A tag cloud is a representation of words indicating the importance of the words by manipulating the visual properties. Here we use the distribution of font size, transparency and boldness of the font.
The user can change the following view properties on the fly:
- Minimal and maximal font size
- The distribution of the font size (linear, logarithm or exponential)
- The font name
- The amount of bold terms
- The transparency of the labels
- Zooming
Color of term:
To improve the variety of the tag cloud the colors of the terms are arranged. There are two possibilities. The user can create its own distribution method by adding a color to the rows, using the color appender.
If there were no colors added to the rows, the color will be arranged using the type of the first term. The so preselected colors can afterwards be changed on the fly.
HiLiting:
The terms may be selected by dragging a rectangle with the mouse over the points or by clicking on points. The selected terms may be hilited by either right-click to get the context menu or via the hilite menu in the menu bar.
Important: If a term was found in more than one row, hiliting this term will cause all rows to be hilited, which contains this term. On the other hand, for hiliting a term it is sufficient that one of its representing rows was hilited.
