We got a question from Lucinda, who wants to publish her results, but has a problem with the resolution of the output. She asked us:
“I have made some interactive line graphs that have been submitted to a scientific journal for publication. The journal editor says that the resolution of the graphs is not high enough to print. Do you know how I can increase the resolution of the graphs?”
You can export your graphs into different file formats:
1. Rightclick your chart (in the Output window)
2. Choose Eport, which gives you the following pop-up screen:
3. Set the file type to Postscript (EPS). This is the file format most graphical guys (DTP-ers) can handle this format without a problem. Set the other options according to your wishes, and press OK.
If you have any other questions, please don’t hesitate to contact us.

This Friday we got a question from Els, who has a problem with making her stacked bar graphs look good:
“As a trainee I am now analysing the results of a customer satisfactory investigation. Many people advised me to use SPSS, so I did.
Most of the questionnaire questions are built the same way (very dissatisfied, dissatisfied, satisfied, very satisfied).
The report will be devised in subjects (price, quality, reaction speed,etc). Each subject contains around 5 questions.
For each subject I made a horizontal graph in which all 5 questions regarding that subject are being displayed. This way I will analyze around 5 questions in each graph, as in this example.
The stacked graphs I made myself are horizontal, 100% stacked, so the bar fills the entire graph horizontally (like in the example). So far, so good, it looks great!
Then the problem: Inside the bars I would like to show the exact percentage over that question.(like in the example).
The problem is, that these figures are incorrect. Now I see the percentage concerning the entire graph, all the questions together, in stead of per question.
Can you tell me what I have to do to change the figures inside the bars from a percentage over the entire graph to a percentage over the bar?”
To solve the problem we will describe step by step how to make a 100% stacked bar chart, and how to get the exact percentages into it. First select Tables > Tables of frequencies.
Now drag the five questions you want to make graphs for to Frequencies for. Click on statistics and choose percent. Click ok, and you are back at the â€˜tables of frequenciesâ€™ screen. By clicking ok again you will get a table.
Select the table by double-clicking, then click the right-mouse button and select create graph > bar. Now you will get the following screen (click on the picture to show the screen shot in full size):
Click at the red marked button in the picture above. In this screen you can change the option cluster after â€˜colorâ€™ into stack. Go back to the graph and click on the button Horizontale orientation.
After this you have to double click on one of the bars. A new screen will open. In this screen you can click on values in bar labels. Now you can choose the location of the percent value. Now click on inside base and then click ok. Then you will have 100% stacked bars, with the exact percentage on that question inside.

The look and feel of your tables are a critical part of providing clear, concise, and meaningful results. For example, if your table is difficult to read, the information contained within that table may not be easily understood.
In this log we will introduce the tablelook option in SPSS.
Double-click the table.
From the menus choose: Format > Tablelook
The TableLooks dialog box lists a variety of predefined styles. Select a style from the list to preview it in the Sample window to the right.
You can use a style as is, or you can edit an existing style to better suit your needs. To use an existing style, select one and click OK.
Although you can change the format of a table after it has been created, it may be more efficient to change the default TableLook so that you do not have to change the format every time you create a table. To change the default TableLook style for your pivot tables, from the menus choose:
Edit > Options> Pivot Tables
Select the TableLook style that you want to use for all new tables. Click OK to save your settings and close the dialog box. All tables that you create after changing the default TableLook automatically conform to the new formatting rules.
