Histogram Panel

2 min

the histogram panel displays the distribution of numerical data over a selected time range it groups values into buckets and counts how many values fall into each one each bar represents a bucket, the height of the bar reflects the count of values within that bucket range, and the x axis represents the bucket ranges themselves when to use it the histogram panel is useful for understanding how your data is spread across a range of values you can use it to visualize request durations, error rates, latency distributions, or any other numerical signal, and by switching the time range, you can observe how the distribution shifts after events like a deployment or a traffic spike general settings panel provide a name and description for your panel axes the histogram panel exposes controls under the axes section to adjust how the distribution is visualized after data is fetched x axis 	∙ bucket count (default 30) controls how many buckets the data is grouped into reducing the bucket count downsamples the distribution, giving a more aggregated view; increasing it reveals finer granularity 	∙ bucket offset shifts all bucket ranges by a fixed value for example, an offset of +10 transforms a bucket range of \[x, y] to \[x+10, y+10] this is useful when you want to align bucket boundaries with a specific baseline 	∙ min / max constrains the visible range by discarding buckets that fall outside the specified bounds use this to focus on the meaningful portion of the distribution and filter out extreme values or noise the goal of these controls is to improve readability and make the distribution easier to interpret, depending on the context and characteristics of your data legend the legend section controls how the legend is displayed alongside the histogram mode choose between table (displays legend as a structured table) or list (displays legend as a simple list) values select which aggregate values (e g , min, max, mean) to show alongside each series label leave empty to display labels only time range settings access time range settings for panels by clicking on panel settings > time range https //docs kloudmate com/time range expressions and settings allow you to perform the following override dashboard time range individual panels can use their own time range configuration you can use it to override the dashboard time range by enabling override dashboard time range time shift shift a panel's start and end time by specifying a time shift expression it supports the following operators \ subtract time (required) units same units as dashboard time range expressions
