    Motivation

    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.

    Configuration

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

    Display

    OptionDescription
    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.

    Troubleshooting

    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.
