Graph time series as bars

Note: This is a beta feature. Time series panel is going to replace the Graph panel in the future releases.

This section explains how to use Time series field options to visualize time series data as bars and illustrates what the options do.

Create the panel

Add a panel. Select the Time series visualization.
In the Panel editor, click the Field tab.
In Style, click Bars.

Style the bars

Use the following field settings to refine your visualization.

For more information about applying these options, refer to:

Some field options will not affect the visualization until you click outside of the field option box you are editing or press Enter.

Bar alignment

Set the position of the bar relative to a data point. In the examples below, Show points is set to Always to make it easier to see the difference this setting makes. The points do not change; the bars change in relationship to the points.

Before

The bar is drawn before the point. The point is placed on the trailing corner of the bar.

Center

The bar is drawn around the point. The point is placed in the center of the bar. This is the default.

After

The bar is drawn after the point. The point is placed on the leading corner of the bar.

Line width

Set the thickness of the lines bar outlines, from 0 to 10 pixels. Fill opacity is set to 10 in the examples below.

Line thickness set to 1:

Line thickness set to 7:

Fill opacity

Set the opacity of the bar fill, from 0 to 100 percent. In the examples below, the Line width is set to 1.

Fill opacity set to 20:

Fill opacity set to 95:

Gradient mode

Set the mode of the gradient fill. Fill gradient is based on the line color. To change the color, use the standard color scheme field option.

Gradient appearance is influenced by the Fill opacity setting. In the screenshots below, Fill opacity is set to 50.

None

No gradient fill. This is the default setting.

Opacity

Transparency of the gradient is calculated based on the values on the y-axis. Opacity of the fill is increasing with the values on the Y-axis.

Hue

Gradient color is generated based on the hue of the line color.

Show points

Choose when the points should be shown on the graph

Auto

Grafana automatically decides whether or not to show the points depending on the density of the data. If the density is low, then points are shown.

Always

Show the points no matter how dense the data set is. This example uses a Line width of 1. If the line width is thicker than the point size, then the line obscures the points.
