MSO46 Dotted Line on Display

Can the dotted line on the MSO46's screen, right under the triangle where the trigger position is, can be turned off?

The dotted line can be removed:

Double-tap on the screen over an open graticule area. This will open the Waveform View configuration menu. Select the drop-down menu under Graticule Style and select None. This option will remove all of the unit dotted lines on the screen
