You can discover insights from your data by creating visualizations. By exploring data from different perspectives with visualizations, you can identify patterns, connections, and relationships within that data and quickly understand large amounts of information.

You can create graphics similar to the following example that shows how humidity values over time.
Creating visualizations
You can build a chart by selecting a predefined chart type from a gallery or by combining basic elements from the provided chart type options (for example, axes and bars). See Visualizations layout and terms for descriptions. Using the gallery is the preferred method for new users. Start by using the predefined charts. For more information, see Building a chart from the chart type gallery .
To create visualizations that use an asset from your project:
- On the Assets tab of your project, click Data asset in the list of asset types, and select a data asset.
- Click the Visualization tab.
- Select a chart type from the options that are listed and input your preferences in the graphical
options pane.
Available chart types are ordered from most relevant to least relevant, based on the selected columns. If there are no columns in the data set with a data type that is supported for a chart type, that chart will not be available. If a column's data type is not supported for a chart, that column is not available for selection for that chart. Dots next to the charts' names suggest the best charts for your data.
As you are building the chart, the canvas displays a preview of the chart. The preview uses the actual variable labels and measurement levels that are representative of your actual data.
- To save your visualization, select ACTIONS > Save visualization to project.
Your saved visualization is listed as a Visualization asset in your project. Graphical charts are generated based on a sample data set of up to 5000 records. To generate a chart based on a full data set, edit the visualization asset.
You can view or edit the visualization by clicking the name of the visualization that is listed in the Visualization assets of your project. On the Layout tab, you can arrange a layout of multiple charts and generate an output in PDF format.
