• 9 words of 3 characters length ;
• 19 words of 4 characters length ;
• and so on , up to 1 word of 15 characters length;

• 5 words of 3 characters length ;
• 4 words of 4 characters length ;
• 2 words of 5 characters length ;
• and so on.

The term "length" for words and wordforms stands for number of characters. For phrases, length is number of words.

Every new chart appears in new tab so you can switch between multiple charts in right pane. Unnecessary charts can be closed either by "Close" button or context menu command over the tab caption.

All charts are interactive and allows sizing and moving . For large numbers of results, chart window becomes overloaded with data and it is impossible to get valuable picture in original scale. There are two ways of zooming and dragging. First way is chart toolbar . Toolbar buttons provides navigation to four directions, zooming in and out, and getting back to original view. Second way is mouse operations over the chart. When you click left mouse button and keep it pressed, you can select the rectangular frame which becomes the zoomed area . Holding right mouse button pressed, you can drag chart to any direction.
