# Building charts from Configuration pane

The chart configuration in Tellius is designed to be intuitive and flexible, allowing you to easily customize data visualizations to fit your specific needs. 

## Fields and their usage

Here's a brief description of prominent fields found in the **Configuration** pane:

<figure><img src="/files/J9LeNNh3FpN2DJ45orJ0" alt="" width="214"><figcaption><p>Configuration pane for bar chart</p></figcaption></figure>

* **Measure**: This field is for the numerical data you want to analyze, like sales or revenue. It defines the basis of your chart's quantitative analysis.\
  Example: *<mark style="color:orange;">Profit, Revenue, Quantity</mark>*
* **Dimension**: Dimensions are the categories you're measuring by, such as time periods, regions, or product categories. They provide context for the measures.\
  Example: *<mark style="color:orange;">Category, Market, Country</mark>*
* *<mark style="color:orange;">Dimension (Date): This field accepts only date-based columns.</mark>*\
  ➤ Set a **time grain** (e.g., `YEARLY`, `MONTHLY`, `DAILY`) to define the sparkline cadence.

{% endhint %}

* **Color By**: Assign colors to different segments of your data, such as regions or products, to visually distinguish and analyze patterns and trends.\
  Example: *If you select the column <mark style="color:orange;">"Region"</mark> for <mark style="color:orange;">Color By</mark> field, then the chart uses different colors to represent sales data from different geographical areas.*
* **Sort By**: Determines the order of data presentation in your chart, which can be ascending or descending, helping to prioritize or sequence data points.\
  Example:  *If you select the column <mark style="color:orange;">"Sales" (descending order)</mark> for <mark style="color:orange;">Sort By</mark> field, then the chart prioritizes higher-selling items.*
* **Tooltip**: When hovering over elements of the chart, tooltips provide additional information like exact figures or related data, enhancing the detail available on demand.\
  Example:  *If you select the column <mark style="color:orange;">"Units sold"</mark> for <mark style="color:orange;">Tooltip</mark> field, then the chart shows the exact number of units sold in tooltip when hovering over it.*
* **Unused**: Here, you can store columns that are currently not in use but might be needed for future reference or analysis because the chart type or other chart configurations changed.
* **Pagination (Enable/Disable Toggle)**: This controls whether your chart breaks data into pages or shows all data at once, useful for managing large data sets.
* **Show Rows (Number Field)**: Decide the number of rows to be considered for preparing the chart, focusing on a specified amount of data entries.
* **Include Nulls (Checkbox)**: This option includes or excludes null values from your data, allowing you to decide whether to consider or ignore incomplete data points.\
  Example: *In a product performance analysis, <mark style="color:orange;">include nulls</mark> to see all products, even those without any sales.*&#x20;
* **Dual Axis (Checkbox)**: Enables you to plot two measures on the same chart with separate Y-axes, useful for comparing different types of data.\
  Example: *Display <mark style="color:orange;">website traffic (first axis)</mark> alongside <mark style="color:orange;">conversion rate (second axis)</mark> for a digital marketing analysis.*
* **Show Query Time (Enable/Disable Toggle)**: Displays the time taken by Tellius and other external engines to execute the query.

{% hint style="info" %}
Please note that each type of chart will have a unique configuration. Not all charts will have all the above-mentioned fields. For example, KPI charts will have only ***Measure***, ***Tooltip***, and ***Unused*** fields for simple yet effective visualization, whereas bar charts offer a wider range of fields to provide more detailed and complex visualizations.
