Cerate a parallel plot with NIR data

frankderuyck — Wed, 21 Aug 2024 11:12:20 GMT

With gaph builder I would like to create a parallel plot with NIR data. I have tried but I get a very messy graph as shown in attached file, how can I make this plot like the one in the functional data explorer?

Which plot are you looking for? I don't see parallel plot in your functional data explorer script

Are you looking for something like this?

or this?

(these have been created by first stacking the data)

Hi @frankderuyck,

You will need your data in a stacked format to realize a similar plot with Graph Builder.

Here are the steps to have the graph you want :

Stack your datatable (all the wavelengths columns), change the names Label and Data as "Wavelength" and "Intensity" for example :

Script for this operation :

// Stack data table
// → Data Table( "Stacked_table_NIR" )
Data Table( "PARALLEL PLOT NIR" ) << Stack(
	columns(

	),
	Source Label Column( "Wavelength" ),
	Stacked Data Column( "Intensity" ),
	Output Table( "Stacked_table_NIR" )
);

Change the data type and modeling type of "Wavelength" as Numeric and Continuous.
Use Graph Builder, set "Wavelength" as X, "Intensity" as Y, and you'll get the Graph :

This graph is not a paralell plot, as a paralell plot has "independant" scales for each variable to allow for better pattern detection/recognition. More infos here : https://www.data-to-viz.com/graph/parallel.html.

You can find attached your datatable, with the scripts added for the stacked table and the Graph Builder (script in the stacked table).

I hope this answer will help you,

Thanks Victor, not possible to get one scale for parallel plots? There's not a lot difference among the NIR intensities.
