The table below lists the settings for the Bar chart, Stacked bar chart, and Date Histogram type graphs located on the Appearance tab.

Description of parameters

Setting	Description
Name	Name of the widget.
Description	Description of the widget.
Tenant	The tenant for which data is displayed in the widget. You can select multiple tenants. By default, data is displayed for tenants selected in layout settings.
Time period	Period for which data is displayed in the widget. The default is As layout, meaning that data is displayed for the period selected for the layout. You can also specify a period for the widget in one of the following ways: Select the exact start and end date and time of the period in the calendar and click Apply. Select a period relative to the present time in the Relative period list. Specify a value manually: select an exact date and time or a relative period, or a combination of both. For details, see the Configuring a period subsection below.
Format	Data display format: Absolute values or Relative values, %. The setting is available for a Stacked Bar chart. If you select the Absolute values format, the heights of the bars correspond to the sum of the values of the measured indicator. If you select the Relative values, % format, all bars have the same height of 100%, and the relative heights of colored zones on the bars correspond to the ratios of indicator values. By default, Absolute values is selected.
Timeline view	Time data display format: Bar chart or Line chart. This setting is available for charts of the Date Histogram type. When you select the Bar chart format, the data is displayed as vertical bars by default. If the SQL query contains an additional field with the `category` alias, the chart becomes a stacked bar chart, that is, each bar is divided into stripes in accordance with the values of this field. When you select the Line chart format, the data is displayed as one or more (depending on the query) polylines drawn through points on the time axis. The Bar chart format is selected by default.

If not set manually, gradient thresholds are calculated automatically from the data. If there is no data between the specified thresholds, the gradient is not applied. Instead, two colors are used: one for values below the lower threshold, and the other for values above the upper threshold. Gradient fill is not applied to stacked bar charts. In this case, colors are assigned automatically.
Horizontal	Makes the histogram horizontal instead of vertical. When this setting is enabled, all available information is fitted into the configured widget size. If the amount of data is great, you can enlarge the widget to better fit the data.
Show total	Shows sums total of the values.
Show legend	Displays a legend for the analytics. The toggle switch is turned on by default.
Show nulls in legend	Displays parameters with a null value in the legend for analytics. The toggle switch is turned on by default. Null values are displayed only when the Show data for previous period setting is enabled and there is no data for the current period, but there was some data for the previous period.
Period segments length	Duration of the segments into which you want to divide the period. Available for graphs of the Date Histogram type.

Configuring a period

For graphs such as Pie chart, Counter, Table, Bar chart, Stacked bar chart, Date Histogram, you can configure the period for displaying data in the widget using the Period setting. By default, the data display period of the widget is the same as the data display period of the dashboard.

To configure the data display period, do one of the following:

If necessary, change the date and time in the Time period setting in one of the following ways:
- If you want to specify an exact date, in the calendar on the left, select the start and end date of the period and click Apply.
  You can select a date up to and including the current date. The date and time format depends on your browser settings. If the Date from or Date to field has a value and you have not edited the time value manually, when you select a date in the calendar, the Date from field is automatically populated with 00:00:00.000, and the Date to field with 23:59:59.999. If you have manually deleted the value in the Date from or Date to field, when you select a date in the calendar, the field is automatically populated with the current time. After you select a value in one of the fields, the focus switches to the other field. If your Date to is earlier than your Date from, this earlier value is automatically inserted into the Date from field.
- If you want to specify a relative period, select one of the available periods in the Relative period list on the right.
  The period is calculated relative to the current time.
- If you want to specify a custom period, edit the value of the Date from and Date to fields.
  You can enter an exact date and time in the DD.MM.YYYY HH:mm:ss.SSS format for the Russian localization and YYYY-MM-DD HH:mm:ss.SSS for the English localization or a period relative to the current time as a formula. You can also combine these methods if necessary. If you do not specify milliseconds when entering the exact date, 000 is substituted automatically. If you have edited the time in the Date from or Date to fields, picking a date in the calendar does not change the time component.
  
  In the relative period formulas, you can use the now parameter for the current date and time and the interval parameterization language: + (only in the Date to field), -, / (rounding to the nearest), as well as time units: y (year), M (month), w (week), d (day), h (hour), m (minute), s (second). For example, you can specify the period now-5d to get data for the last five days, or now/w to get data from the beginning of the first day of the current week (00:00:00:000 UTC) to the current time (now).
  
  The Date from field is required, and its value cannot exceed the value of the Date from field, and also cannot be earlier than 1970-01-01 (if specifying an exact date or a relative period). The Date to cannot be earlier than the Date from. If you do not specify a value in the Date from field, now is specified automatically.
KUMA stores time values in UTC, but in the user interface time is converted to the time zone of your browser. This is relevant to the relative periods: Today, Yesterday, This week, and This month. For example, if the time zone in your browser is UTC+3, and you select Today as the data display period, data will be displayed for the period from 03:00:00.000 until now, not from 00:00:00.000 until now.

If you want to take your time zone into account when selecting a relative data display period, such as Today, Yesterday, This week, or This month, you need to manually add a time offset in the Date from and Date to fields (if a value other than now is specified) by adding or subtracting the correct number of hours. For example, if your browser's time zone is UTC+3 and you want to display data for Yesterday, you need to change Date from to now-1d/d-3h and Date to to now/d-3h. If you want to display data for the Today period, you only need to change the value in the Date from field to now/d-3h.

If you need results up to 23:59:59:999 UTC of yesterday, you can use an SQL query with a filter by Timestamp or specify an exact date and time.

The bounds of the period are inclusive: for example, for the Today time range, events are displayed from the beginning (00:00:00:000 UTC) of the current day to the current time (now) inclusive, and for the Yesterday period, events are displayed from the beginning (00:00:00:000 UTC) of the previous day to 00:00:00:000 UTC of the current day. You can view the date and time of the last data update and the exact period for which the data is displayed by hovering over the period icon in the widget.

If the Show data for previous period setting is enabled for the widget, and the widget is displaying data for a relative period, the tooltip also displays the previous period. The previous period is calculated relative to the current period as start and end values of the current period minus the duration of the current period. For example, if data is updated daily and displayed for a month, but only the first 10 days of the month have passed, the previous period is taken to be the last 10 days of the previous month.
If you want the widget to display data for the period selected for the layout, click the Reset button. Changing the displayed period on the layout also changes the period displayed in the widget.
