If several of your files describe the same items, you can merge them into a
Data object. Examples of files that make
sense to merge together include:
Two or more images that are pixel-aligned to each other
Several catalogs whose rows describe the same objects
For multi-dimensional visualizations (like a scatter plot, or an RGB image), merging datasets allows you to combine attributes from two different files into a single visualization. It also guarantees that any subset defined using attributes from one file can be applied to the entries in another file.
How to merge datasets¶
You can merge datasets by highlighting the relevant datasets in the left panel, right-clicking, and selecting Merge datasets.
To merge datasets programmatically, use the
Datasets should only be merged if each element describes the same item in each file. Consequently, all merged datasets must have the same number of elements.
