| Grafické zobrazení umožňuje vizualizovat informace představené v předchozím oddílu (absolutní a relativní frekvence položek s jejich konfidenčními intervaly) do podoby dvou typů grafů: horizontálního **sloupcového grafu** a grafu typu "**word cloud**". | The graphical display allows you to visualize the information presented in the previous section (absolute and relative frequencies of items with their confidence intervals) in the form of two types of graphs: either a horizontal **bar chart** or a "**word cloud**" graph. |

| Ve výchozím nastavení se zobrazuje sloupcový graf s hodnotami relativních četností včetně konfidenčních intervalů na hladině 95 %. | By default, a bar chart with relative frequencies including 95% confidence intervals is displayed. |
| |
| Po rozkliknutí voleb nad grafem pomocí **(+)** je možné vlastnosti grafu upravit. Místo hodnot relativní četnosti lze zobrazit četnosti absolutní, dále lze omezit počet položek v grafu, seřadit položky podle abecedy namísto frekvenčního třídění a také exportovat graf jako obrázek. | By clicking on the options above the graph using **(+)** you can modify the properties of the graph. You can display absolute frequencies instead of relative frequency values, limit the number of items in the graph, sort items alphabetically instead of frequency sorting, and export the graph as an image. |
| |
| Nakonec je možné graf přepnout do podoby grafu typu "word cloud", který zobrazuje skupinu zkoumaných položek (v našem příkladů tvarů slov) ve velikostech poměrně odpovídající jejich četnostem. Pro tento typ grafu je v uživatelském nastavení relevantní pouze možnost exportu grafu a omezení počtu položek v grafu. | Finally, the graph can be switched to a "word cloud," which displays a group of examined items (in our example, word forms) in sizes corresponding relatively to their frequencies. For this type of graph, only the option to export the graph and limit the number of items in the graph are relevant in the user settings. |

| Afterwards, it is necessary to select whether frequency distribution should be calculated regardless of the letter case. Selection of the option [[wp>Case_sensitivity|case-insensitive]] causes that all of the items are interpreted as having lower case, regardless of what type of case they actually have in the corpus. | Afterwards, it is necessary to select whether frequency distribution should be calculated regardless of the letter case.

| In case of custom settings of frequency distribution, we do not need to restrict ourselves to KWIC only (unlike when working with quick selection). It can be calculated from any context position to the right or left from the wanted word. The item //position// in the form enables us to select not only positions from the left (the preceding) context (6L-1L), but also KWIC itself and positions to the right (the following) context (1R-6R). The numbering of the positions (according to both current and older notation) is summed up in the following table: | In case of custom settings of frequency distribution, we do not need to restrict ourselves to KWIC only (unlike when working with quick selection).

| After clicking on **Make frequency list**, a table of results is displayed summarizing the number of occurrences of the adjectives in three selected text type groups (fiction, non-fiction and journalistic texts), sorted by frequency. This default setting can be changed: you can re-sort the table by [[en:pojmy:ipm|ipm]], switch the orientation of rows and columns or opt for a list of attribute pairs. If you are an advanced user, you can also try to sort the rows based on three criteria (attribute value, the total of absolute/relative frequency in a row or in a column), set the confidence interval (CI) or temper with the color mapping (for further information, see the help question mark next to the **Color mapping** choice). If you choose the relative frequency display, you can also look at a graph with confidence intervals by clicking on the chart icon next to each variable. | After clicking on **Make frequency list**, a table of results is displayed summarizing the number of occurrences of the adjectives in three selected text type groups (fiction, non-fiction and journalistic texts), sorted by frequency.
