# 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
|
|
|
|
1. [Add a panel]({{< relref "../../add-a-panel.md" >}}). Select the [Time series]({{< relref "_index.md" >}}) visualization.
|
|
1. In the [Panel editor]({{< relref "../../panel-editor.md" >}}), click the **Field** tab.
|
|
1. 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:
|
|
|
|
- [Configure all fields]({{< relref "../../field-options/configure-all-fields.md" >}})
|
|
- [Configure specific fields]({{< relref "../../field-options/configure-specific-fields.md" >}})
|
|
|
|
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]({{< relref "../../field-options/standard-field-options.md#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.
|
|
|
|
##### Point size
|
|
|
|
Set the size of the points, from 1 to 40 pixels in diameter.
|
|
|
|
Point size set to 6:
|
|
|
|

|
|
|
|
Point size set to 20:
|
|
|
|

|
|
|
|
#### Never
|
|
|
|
Never show the points.
|
|
|
