Titles and descriptions
The default titles for new visualizations varies with the visualization type, and sometimes also with the configuration of the visualization. When the 'Auto Title' option is used, the title of a visualization changes when you configure the visualization differently. If you want a different title, you can specify it in the visualization properties.

In the installed client, you can show or hide the entire title bar by right-clicking the visualization and selecting , or you can use the visualization properties for both the installed and the web client. Under Title bar, you can choose if you want to show or hide the visualization title and warnings. You can hide the whole title bar by removing the Title bar card from the visualization properties panel.
If you want the titles of pages and visualizations, or the visualization descriptions, to change with the selections done on the visualization axes, you can define the title or description to use the built-in "axis visualization properties" or by setting up custom document properties to be used in the title or description. Document properties can, in turn, be controlled via property controls in the text area. See Working with dynamic titles and descriptions for more details about how to add dynamic content.
The default scatter plot title
The default title of a new scatter plot is constructed by the display names used on the axes of the visualization:

When the axes are changed, then the title of the visualization is automatically updated:

Setting up a custom dynamic bar chart title

However, you might want to use another dynamic title instead, which contains the display names used on the axes of the bar chart as well as the categorization on the color axis. Right-click on the visualization and select Properties from the pop-up menu. On the General page, click Edit.

Here, you can select the properties of interest and insert them into the Title expression field. You can also type additional information in plain text. For example, the following expression includes the display names for the X- and Y-axes and also the color axis:
${Axis.Y.DisplayName} per ${Axis.X.DisplayName}, split by
${Axis.Color.DisplayName}
This would result in the following title, using the same visualization setup as above:

Dynamic description updated using a property control
MeasureColumnSelection has been used to set what is
shown on the Value axis of a bar chart. A
property control in the text area allows you
to change the value of the property:

The expressions used in this visualization were:
- On the Value axis:
Sum($esc(${MeasureColumnSelection})) - Title expression:
${MeasureColumnSelection} per year - Description expression:
This visualization shows the ${MeasureColumnSelection} per year.

- Working with dynamic titles and descriptions
Titles and descriptions of visualizations can be configured so that parts of the text are showing values that are updated somewhere else in the document. You can let the title or description of a visualization contain a value specified using either the built-in "axis visualization properties" or custom document properties.
