Graph time series as lines

    1. . Select the Time series visualization.
    2. In the side pane, click Graph styles to expand it.
    3. In Style, click Lines.

    Use the following field settings to refine your visualization.

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

    Choose how Grafana interpolates the series line. The screenshots below show the same data displayed with different line interpolations.

    Linear

    Points are joined by straight lines.

    Smooth

    Points are joined by curved lines resulting in smooth transitions between points.

    Step before

    The line is displayed as steps between points. Points are rendered at the end of the step.

    Step after

    Line is displayed as steps between points. Points are rendered at the beginning of the step.

    Line width

    Set the thickness of the series line, from 0 to 10 pixels.

    Line thickness set to 1:

    Line thickness set to 7:

    Fill opacity

    Set the opacity of the series fill, from 0 to 100 percent.

    Fill opacity set to 20:

    Fill opacity set to 95:

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

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

    None

    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.

    Scheme

    In this mode the whole line will use a color gradient defined by your Color scheme option. There is more information on this option in .

    Line style

    Set the style of the line. To change the color, use the standard color scheme field option.

    Line style appearance is influenced by the Line width and Fill opacity settings. In the screenshots below, Line width is set to 3 and Fill opacity is set to 20.

    Solid

    Display solid line. This is the default setting.

    Dash

    Display a dashed line. When you choose this option, a list appears so that you can select the length and gap (length, gap) for the line dashes.

    Dash spacing set to 10, 10 (default):

    Dash spacing set to 10, 30:

    Dash spacing set to 40, 10:

    Dots

    Display dotted lines. When you choose this option, a list appears so that you can select the gap (length = 0, gap) for the dot spacing.

    Dot spacing set to 0, 10 (default):

    Dot spacing set to 0, 30:

    Connect null values

    Choose how null values (gaps in the data) are displayed on the graph. Null values can be connected to form a continuous line or, optionally, set a threshold above which gaps in the data should no longer be connected.

    Never

    Always

    Time series data points with gaps in the the data are always connected.

    Threshold

    A threshold can be set above which gaps in the data should no longer be connected. This can be useful when the connected gaps in the data are of a known size and/or within a known range and gaps outside this range should no longer be connected.

    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 and 50 data points. 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 4:

    Point size set to 10:

    Never

    Never show the points.

    Stack series

    For full instructions, refer to Graph stacked time series.

    For full instructions, refer to Change axis display.

    This option is only available as in the Overrides tab.

    Fill the area between two series. On the Overrides tab:

    1. Select the fields to fill below.
    2. Select the series that you want the fill to stop at.

    A-series filled below to B-series:

    Below are some line graph examples to give you ideas.

    Various line styles

    Fill below example

    This graph shows three series: Min, Max, and Value. The Min and Max series have Line width set to 0. Max has a Fill below to override set to Min, which fills the area between Max and Min with the Max line color.
