# Combo chart (chart type)
* A **Combo Chart** is a hybrid visualization that combines two types of charts, typically a **Bar Chart** and a **Line Chart**, to display data with two different types of measures on the same axis. This allows for a more comprehensive comparison of datasets that are related but may have different value ranges or types.
* First, click on any "+ Add widget" button to add a widget.
* Click on the Combo chart option.
* Click on the Add widget button to proceed.
* Choose the available Collection or Connection of the data model that has been added.
## Set up your Combo chart
* Click on the X-axis dropdown box and select an available column.
* If you choose a Date type column, the [Time series mode](/docs/dashboard/widget-types/bar-chart-type/bar-chart-time-series-reference-date-preset-and-compare-to-the-past.md) will auto apply to the Combo chart.
* Continue to choose any available column in the Y axis
* After the X Axis and Y Axis columns are selected, the Combo chart of the data model will be displayed.
* The Sum formula will be auto-selected. You can change to other [Formula](/docs/dashboard/footer-formula.md) options by clicking on its dropdown box.
* If no column of the same type is grouped, you can change it view to Bar or Line chart.
* You can also change the axis of the column in the Y axis.
## Group by column
* Click on the See more button then click the Group by option.
* Choose the available column to group by.
* Each column shall be grouped based on the selected column.
{% hint style="info" %}

{% endhint %}
## Change to the Combo chart type from another widget
* The Combo chart option can be selected by opening the Settings slider and then clicking on the Properties option.
* Click on the View type dropdown and choose the Combo chart icon to begin configuring your data model to the Combo chart.
