color Manager: Assign colors to your “Parameter” column here.
2. Scatter Plot: Connect the data here. In the configuration, select your “Parameter” column for the Color dimension.

This will create a single chart with 4 color-coded groups and a legend.
