Plotting
Generating plots generally involves selecting suitable icons (often as x's or y's) and then choosing a suitable plot command.
Plots may be moved by dragging with the mouse.
- Bar Charts
- count the number of cases in a a (usually) non-numeric variable.
- Boxplots
- are produced by the same method as dotplots but add
information such as the 25th and 75th percentiles, outliers, and
the median.
- Dotplots
- involve selecting numeric data as y and categorical data as x.
- Histograms
- display numeric data in bars. Bar width can be adjusted by
choosing Plot Scale from the hyperview menu (sidewise
triangle) to the left of the title of the histogram window.
to the number of cases
- Lineplots
- require the selection of one numeric variable and plot this
against the case number (which starts at 1.)
- Normal Prob Plots
- plots the actual sorted values of the selected variable
against a hypothetical normal distribution determined by the NScores function.
- Piecharts
- like barcharts count up the number of cases.
- Rotating Plots
- require the selection of 3 numeric variables. They may
be set into continued motion by releasing the mouse while dragging.
- Scatterplots
- reuire the selection of numeric x and y variables. The
hyperview menu includes the possibility of adding a least squares
line of regression.
