# Chart Card

Charts are a great tool to visually summarize a large amount of data and are the main recommendation when creating Dashboards that aim to directly show a specific analysis context.

Chart Cards can be used to create different types of visualisations, depending on the objective being pursued. To create a chart card, you start with a selection of data fields (as with all other data cards) and the "Visualization" tab is where you select the type of chart.

Currently the types of charts available are:

* Line chart
* Area Chart
* Vertical bar chart
* Horizontal bar chart
* Stacked vertical bar chart
* Stacked horizontal bar chart
* Mixed graph of lines and vertical bars
* Doughnut chart (donut)
* Pie chart
* Radar chart

Each type of chart includes additional blocks and settings available. For example, vertical bar charts include the "**Dimension**" block (associated with the horizontal axis), the "**Metrics**" block (associated with the vertical axis) and optionally the "**Break by**" block to distribute the value of a metric among the different values of a dimension.

There are many options to set up a chart, and some of them are particular to each type of chart:

* Show legend and in which position (up, right, down or left)
* Show pop-up description (tooltip)
* Label data values on the chart and in what format
* X-axis configuration
* Y-axis configuration

As with other cards, each field has its own configuration, in which you can specify details such as:

* Field labels
* Sort of values
* Formats of values
* Colours and styles

Options and results that can be achieved in terms of charts, are very broad and open to specific needs or to the imagination of the user.
