This mode allows, for example, data from different archival units to be compared.
## Chart Type "By categories" Since the default chart type is "By categories," let’s examine it first. By clicking on the dropdown tab "Category," you will open a list of categories that can be used to view the data in the form of charts.
### Unit Title If you select the first category, "Unit Title," the information will be filtered by archival unit titles. This chart compares the number of messages in the selected archival units over a specific period of time.
Let’s look at what the other categories in the "By categories" list display: ### Unit Type Сompares the number of published messages in chats and channels over a specific period of time.
### Thematic Collection Compares the number of messages in different thematic collections.
### Post Type Compares the number of posts, comments, technical messages, and dates across all archival units available to the user.
### Hashtags Compares which hashtags and their frequencies are mentioned over a specific period of time in the selected archival units.
### Mentions Displays the number of messages that contain mentions using "@".
### URL Shows the number and list of domain names mentioned in the selected archival units.
### Has images Displays the number of messages with and without images in the selected units. The same principle applies to the categories "Has audio" and "Has video."
### Email Displays which email addresses are mentioned within the selected period.
### Author Shows the number of messages created by a specific author.
### Language Displays the number of messages written in Ukrainian, Russian, English, etc.
### Country Shows the frequency of mentions of a specific country in the archival material.
The "Categories" panel is similar to the "[Filters](/tg-research/filters.md)" panel. However, they do not duplicate functions but rather complement each other. They can be combined to narrow down the search, make comparisons, or visualize the search results across multiple parameters simultaneously. For example, to reduce the number of archival units for comparison, select "Unit Title" in the "By categories" charts, and choose several archival units in the "Unit Title" filter. As shown in the screenshot, now only two chats are displayed instead of all.
Just like in [text](/tg-research/viewing-mode/text.md) and [table](/tg-research/viewing-mode/table.md) formats, you can view the results of [text searches](/tg-research/text-search.md) in the chart format. We can select the "Unit Title" category and enter the word `Україна` (Ukraine) in the search field. As a result, the chart will display how many times and when the word `Україна` (Ukraine) was used in the selected archival units.
## Chart Type "By custom query" With this feature, you can create custom text queries that search across all selected archival units, and then add the results layer by layer to the chart using the button. To obtain more relevant search results, entering a phrase with the "+" symbol will make the search more effective. If you enclose your query in quotation marks (" "), the system will find only exact matches that are fully identical to your request.
If required, you can separate the combined charts into individual charts. To do this, uncheck the box. As you can see, the archival units are no longer combined into one chart but are displayed in separate individual charts.
## Additional features **Data view** - shows the numerical data on which the chart is based.
The "**Switch to Bar Chart**" button allows you to change the chart type from a line chart to a bar chart.
**Restore** – restores the previous chart settings **Save as Image** – allows you to download the chart image in .png format. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://blog.telegram.lvivcenter.org/tg-research/viewing-mode/charts-and-graphs.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
