Maps specific category values to hex colors. Each key in the params object is a category name and each value is a hex color code (e.g. “#FF0000”). Categories not explicitly mapped will use the default color palette. This is a UI configuration step that affects how the project is displayed in Graphext. It applies to the dataset referenced in its inputs. If your recipe produces multiple datasets (e.g. a filtered dataset that is then passed to create_project alongside the original), you need to add separate configure steps for each dataset you want to configure.

​
Usage

The following example shows how the step can be used in a recipe.

Examples

Change the colors of the category ‘positive’ to white, ‘negative’ to black and ‘neutral’ to green
configure_category_colors(ds.sentiment, {
    "postive": "#FFFFFF",
    "negative": "#000000",
    "neutral": "#00ff00" 
})

​
Inputs & Outputs

The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced by name e.g. "churn-clf").
​
column
column[category|list[category]|text|boolean|list[boolean]]
required
Column to be configured.

​
Configuration

The following parameters can be used to configure the behaviour of the step by including them in a json object as the last “input” to the step, i.e. step(..., {"param": "value", ...}) -> (output).

Parameters

​
Items
string
Category colors. A mapping of category names to colors.Values must match the following regex pattern:
^#([a-fA-F0-9]{6}|[a-fA-F0-9]{3})$
