## What is the Correlation plot?

The *Correlation plot* is used to visualize the relationship between feature and numeric attribute values for each sample or cell. The y-axis is the feature and the x-axis is the numeric attribute. Points on the plot are cells or samples.

## Viewing the Correlation plot

The correlation plot is available on [Correlation analysis](https://help.connected.illumina.com/partek/partek-flow/user-manual/task-menu/correlation/correlation-analysis) and [ANOVA/LIMMA-trend/LIMMA-voom](https://help.connected.illumina.com/partek/partek-flow/user-manual/task-menu/differential-analysis/anova-limma-trend-limma-voom) (if a numeric attribute is included) task reports.

## Configuring the Correlation plot

The correlation plot can be configured using the control panel to the left of the plot (Figure 2).

Figure 2. Correlation plot

The points on the plot are the cells or samples.

The feature ID is shown in the plot title.

The x-axis is the selected numeric attribute.

The y-axis is the normalized counts for the feature.

The points can be colored, sized, connected, and labeled using the drop-down menus in the control panel. By default, the points are colored by the first numeric attribute.

To switch the numeric attribute on the x-axis, use the *X-axis* drop-down menu.

The linear regression line is shown on the plot as a grey dashed line.
