Scatter plot widgets
- Juan Tomás Alonso Nieto (Deactivated)
The scatter plot widget is often used to visualize the correlation between two variables as it depicts points in a two-axis diagram at the intersection of their values. This is very useful to spot trends easily and analyze matrix variables because you can see at a glance the overall distribution of the different data combinations.
What data do I need for this widget?
The source query must contain columns with at least two numerical values, which will be automatically recognized and displayed in the diagram. If the query contains more than two, the first two will be selected automatically although you can change the selection in the widget's visual settings, as explained below.
Widget settings
To edit the widget settings, you must first be in Edit mode.
Click the widget title bar to open its settings. Alternatively, the settings are accessible via the Ellipsis icon → Edit. The widget settings are contained in three tabs, Data, Visual, and Raw.
The settings in the Data and Raw tabs are described in the Create a widget article, while the Visual settings are explained below:

Tips for using a scatter plot chart
Here are a few tips to get the most out of your scatter plot chart:
Hover over a point on the chart to view a tooltip with the variables and their values.
Click and drag to delimit an area to zoom in on and the chart will show only those values included inside. Click the Reset zoom button that appears at the top right to go back to the default visualization.
Hover over a data series in the chart legend to dim the rest of them down in the chart or click it to hide it or show it. You can also click the Hide all Series/Show all series button at the top right corner to hide/show all the series in the chart.
