Table WindowsAstroGrav Help /Window Types /Table WindowsVersion 5.1 Table WindowsTable windows let you view a simulation in the form of a table, with each object's data occupying one row of the table.
You can open a new table window by using the Window / New Table command, or by using the Window / Duplicate command on an existing table window.
You can select as few or as many objects as you like in a table window using combinations of the following commands.
You can also select a particular object using the Edit / Find... command.
The objects in a table are always sorted on one or other of the columns, with the sort column being indicated by a darker background color. If you want to sort the objects on a different column, Click on the column header, and the objects will then be sorted on the chosen column. If you want to switch from an ascending sort to a descending sort or vice-versa, Click again on the column header, and the objects' sort order will be reversed.
While you can sort on any one of the columns, some are much more useful than others. The columns that are most useful to sort on are as follows.
Sorting on the name enables you to easily select a particular object with having to resort to the Edit / Find... command, because the objects are sorted alphabetically.
Sorting on the type enables you to position objects of the same type next to each other.
Sorting on the color enables you to position related objects next to each other if you have color-coded your objects.
Sorting on the luminosity enables you to easily pick out the brightest and dimmest objects, as well as to see how the luminosities of the objects are distributed.
Sorting on the mass enables you to easily pick out the most massive and least massive objects, as well as to see how the masses of the objects are distributed.
Sorting on the radius enables you to easily pick out the largest and smallest objects, as well as to see how the radii of the objects are distributed.
Sorting on the lineage enables you to view to objects in the same order as they would appear in a tree that had all its nodes open, so that all objects were visible.
Sorting on the distance enables you to easily pick out objects that are very close to their parents, as well as to see how the distances of the objects from their parents are distributed.
Sorting on the speed enables you to easily pick out objects that are moving very rapidly relative to their parents, as well as to see how the speeds of the objects relative to their parents are distributed.
Sorting on the period enables you to easily pick out objects that are orbiting their parents very rapidly, as well as to see how the periods of the objects are distributed.
Sorting on the semi-major enables you to easily pick out objects that have very small orbits, as well as to see how the orbit sizes of the objects are distributed.
Sorting on the eccentricity enables you to easily pick out objects with near-circular or near-parabolic orbits, as well as to see how the eccentricities of the orbits of the objects are distributed.
Sorting on the inclination enables you to easily pick out objects with very high or very low inclinations, as well as to see how the inclinations of the orbits of the objects are distributed.
To show and hide groups of columns, you can use the items in the menu that is displayed when you click on the column selector (
) icon in the top-left corner of a table. There are the following eight commands, which are effectively on/off switches in the form of checkbox menu items and buttons.
Physical Elements which shows or hides the physical elements columns in the active table window.
Absolute Elements which shows or hides the absolute elements columns in the active table window.
Structure Elements which shows or hides the structure elements columns in the active table window.
Rectangular Elements which shows or hides the rectangular elements columns in the active table window.
Orbital Elements which shows or hides the orbital elements columns in the active table window.
Other Elements which shows or hides the other elements columns in the active table window.
Auto-Resize Columns which enables or disables automatic column resizing in the active table window.
Cell Detail Popups which shows or hides the cell detail popups when you move the mouse over cells in the active table window.
If you want to move a column to a new position, position the mouse on the column header, and then drag the mouse horizontally without holding any modifier keys down. The column will then move horizontally in response to your mouse drag.
If you want to change the width of a column, position the mouse on either the left or right border of the column header so that the mouse pointer changes to a 'resize' pointer, and then drag the mouse horizontally without holding any modifier keys down. The column will then resize in response to your mouse drag.
If you want to change the height of the rows, position the mouse on either the top or bottom border of a row leader so that the mouse pointer changes to a 'resize' pointer, and then drag the mouse vertically without holding any modifier keys down. All rows will then resize simultaneously in response to your mouse drag. It is not possible to have rows of different heights in the same table.
If you have a very long table, it can be difficult to find a particular object of interest, and so there is a 'scroll to row' feature to assist you. To use it, click on the row scroller (
) icon in the top-right corner of a table. This will display a small dialog window that allows you to specify what you are looking for, and AstroGrav will then automatically scroll vertically so that the specified object is visible. For example, suppose that you have a very large table and that you want to locate the asteroid 2003 WM118. You can sort on the names and then use the row scroller to specify something like 2003 WM or 2003 WM118 to quickly locate the asteroid.
To export a table's data in a form that is easily imported into a text editor, word processor, or spreadsheet application such as Microsoft Excel, you can use the export (
) icon in the bottom-left corner of a table. This will display a file chooser dialog that allows you to navigate your computer's file system to choose a location and name for the exported file. When the exported file is viewed in a spreadsheet application, there will be one column for each column of the table and one row for each row of the table, so that the exported data is presented in the same form as in the table. The export () icon duplicates the functionality of the Window / Export... command.
To quickly display this documentation, you can use the help (
) icon in the bottom-right corner of a table.
