133 | Pie charts can be used when you need to represent a value as part of a whole. It is commonly used to represent percentages, |
---|
134 | relative magnitudes or relative frequencies. If your intent is to compare a particular value (slice) against the whole of |
---|
135 | the Pie chart, then it can be quite effective. If however you want to compare two seperate segments, then it can get |
---|
136 | more difficult. If this is the case, you may want to consider a bar chart for example. |
---|
137 | </p> |
---|
138 | |
---|
139 | <p> |
---|
140 | The colours can be customised, as can the borders (using the same color as the background and a line width of |
---|
141 | about 5 gives the effect of segment separation. The chart can also have a drop shadow if you want one, but this shouldn't |
---|
142 | be used in conjunction with segment seperation. |
