Principle component analysis

The experiment went as follows: 6 samples were given 18 attributes following a sensory evaluation test.
these have been put into s selection of charts - the first has the Plot of loadiing and has the 18 attributes dotted across the chart, X axis is PC1 and Y axis is PC2. a second chart has the same but has the 6 samples dotted across the chart. after that i have a new selection of chart but they have X axis is PC2 and Y is PC3, again with the figures dotted on the chart.
I have been asked to interpret these figures but i dont know how. PLease can you help?

<br><br>Principle Component Analysis
<br><br>
<br><br>The multivariate statistical method of Principle Component Analysis is a very useful tool for reducing the number of variables in a data set and for obtaining useful two-dimensional views of a multi-dimensional data set. For your problem, the data matrix consisting of eighteen elements can be considered to exist in eighteen-dimensional space (since this would be the number of dimensions required to simultaneously plot all of the variables against one another). ...

Solution Summary

The solution discusses the experiment went as follows: 6 samples were given 18 attributes following a sensory evaluation test. These have been put into s selection of charts - the first has the Plot of loadiing and has the 18 attributes dotted across the chart, X axis is PC1 and Y axis is PC2. a second chart has the same but has the 6 samples dotted across the chart. after that i have a new selection of chart but they have X axis is PC2 and Y is PC3, again with the figures dotted on the chart.
