Data Sets Window
The Data Sets window displays a table with one row per dataset and 12 columns:
| Column | Description |
|---|---|
| Name | Name of the dataset. (*) |
| Information | Name of the source packet, the description of the parameter (see File Formats) or other information for this set of data. (*) |
| Type | FLT for numerical values, LABEL for state values. |
| Units | Units name (used as Y axis label in graphs), or none. (*) |
| X Label | Label for the dataset's X axis. (*) |
| Data X | Name of the data vector for X values (usually dates). (¹) |
| Data Y | Name of the data vector for Y values. (¹) |
| Min | Smallest Y value in set. |
| Max | Largest Y value in set. |
| Length | Total Number of data values. |
| Filename | File from which the dataset was loaded. |
| Graphs | List of graph windows containing this dataset. |
Elements in the list can be selected by clicking the elements with the left mouse button, the selection can be extended using the shift key and the left mouse button and single elements added/removed using the Control key and the left mouse button.
(*): Column values can be changed by pressing the
edit mode button and clicking on the cell to change the contents. Pressing the
while in edit mode will leave the edit mode.
(¹): Columns are hidden by default, but can be viewed using the
menu on the top right hand of the table.
Note
Datasets with mixed Labelled and Numerical data values will have a colored background (by default light Orange) Datasets with non dated x-values data values will have a colored background (by default Purple).
Tip
The columns can be sorted by clicking on the column headers, a second and successive clicks will reverse the order of the sort.
The Data Sets window can be used to manipulate the data sets in several ways:
- A double click with the left mouse button will open a new graph with the selected data displayed.
- Pressing Enter on the keyboard will open a new graph with the selected data displayed.
- A right mouse click on the data sets list will display a popup menu with a set of actions which change depending on the current selected datasets and the element under the mouse pointer.
- Single data sets can be displayed in the Statistics window by clicking with the right mouse button directly on the data element and selecting the 'Statistics' option from the menu (N.B. this action does not use the- current selection but the nearest to the mouse cursor - even if it is past the end of the table).
- Selected data sets can be displayed on any Graph window by dragging the elements with the left mouse button pressed onto the graph window to be used and releasing the button.
- Selected data sets can be deleted - after confirmation - by dragging the elements with the left mouse button pressed and releasing the button anywhere but over a graph window or the calculator.
- Selected data sets can be deleted - after confirmation - by pressing the DELETE key.
- Selected data sets can be inserted into the calculator formula - by dragging the elements with the left mouse button pressed onto the Calculator window and releasing the button.
Tool Bar

 |
Hide tool bar Remove the tool bar for this window. (N.B. The tool bar can be restored in the window menu). |
Tip
The tool bar can be placed on any of the edges of the graph window by dragging it to that edge or pressing the right mouse button on any blank space and selecting an edge on the popup menu.
Data Sets popup Menu
The data sets menu can display the following entries:
| Icon | Action |
|---|---|
 |
New Graph Create a new graph and display the selected datasets. |
|
New Individual Graphs Create a new graph for each of the selected datasets. |
 |
Statistics Open the 'Statistics' window for this dataset. |
 |
Sort Chronologically Sort this dataset (and any associated datasets) into chronological order (apply to dated datasets only). |
 |
Adjust dates Change the format or adjust the dates for this dataset. |
|
Convert to SECONDS Change the format for the X-axis of this dataset to SECONDS. |
 |
Set/Edit Labels Change the set of associated label values for a dataset. |
 |
Delete dataset Ask confirmation to delete this dataset. |
 |
Fast Fourier Transform Create the Spectrum Phase and Spectrum Modulus datasets based on frequency. |
|
Function Use the calculator function to generate new datasets by applying the function. (The remaining menu entries depend on the number and order of the selected datasets.) |
Tip
The available functions can vary depending on which groups of functions are active and the order they are selected.
Data Sets window Menu

Tip
The title bar contains a count of the number of data sets in memory.
Filtering
PrestoPlot implements a filtering mechanism on the dataset table to reduce the contents.
Any table column which displays a (*) just before the title for the column will allow filtering on the contents of the column.
The filtering will hide all the rows in the table which do not correspond to the current filter.
If a filter is active on a column, then the label will display the text of the filter between the ()'s without the *
There are different forms of filters available:
- Pre-defined filters for quick access.
- Custom filters which allow three special characters, '
*' which replaces any set of characters, '?' which replaces exactly one character and '|' which allows to apply many filters at the same time.
e.g. *ABC will display only the lines containing any text with ABC at the end in this column.
e.g. *A|*B will display the lines containing any text with A or with B at the end in this column.
For some columns, filters for all the elements are available by right-clicking on the head of the column, if the number of different elements is less than 20.
Multiple columns can be filtered at the same time and only the rows which correspond to all of the active filters will be displayed.
The column filter menus allow resetting the current filer for a column or resetting all filters on the table.
