Display menu

The Display menu contains commands that let you load, create, close and print one and two-dimensional spectra (displays).

The basic set of displays that are used during acquisition should be created by the MNG application. You can open them for viewing, but you can’t delete them.

Therefore, if you close such display or even the MDI application, it has no effect on the displays and they remain in the memory. However, using the MDI you can create some temporary displays during measurement that lasts until you close them.

3.1.1. Open

The command opens a new display.

It brings up ‘Open Display‘ dialog that contains a list of one and dimensional displays created by the MNG (see ‘MNG Acquisition Displays‘). A two-dimensional display can be opened either as a map (‘map view‘) or in isometric projection (‘isometric view‘). To choose the view select appropriate button.

To open a display click on the corresponding item in the list and then press

‘OK’ button, or double-click on the item. A new display window will be created and shown as the active window. You can close and open it again without losing the data.

Moreover, you are allowed to close the MDI application without affecting the data. In addition, you can open more instances of the same spectrum. This means that a spectrum is kept in the memory until you delete it from MNG. This happens when

Figure 3.1.1.1 The ‘Open Display‘ dialog box.

you load new data or use ‘Delete’ command in the ‘MNG Acquisition Displays’

dialog.

3.1.2. Open all

The command opens all available displays.

The window of the last opened display becomes active. The windows should be created by ‘MNG Acquisition Displays‘ dialog.

3.1.3. Open all on start

The command enables or disables automatic opening of all displays each time the acquisition is started or a new data are loaded.

3.1.4. Read

The command reads display from a user-selected file and shows it in a separate window.

This is an inverse of the ‘Write’ command. The file name and format should be entered in the dialog box that is automatically opened. Usually, the command is used to read previously stored display that had been created by the MDI application. See also ‘Display Read’ command.

3.1.5. Write

The command writes data of the active display in ASCII format (extension .ASC).

For each count in the spectra one line is written that contains x(y) channel number and channel content, separated by a blank character. In addition, the GANAAS format with extension .SPE is supported. It is a special ASCII format with a short header, which can be used to evaluate spectra with the GANAAS software from the I.A.E.A.

The command starts ‘Save As’ dialog that let you select file name and format.

To save all displays you should use ‘MNG Data Save’ command. Note this does not save displays that were created by ‘Display Create’ command. Therefore, the only way to save such displays is to apply ‘Write’ command.

3.1.6. Create single

The command creates one-dimensional auxiliary spectrum.

The spectrum can’t be used to collect data into. Moreover, it lasts until the MDI is active and can’t be recovered after that. One should use the ‘Display … Write’

command to save it.

The data are stored as 32-bit unsigned integers and initially all channels contain zero counts. To store data into the display you can use ‘Tools Compose’

command or do it from the Control application.

The command brings up the ‘Create Single’ dialog. There you can define the basic display feature.

The ‘Name’ defines display name; the ‘Title’ sets title on its axes; the

‘Resolution’ is an integer that determines the number of channels. The ‘Minimum’ and

‘Maximum’ are real numbers that are used to calibrate x-axis (linear transformation).

They correspond to the first (ch=0) and last (ch=Resolution-1) channel, respectively.

Therefore, if you want to display channels on the axis then set Minimum=0 and Maximum=Resolution-1.

3.1.7. Create map

The command creates two-dimensional auxiliary spectrum.

The spectrum can’t be used to collect data. Moreover, it lasts until the MDI is active and can’t be recovered after that. One should use the ‘Display … Write’

command to save it.

The data are stored as 32-bit unsigned integers and initially all channels contain zero counts. To store data into the display you can use ‘Tools Compose’

command or do it from the Control application.

The command brings up the ‘Create Map’ dialog. There you can define the basic display feature. The ‘Name’ defines display name. For each axis, you can define the following items: the ‘Title’ sets title on its axes; the ‘Resolution’ determines the number of channels. The ‘Minimum’ and ‘Maximum’ are real numbers that are used to calibrate x/y-axis (linear transformation). They correspond to the first (ch=0) and last (ch=Resolution-1) channel, respectively. Therefore, if you want to display channels on particular axis then set Minimum=0 and Maximum=Resolution-1.

3.1.8. Print

The command prints one or more histograms to the printer.

It is not intended to print final work. Rather, use it for draft, multi-histogram printouts.

The command brings up ‘Print’ dialog that let you customize printout. The dialog features an automatic histogram placement. To enable this you should check

dimensional, equal-sized areas called ‘zones’. The number of zones in the horizontal and vertical direction can be selected by ‘Paper zones-Vert.’ and ‘Paper zones-Horiz.’

lists, respectively.

To place a histogram in a zone you should select it from the upper list of histograms and then apply ‘Add’ command. In that case, the selected histogram appears on the bottom list and it is indicated by the shadow area on the page layout.

To select all histograms apply ‘Add All’. To deselect, that is remove from printout, one or all histograms use ‘Remove’ and ‘Remove All’ respectively. The zones are filled by the histograms automatically and in the successive order.

The position of a histogram inside a zone is the same for each zone. This is set by the ‘Left’, ‘Right’, ‘Top’ and ‘Bottom’ zone margins that are defined in the units of 1/100th of the vertical and horizontal zone size.

One can define the histogram position manually. To do this the ‘Paper zones - Enable’ box should be unchecked. In that case, you can use the four edit-controls bellow the bottom list. Starting from the leftmost, they define page, left and top corner position, height and width, respectively.

The group of checkbox called ‘Info’ let you to print a few additional information: the ‘Date’- date of printing; the ‘FileName’- name of file that contains printed histograms; the ‘Title’- title for each histogram; ‘PageNum’ - number of each page; ‘Frame’- rectangular border.

The size of drawing object may be adjusted by ‘Thickness factor-Vert’ and

‘Thicknes facot-Horiz.’. You can also use ‘Options Axis View’ and ‘Options Single View’ commands to adjust thickness of lines and size of symbols. To adjust font size use ‘Font factor – Width’, ‘Font factor – Height’ and ‘Font factor – Weight’.

3.1.9. Setup printer

The command setups your printer.

A standard Windows dialog box is opened that let you set properties of you printer.

3.1.10. Exit

The command closes the MDI application and frees its resources from memory.

The acquisition data are not lost, because they are allocated by the MNG application. Therefore, you can retrieve them by starting again the MDI application.

Any resources that are not allocated by MNG are lost. Such are: any display produced from a display defined by MNG (projection) and any display created by

‘Display Create’ command.
