    A new curve entity will be added to the entity list.
  3. To rename the curve, right-click on the existing curve name and select Rename from the context menu.
    The curve is renamed and issued a unique ID number.
  4. You can choose whether to display the curve in the graph by clicking in front of the named entity.
  5. To delete a curve, select the appropriate curve and click the trashcan icon (), or highlight the name of the curve and select Delete from the context menu.
  6. To plot the curve:
    1. Click the Table tab on the middle left-side of the editor.
    2. Click into the first cell of the table in row 1 under the X column and type a value for the x-coordinate.
    3. Press the Tab to move to the Y column and type a value for the y-coordinate.
    4. Press the Tab again to move down to the next row and continue entering values as necessary.
      The curve is plotted in the editor.
  7. You can change various attributes of the plot by clicking the Property Editor tab:
    When checked, displays the curve.
    When report templates are overlayed, each overlayed curve is stored in a different layer.
    The curve (and shading, if areas are shaded) moves behind the grid lines of the plot, so that the grid lines are visible over the curve/shading. Autofit does not apply to the curve.
