Plot Editor

The graph on the right shows the plot as it appears in the original graph. Its style can be changed using the plot legend functions. Any such changes can be reverted while in the editor by pressing the Reset Style button.

The two arrays on the left (X Array and Y Array) display the plot data (X and Y coordinates of each points). Both arrays are linked, therefore moving the scrollbar on one array also moves the scrollbar on the other, guaranteeing that each X value is matched by the correct Y value and reciprocally. However, this is only true if both arrays have the same size. This can be checked by looking at the X Array Size and Y Array Size indicators below both arrays.

The arrays can be modified in two different ways (each array is modified independently).

1. Whole Array modification

• • Empty Array: this is achieved using the Empty Array context menu item shown when right-clicking on the array scrollbar.

  • Copy/Cut Data: this is achieved using the corresponding context menu items shown when right-clicking on the array scrollbar.

• Paste Data: this menu item is only available after either of the above two actions (Copy or Cut).

These operations can be used to replace the abscissa (X) array of a plot with that of a previously edited plot (provided its abscissa array has been copied).

2. Single Element modification

• • Editing elements individually: a value can be typed in the different cells.

  • Delete Element/Insert Element Before/After: this is achieved using the corresponding menu items of the context menu item shown when right-clicking on any of the array elements.

All the modifications to both arrays can be reset by pressing Cancel Data Edit.

To quit Plot Editor without applying any of the changes to the original plot, press Cancel or click on the window close box.

To apply the changes on the original plot, press OK.

Important Note: while the Plot Editor window is opened, most of the calling application's GUI elements are unresponsive. It is possible to open another window or switch to a different panel, but selecting any action in these or the main menu will not be followed by any actual action until after the Plot Editor window is closed.
