Colored-average NPM

colored-average Directive (Angular)

The colored-average directive is an Angular directive that allows you to dynamically colorize table cells based on the range of numeric values within the columns. You can specify minimum and maximum colors, and the directive will apply colors smoothly between them based on the values in the table.

Installation

You can install the colored-average directive via npm using the following command:

npm install colored-average

Usage

To use the colored-average directive, follow these steps:

Import the ColoredAverageModule in your Angular module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ColoredAverageModule } from 'colored-average';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, ColoredAverageModule],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

Import the ColoredAverageOptions in your Angular component:

import { Component } from '@angular/core';
import { ColoredAverageOptions } from 'colored-average';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
})
export class YourComponent {
  coloredAverageOptions: ColoredAverageOptions = {
    minColor: '#FF0000', // Minimum color (e.g., red)
    maxColor: '#00FF00', // Maximum color (e.g., green)
    applyToBackground: true, // Apply to cell background color
    columnOptions: [
      {
        index: 3, // Index of the column (0-based)
        minValue: 0, // Minimum value for this column
        maxValue: 100, // Maximum value for this column
      },
      // Add more columnOptions as needed
     ],
  };
}

Add the colored-average directive to your table's tbody element in your component's template:
```
```html
<table>
    <tbody [colored-average]="coloredAverageOptions">
        
    </tbody>
</table>
```
```
Now, the colored-average directive will apply color gradients to the table cells based on the numeric values within the columns.

Options

The ColoredAverageOptions interface allows you to customize the behavior of the directive:

minColor: The color applied to the minimum value in the column. Specify the color using a hexadecimal value (e.g., #FF0000 for red).
maxColor: The color applied to the maximum value in the column. Specify the color using a hexadecimal value (e.g., #00FF00 for green).
applyToBackground: Set this option to true to apply colors to the background of the table cells. Set it to false to apply colors to the text color.
columnOptions: An array of ColumnOptions objects that specify the minimum and maximum values for each column in the table. This is useful for cases like pagination where you want to set specific bounds for a column without affecting others. The ColumnOptions interface has the following properties:
- index: The index of the column (0-based).
- minValue: The minimum value for this column.
- maxValue: The maximum value for this column.

You can adjust these options to achieve the desired visual effect for your table columns. For example, you can create a gradient effect from red to green for numeric values in a table.
