2.2.5. Using technology to create diagrams

Excel
Diagrams can easily be added in Excel. You can either start from scratch, or first select the data you want to see and then go to the Insert ribbon and select the chart you like to use.

When a chart has been selected you also get the Cart ribbon with plenty of options to adjust the chart.
Excel uses the term column chart for bar-charts and will require some work to create a histogram.

A video showing a few examples is shown below.


SPSS
In SPSS there are a few different ways to create graphs:
  • Graphs – Chart Builder
    This option lets you choose from various graphs and select the variables you want to use. It shows a visual draft of the chart your building.
  • Graphs – Graphboard Template Chooser
    This option lets you choose the variable(s) you want a graph of and then suggests a few different charts. The disadvantage of this option is that the chart created cannot be changed much once it is created.
  • Graphs – Legacy Dialogs
    This option you simply click on the chart you want and then fill out the options for each chart.
It is also possible to create a graph from a table in the output. Double click on the table, select the data you want a graph of, right-click and select the graph you want.

Many other options in the analysis menu each have an option to also immediately add a chart to the output.

Editing a chart in SPSS is done simply by double clicking on the chart. This opens the chart editor (unless you used the graphboard template chooser, then it will open up the graphboard editor which has far less functionality).

A video showing the above mentioned different methods is shown below


TI-83

Unfortunately the graphing capabilities of this graphical calculator are a bit limited and focused on graphing mathematical functions, not so much on graphing data.

By setting up two lists (see tables section) it is possible to get a line graph and a bar chart (but with the columns connected to each other). This can be done by using [2nd] [STAT PLOT].

A video showing an example of this can be found below.
