# Common Chart Configuration When setting up a visualization, you can select how your data should be aggregated. These aggregations define how raw values are summarized and displayed in the chart. The available options include: * **Sum** – Adds all numeric values in the column. * **Average** – Calculates the arithmetic mean of the values. * **First** – Returns the first value in the column based on the dataset order. * **Last** – Returns the last value in the column based on the dataset order. * **Maximum** – Returns the highest numeric value in the column. * **Minimum** – Returns the lowest numeric value in the column. * **Count** – Counts the total number of rows. * **Count Distinct** – Counts the number of unique values in the column. * **No Aggregation** – Displays the raw data without summarizing. Secondary values cannot be aggregated in this mode. All aggregations are applied **per group of dimensions** defined in the chart configuration—most commonly labels or x-axis values, but they can also include other groupings like segments or packs. {% hint style="info" %} **Hint** Dimensional columns support only the *Count* and *Count Distinct* aggregation methods, as other types of summarization are not applicable. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs-v3.toucantoco.com/visualizations-and-layouts/creating-visualizations/common-chart-configuration.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
