Creating curves


Post-Pro functionality allows to create Curve lines on the basis of the data taken from tables, and to display these curves in form of 2D plot using Plot2d viewer. Plot2d viewer is described in the documentation on GUI module.

To create curves:

  1. Right-click on the required table in the Object Browser.

  2. From the pop-up menu choose Create Curves option.

  3. The following dialog box will appear:

    This dialog box has the form of a table; each row of this table represents one column of values of the imported data table.
    To construct curve lines, you should choose at least two columns of the data table by checking them in the Axis part of the dialog box:

    • H (horisontal) - the values of this column will correspond to X-coordinates of the curve.
    • V (vertical) - the values of this column will correspond to Y-coordinates of the curve.

    The column Assigned allows to represent the values assigned to the points of the curve (possible for V-rows only). Any row, even coinciding with the current or empty (no values assigned), can be represented. All values are indicated with tool tips over the corresponding curve points in the Plot2d viewer.

    To define the Attributes of your curve remove the checkmark from Auto assign (if it is checked, default attributes are taken) and select:

    • Line type (None, Solid, Dash, Dot, Dash - Dot, Dash - Dot - Dot),
    • Line width,
    • Marker type (Circle, Rectangle, Diamond, Rightward, Leftward, Downward & Upward Triangle, Cross or Diagonal Cross),
    • Color (using the standard Select Color menu).
    Note:
    From this dialog box you can create several curves for the columns of your data table with the same units. Post-Pro allows to display at once up to 200 curves.
  4. Click OK to create your curves with the given parameters. Post-Pro will automatically create your curve or curves in the structure of the study under two SALOME objects:
    • SALOME table object,
    • Plot2DView object: SALOME container of curve lines which will be created automatically.
