# Modifying Data Components

The **Chart Components** section allows you to refine and customize how your data is visualized. Depending on the selected chart type, different configuration options will be available. Below are the key components:

1. **Dynamic Data Mapping Based on Chart Type**
   * When a chart is selected, the relevant data mapping fields will be displayed.
   * Example: A **line chart** requires `X-Axis`, `Y-Axis`, `Pivot`, `Order By`, and `Filter` fields, whereas a **bubble chart** will have different data mappings.

2. **Selecting and Modifying Data Fields**

* Click on a input to open a selection tray.
* Multiple fields can be selected or removed from the tray.

* Click the `X` mark on a field (colum) to remove it.

1. **Creating Custom or Calculated Fields**
   * Use the **custom metric** option to define a calculated field.
   * A pop-up will appear where you can write a formula and save it.
   * If an error occurs, AI will automatically prompt you to correct it.

3. **Using Pivot Columns for Advanced Analysis (more details in next section)**

* Pivoting allows data to be split by a selected category.
* Example: To view **sales by market per month**, you can set:
  * `X-Axis`: `Month`
  * `Y-Axis`: `Sum(Sales)`
  * `Pivot`: `Market`

4. **Sorting with "Order By"**

* The **Order By** field controls the arrangement of data points.
* Example: Order sales **by year (ascending or descending).**

5. **Filtering Data for Dynamic User Control**

* Filters in this section allow dynamic filtering at the **chart view** level.
* Users can select multiple filters for interactivity.
* Default values for filters can be set by clicking on a **filter chip**, which opens a pop-up for customization.

6. **Final Step: Always Click "Apply"**\
   After making any changes, clicking **"Apply"** is a mandatory step to refresh and provision the dataset for visualization. Without this step, changes will not be reflected in the chart.
