    Hourly Heatmap for Grafana

    Build Release Marketplace Downloads License Twitter

    A panel plugin for Grafana to visualize hourly heatmaps.

    An hourly heatmap aggregates data into buckets by day and hour to analyze activity or traffic during the day.



    The carpet-plot panel plugin is one of the most used plugins for Grafana. Unfortunately, it's no longer being actively maintained.

    Grafana 7.0 introduced a new plugin architecture based on React. Instead of migrating the original plugin from Angular, this is completely rewritten from scratch, using inspiration from the original plugin.


    This section lists the available configuration options for the JSON API data source.

    Panel options


    TimeName of the field to use for time. Defaults to the first time field.
    ValueName of the field to use for value. Defaults to the first number field.


    Show cell borderToggles a cell border to make it easier to distinguish cells with similar values
    Show tooltipToggles the tooltip. Due to the current tooltip implementation, this severely impacts performance and I recommend that you disable this for large time intervals. For more information, refer to #12.
    From and ToLets you choose the hours to display. This can be used to set working hours, or to filter parts of the day with low traffic


    Show legendToggles the color spectrum
    Show value indicatorToggles an indicator that shows the current value in the legend
    Gradient qualityDetermines the quality of the color spectrum. Higher quality means more SVG elements being drawn. Reduce the quality if you experience degraded performance.

    Field options

    CalculationCalculation to use for reducing data within a bucket
    Color paletteColors to use for the heatmap. Select from any of the predefined color palettes, or select Custom to create your own. Select Field options to use the colors from the built-in Color scheme field option
    Invert color paletteInverts the currently selected color palette


    Missing data

    By default, data sources limits the number of data points to the width of the panel in pixels. If you're visualizing data over a long time, then you may need to adjust the Max data points under Query options in the query editor.
