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.

- 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.
