How to explore data using graphs
An example for you to look at
Here is a simple
example of data exploration that you can download (right-click and

powerful graph plotting features. These enable you to quickly plot
different columns in a data table against one another using whatever
type of chart or graph is most appropriate - bar chart, pie chart,
x-y plot, etc. Unlike the Excel graph plotting wizard, ImagineIT
only needs to be told once where to find the data for adding titles
to graphs, labelling axes and labelling individual plots. Because
of this, you can generate several different graphs very quickly
and all of them will be automatically titled and labelled.
Not only is it easy to generate labelled
graphs in this way, it is also simple to change what is plotted
on either axis - just two clicks with the mouse will do this (see
below for details).
The result is a very straightforward
and fast method of exploring data graphically.
Typically, you will choose rows above
the main table of data to generate titles and labels, like those
labelled 'graph titles', 'axis labels' and 'plot labels' in the
example below (they will have a green background on screen - and
if this document has been printed in colour).
Note that the data must be arranged
in columns, not rows.
