Dear Sir or Madam, I've just read your message in the PSPP list. One problem is that your data are discrete with a small number of categories, but histograms are most useful for continuous data. For discrete data with a small number of categories, a bar chart is more appropriate. I attached yo

Hi, I want to graph a simple frequency distribution of ta variable called soctrust from a national sample. I compare the histogram from a FREQUENCIES command with a diagramme from a GRAPH command. The variable can have integer values from 0 to 10. FREQUENCIES /VARIABLES= soctrust /FO

Hi, your data only has discrete values 1,2,3 … 10. Only the histogram bins which range e.g. from [2.333, 3) (2. <= x < 3) are empty. This is correct as there are really no cases which have values in that range. The histogram x-axis labeling is now a continuous range. For your specific prob

Hi, The attached pdf file shows the bizarre translation of DV var levels into the histogram graph. All the 10 continuous levels of the dependent variable soctrust are occupied, but the histogram shows unoccupied classes. The diagram is misleading to me. I then repeated the example with three three
