Close : Use this option to close a diagram window. To show the window again go to the Quick access menu and use the ’Window’ function. The default settings in the diagram menu are as shown in the image above. SKNKNKO cbcilt Çá~Öê~ã éêçéÉêíáÉë Choosing ’Properties’ from the diagram menu a new window is opened offering all tools for customiz- ing the diagram. There are two tabs for editing the curve properties and the properties of the axes. `ìêîÉë At the top of the window some buttons are placed for adding and removing curves as well as for saving and loading them: In the left part of the window an overview of all curves is shown. Use the square to the left of the curve name to show or hide a curve in the diagram. The settings to the right always refer to the curve currently selected in the list. Please note that for chang- ing the properties only one curve may be selected. In the ’Title’ input field you can specify the curve title to be shown in the diagram. Beneath the title there are five switch toggles and an input field. Their func- tions are as follows: Figure 6.3 Diagram properties - curves tab. Table 6.1 Diagram properties - buttons Add a curve loaded from a file : Load one or several curves in *.pow file format. Save a curve to a file : Save the selected curve to a *.pow file. Add a curve based on an expression : Opens the ’Analytical expression editor’ for adding analytical functions. See detailed description below. Delete the curve from the diagram : Remove the currently selected curve(s) from the diagram. Edit special curve properties : Invokes the ’Analytical expression editor’ for editing an analytical function. See detailed description below.

cbcilt SKM `ä~ëëáÅ ö TV SKN fåíêçÇìÅíáçå Analytical expression editor In this window, which is invoked by the button, analytical expressions can be prepared for the use as diagram curves. Besides the basic arithmetic operations scientific mathematics are possible, too. All functions have to be written for x as argument. See the online Help for a detailed list of operators. Reference data The reference data section can be used to load and edit time-varying reference data (measured data), and to compare to the computed results in scatter plots. The scatter plots drawn here show the values at the different time stages for one single curve. ^ñÉë The second tab in the diagram properties window provides the possibility to customize the diagram axes. The settings for the abscissa (’ x -axis’) are located in the left part, the ones for the ordinate (’ y -axis’) in the right part. Title and unit describe the labeling of the axes. The scaling of both axes can be set individually, either to ’Linear’ or to ’Logarithmic’. The shown range of values is automatically adapted to the currently shown functions by default (’Auto’). Alternatively it can be ’Fixed’. In the latter case the minimum and maximum values have to be specified.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
