AG Chart Component Documentation

Component Overview

This module is used for creating dynamic charts in Wappler. It provides various properties for configuring the appearance and behavior of the charts.

Component Properties

AG Chart Properties

1. ID: Unique identifier for the chart. (Required)
2. Data Source: The data source for the chart, e.g. SC or JS data source. (Required)
3. No Auto Load: Set to true to disable auto-load of the chart. (Default: false)

AG Chart Options

• Chart Type: Select the type of chart to be displayed. Currently supported: Line, Column(Bar), Pie, Percentage and Area.
• Chart Theme: Choose the visual theme for the chart. Options include Default, Dark, Material, Pastel, and Custom.
• X-Axis Key: The data key for the x-axis of the chart (Optional).
• Y-Axis Keys: Comma-separated data keys for the y-axis of the chart (Optional).
• X-Axis Title: Title for the X-axis of the chart.
• Y-Axis Title: Title for the Y-axis of the chart.
• XY Axis: Enable the XY axis for a single series in the chart.
• Stacked: Enable stacking of plots in the chart.
• Strokes: Enable or disable outline strokes for fills.
• Tooltip Roundoff: Enable rounding off of Y values in tooltips.
• Series Labels: Enable or disable series labels.
• Series Labels Font: Choose the font weight for series labels.
• Series Labels Font Style: Choose the font style for series labels.
• Hide X Axis Label: Enable to hide the X-axis label.
• Hide Y Axis Label: Enable to hide the Y-axis label.

AG Chart Legend

• Legend: Enable or disable the chart legend.
• Legend Shapes: Choose the shape of the legend markers (Circle, Square, Cross, Triangle).
• Legend Spacing: Adjust the spacing between legend items.
• Legend Position: Choose the position of the legend (Bottom, Top).
• Humanize Y Axis Legends: Humanize Y-axis legends for better readability.

Inner Labels

This allows configuring Inner labels in a Percentage Pie chart.

• Inner Labels: Checkbox to display the inner labels settings
• Inner Label Color: The color of Inner Percentage. (Default: "red")
• Inner Label Font Size: The font size of inner label values. (Default: 40).
• Inner Label Title: The Title for the Percentage Value. (Default: "Coverage")
• Inner Label Title Font Size: The font size of the Title for the Percentage Value.
• Inner Label Title Margin: The margin of the inner label title.
• Inner Circle Fill Color: The fill color of the inner circle. (Default: "green")

Action Attributes

Load

• Mainly to be used in conjunction with "No Auto Load" enabled so that you can load only when certain conditions are met.
• Use Case: Used when you're awaiting the population of specific elements or data before loading the chart. It's also useful for refreshing the chart intentionally.

Usage

The module can be used to generate AG Charts given a data source.

It Accepts Data sources in 2 formats:

1. As an array with key values, one for the terms, the other for the count

 [
  {
    "category": "BALLONS",
    "count": "533"
  }...
 ]

In the above case, we can enable the XY Axis toggle provided in the UI module so that it can generate a series for the same based on the values. This is essentially helpful for queries such as Top 10, top 50, etc.

2. For the 2nd type of Data, the below format is accepted:

[
  {
    "month": "2026-12",
    "checked": "1",
    "flagged": "1"
  },
  {
    "month": "2025-01",
    "checked": "1",
    "flagged": "1"
  }...
]

We can feed this directly to the module data source. Note: Setting xkey and xkeys from the UI is optional, it takes the first key for x and subsequent keys as ykeys

For PostgresSQL a query similar to below can be constructed:

SELECT
    JSON_AGG(
        JSON_BUILD_OBJECT(
            'checks', checks,
            'count', count
        )
    ) AS result
FROM (
    SELECT
        'checked' AS checks,
        COALESCE(count(1), 0) AS count
    FROM
        user_data
    WHERE
        AND created_at >= NOW() - INTERVAL '1 DAY'
    UNION ALL
    SELECT
        'under_review' AS checks,
        COALESCE(SUM(under_review::int), 0) AS count
    FROM
        user_data
    WHERE
        AND created_at >= NOW() - INTERVAL '1 DAY'
    UNION ALL
    SELECT
        'rejected' AS checks,
        COALESCE(SUM(rejected::int), 0) AS count
    FROM
        user_data
    WHERE
        AND created_at >= NOW() - INTERVAL '1 DAY'
) AS subquery;

Then enable the XY axis to display the data

Example usage of Percentage Chart:

Given below input data below:

[
  {
    "name": "Covered",
    "count": 17000
  },
  {
    "name": "Not Covered",
    "count": 3000
  }
]

• Set Chart Type to "Percentage".
• Set the Inner Label Settings as required, i.e. the Inner Label title, Font size, etc. or leave defaults.
• Set the Inner Radius Offset to -20.
