ngx-explainers v16.0.1
Explainers
This project contains the Angular components for the visual explainers: 1. Shap Additive Force plot 2. Shap Additive Force Array plot 3. Custom: Shap Influence plot 4. Captum Image 5. Captum Text
The project is based on the original code by https://github.com/slundberg/shap and Captum.

Installation
- Run
npm i ngx-explainers
- Add
NgxExplainersModule
to the imports array - Use the one of the following component selectors:
<shap-additive-force>
<shap-additive-force-array>
<shap-influence>
<captum-image>
<captum-text>
API - How to use the components
shap-additive-force component input parameters:
Changing the colors of the plot. Requires an array of 2 colors.\
plotColors: string[] = ['rgb(222, 53, 13)', 'rgb(111, 207, 151)'];
Changing the x-axis type between log-odds (identity) or probabilities (logit).\
link: 'logit' | 'identity' = 'identity';
Setting the base value (middle point) for the plot:\
baseValue: number = 0.0;
Set the label(s) for the output variables\
outNames: string[] = ['Color rating'];
Hide the plot bars:\
hideBars: boolean = false;
Set the margin for the labels (labels show up when hovering the bars when not enough space to display the labels)\
labelMargin: number = 0;
Hide the label attached to the base value\
hideBaseValueLabel: boolean = false;
The data with the feature names and feature values\
data: AdditiveForceData;
