Using Data Markers

You can click on the response to add plot data markers that display information about particular points on the response.

To move a data marker, grab its black square at the corner of the marker. Dragging the marker with your mouse changes the Frequency and Magnitude values.

To change the properties of a data marker, right-click on the marker to display the properties menu:

• Alignment--Change the position of the marker. Available options are top-right, top-left, bottom-right, and bottom-left.
• Font Size--Change the font size.
• Movable--Allow the marker to be moved on the response.
• Interpolation--Select Nearest to force the marker to snap to nearest point along the plotted curve. Select Linear to interpolate between points along the plotted curve.
• Track Mode--Restrict the marker to be movable in the x, y, or xy direction.
• Delete--Delete the selected marker.
• Delete all--Delete all markers.
