Settings in the "Risk-Return Matrix" widget
Alternatively, you can use the "Settings" command in the widget menu.
By using the settings of the widget, you can show the mean value of the securities in the matrix, for example, for the securities in the "DAX" index, you can also show the DAX. This is then displayed in a different colour.
To do this, select the "active" checkbox and confirm the setting with the "Save changes" button.
For an example, see Risk-Return Matrix.
