Property Editor - Curve

In treeview -> plot -> curve
Lets you edit the attributes of a curve on a plot. You can also set defaults for how Adams PostProcessor creates curves, as explained in PPT Preferences - Curves.
 
Note:  
In addition to setting a curve's properties, you can edit the data in the curves. Learn about Performing Calculations on Curves.
 
For the option:
Do the following:
Legend
Enter the text to appear in the legend associated with this curve. Adams PostProcessor displays the legend with a short line segment illustrating the color and line style of the curve. If you updated your plots, Adams PostProcessor creates a second legend, called the simulation legend. You modify the simulation legend text separately. For more information on modifying legends, see Modifying Legend Properties. For more information on the types of legends, see Updating Plot Data.
Tip: You may want to expand the width of the Property Editor so you have more space for entering the legend text. To expand the property editor, point to its right border. When the cursor changes to a double-sided arrow, drag the cursor to increase the property editor's size.
Line Color
Select the Line Color for the text and curve.
Line Style/Line Weight
Select the type of line style and weight for the curve. The weight values range from 1 to 5 screen pixels. Set the line style to None so that Adams PostProcessor does not display the curve line. If you selected to display symbols along the curves, the symbols still appear when you turn off the curve line.
Symbol/Symbol increment
Select the type of symbol that you want at data points along the curve and select how often you would like the symbol to be displayed along the curve.
Hotpoints
Select to turn on Hotpoints that let you manually edit the data points in the curve. You can also control how you edit the hotpoints, only vertically or only horizontally, so you have greater control. For more on hotpoints and manually editing curves, see Manually Changing Data Point Values.
Select one of the following:
No - To have no hotpoints displayed.
Yes - Turn on hotpoints, to allow the editing of the data points in any direction.
Horizontal - Turn on hotpoints, but only allows the editing of the data points in the horizontal direction.
Vertical - Turn on hotpoints, but only allows the editing of the data points in the vertical direction.
Note: You can use the Hotpoints tool on the Curve Edit toolbar to override this setting. See Displaying the Curve Edit Toolbar.
