Introduction to Data Objects
When you're building an Astrato workbook, you'll add Data Objects to a sheet to display and manage your data. Data objects are split into two categories - Visualizations and Controls (Table 1).
Note: If you see an image that is greyed out, it means the object is being developed and will be added soon.
Table 1: Data Objects
Visualizations are data objects which display data from the data view powering your workbook.
Controls are data objects which manage visualizations.
You'll find data objects in the workbook editor toolbar (Figure 1).
Click the data object icon to open the menu.
Click the object you want to use, or drag it onto the sheet.
Click and hold to move the object within the sheet. You can also drag the edges to resize the object.
Figure 1: Add Data Object
Once you've added the data object, its settings will be displayed in the properties panel. You can use these settings to add your own data and apply changes to the object's appearance.
In Figure 2, we use the Data tab to apply a Dimension (a group of data values used to construct the chart) and a Measure (a unit used to calculate data in the chart) from the data set, replacing the test values. Switching to the Style tab, we change the Chart Type and select a Color Palette using the options in the Color menu.

In Figure 3 we see a control (a filter in this example) applied to the visualization and managing the appearance of the pie chart. Once the filter is applied, only the selected dimensions (Catalog and Government) channels are displayed.

There are several categories of settings for Astrato data objects, which are displayed in the properties panel when you select the data object. We've listed the settings available for each data object in Table 2.

Number, Pie Chart, Progress Chart
Bar Chart, Line Chart, Scatter Chart, Combo Chart, Heatmap Chart
Data, Style, Axis
Data settings are where you manage the data powering the visualization, adding fields from the data view as dimensions (the type of data you're displaying) and measures (the quantity of each dimension value). In addition, some data objects will have extra settings like adding Labels and Tooltip, displaying Reference Lines and also applying sorting or limiting functions.
Style settings control the look and feel of your chart. In the Chart settings, you can select a chart type, and there's even a Design Inspiration function to show you examples if you're not sure. The Color settings are designed to apply changes in a couple of clicks, either with the color picker or by choosing from a range of pre-defined palettes. There are also specific settings for each data object, including adding a Legend and selecting the Appearance of a data point.
Axis settings control the appearance of the axis for several data objects (see Table 1 above), where you can manage elements like your axis Title and Labels, define an axis Range and add Gridlines.
Layout settings are currently only used with table data objects and control settings for text in table cells.
