# Scatter Initially, the scatter plot will be empty. Drag and drop or double-click signals from the signal list to the x/y or color signal fields to add them to the plot. This is basically the same as you would do with a time series plot (see: [Signal List](/docs/marple-insight/user-manuals/visualisation/signal-list.md#add-signals)) . After adding some signals to the scatter plot, the plot should look something like this:

## Settings When you click on the settings wheel, there are ample options to further configure the scatter plot.

### **Resample input signals** You can turn on and off the resampling of the input signals and change the frequency of the resampling. See [Resampling](/docs/marple-insight/user-manuals/visualisation/resampling.md) for more details.

### Change the bullet size You can change the bullet size of the data points that are drawn on the plot to any desirable size. ### Change axes You can exchange the X and Y-axes by clicking on the button **cycle through the signals.** ### Alter the limits of the X and Y-axes Set the **limits** of the X and Y-axes

### Show subsampling grid You can turn on the display of a **subsampling grid.** This is useful for large datasets, as these are aggregated along a grid. ### Trend line You can apply a trend line, and choose whether you want the trend line to be linear, quadratic or cubic.

* An example of a quadratic trendline

* A linear trendline

* A cubic trendline

### **Filter outliers** To filter out outliers, you will have to add another signal from the signal list, and set a unit beyond which data points will not be considered. You can add multiple filtering signals.

### Add colour signal Add a colour dimension to the plot by adding a new signal and configuring lower and upper bound colors
