Charts allow you to view and examine your metrics. You can interact directly with charts in real time--zoom in, zoom out, change the time window, and so on.
Users with dashboard permission can customize many aspects of the chart and save their changes. This page is a detailed reference to the tabs in the different chart types. We repeat tab reference for each chart type. |
 |
Data Tab (All Charts)
For each chart (with the exception of a Markdown chart) you specify one or more queries.
When you select Data, you can:
- View queries for the chart and add lines.
- Use Chart Builder or Query Editor.
- Clone, delete, or hide one or more lines.
- Create an alert based on a chart.
- Bring up AI Genie for anomaly detection and forecasting.
Line Plot Chart
Line plots are well suited both for single time series and multiple time series. You can customize many aspects of your line plots.
A line plot represents interpolated point buckets. The X axis represents the amount of time in your time window and the Y axis represents the value associated with the data based on that time.
Missing data is represented by a dashed line. The dashed line only gives a visual representation of the data stream; it does not represent values of the missing data. If you hover over the chart, you won’t see values where the gap threshold has been applied. Use the Format > Gap Threshold property to set the amount of time before gaps of missing data display as dashed lines.
Format Tab
| Option | Description |
|---|---|
| Summarization | Summarization method for grouping raw, reported data points, and for mapping them to displayable values. When displaying metrics, Wavefront determines the chart resolution and establishes an appropriate time interval as the chart's bucket size. Wavefront then aggregates (combines) the raw data values that are reported within each time interval (bucket) and produces a single value to display for each bucket. The chosen summarization method determines how the aggregation is performed.
|
| Display Source Events | If checked, displays events that were generated by alerts associated with any source displayed on the chart. You can also use events() queries to Display events in charts. |
| Gap Threshold | Controls when data is considered missing when there are gaps in the reporting of the data. The gap threshold is expressed in seconds and defaults to 60 seconds. |
Axis Tab
The Axis tab lets you customize the Y axis. The customization is the same for both Line Plot and Point Plot. See Use a Logarithmic Y Axis for Skewed Data and Use ICE/Binary Prefixes in Y Axes and Legends for instructions.
| Option | Description |
|---|---|
| Y-Axis | Scale of the Y-axis: linear or logarithmic. Default is linear. In most cases, linear is sufficient as long as there is not a large difference in measurement between the reported data points. If there's a large difference in measurement scale, use the logarithmic scale. By default, the logarithmic scale is set to the power of 10. You can configure the scale in the adjacent text field. |
| Min/Max | Minimum and maximum value on the Y-axis. If you are using a double Y-axis, you can specify min/max values for each Y-axis (By default, set to auto). |
| Unit | Unit of measurement to assign to the label that appears along the Y-axis. This unit does not change the unit of measurement. If you are using a double Y-axis, you can specify a unit for each Y-axis.
Supported units are:
If you select ICE/Binary Unit Prefixes, then Wavefront uses 1024 instead of 1000 as the step to the next unit prefix. For details on unit prefixes and dynamic units, see Units in Chart Axes and Legends. |
Legend Tab

Markdown Chart
A Markdown chart allows you to provide in-depth text descriptions of a dashboard and individual charts using Markdown. We support CommonMark
In addition to Markdown formatted text, you can use links, images hosted outside Wavefront, and dashboard variables. You can refer to the value of a dashboard variable with the query variable syntax ${var_name} and the label of the variable using %{var_name}. Using a label instead of the variable value could be useful for list variables that might show the dropdown labels such as: Any, 1 Year, 3 Years which could map to opaque values such as -1, 1, 3.
|
Single Stat Chart
By default, a single stat chart plots a single series on a chart and displays a summarized value for that series in large font on the chart. The font size and placement of the displayed value can be unique for each chart. A common use case is displaying instantaneous values of critical metrics on an overhead display.
Format Tab
| Option | Description |
|---|---|
| Summarization | Summarization method for grouping raw, reported data points, and for mapping them to displayable values. When displaying metrics, Wavefront determines the chart resolution and establishes an appropriate time interval as the chart's bucket size.

Node Map Chart
A node map chart shows colored 3-D cubes ordered from highest to lowest. a node map that shows data based on source values.
- By default, the node map uses displays the highest value on the top left to catch the user’s eye.
- When a user clicks a node, a small popup of the corresponding metric for that source results.
- Use color mapping to determine colors for higher values. The node map uses shading to show transitions. In the example above, values below 0.3 are shown as green, values lower than 0.8 are shown as a shade of yellow.
- Users can group and can set the metric to display in the top right.
- Specify a drilldown link to direct users to a different dashboard if they click on the dashboard.
When you refresh a node map page, a short animation folds out the chart content.
Color Mapping Tab
The color mapping tab lets you define which set of values maps to which colors. In the example above, values less than 0.3 are green, values less than 0.8 are yellow. All other values are red. See How Do I Set Up Color Mapping for details.
Node Map Defaults Tab
| Option | Description |
|---|---|
| Default Group by | Specifies grouping. |
| Default Metric | Metric you're interested in. Each cube in the node map displays one node and you can, for example, create a set of queries to monitor for CPU, memory, and bandwidth issues. |

Histogram Chart
Histogram charts have two main uses:
- Visualize Wavefront Histograms. Wavefront histograms let you compute, store, and use distributions of metrics rather than single metrics. Histograms are useful for high-velocity metrics about your applications and infrastructure – particularly those gathered across many distributed sources.
- Display a histogram visualization of a time series. That makes it possible, for example, to easily see query results above a certain percentile.
The histogram chart shows the aggregate view of the entire window. For both histogram data and time series data, you can visualize the amount of data in a certain percentile, specify color gradient and axis information, and, most importantly, get details about your histogram data by looking at hover text on each bar.
From the chart’s edit menu, you can go to the corresponding trace (if any).
Data Tab
In contrast to other chart types, you must use the query editor to enter histogram information.
One easy way to show a histogram is from the Histogram browser.
- Select Browse > Histograms
- Drill down to the metric you’re interested in and double-click it to open it in a chart.
You must make sure you’re looking at a metric – it doesn’t make sense to select a folder.
Format Tab
| Option | Description |
|---|---|
| Color Gradient | Lets you select a start and end color for the histogram gradient. |
| Percentile Markers | Display predefined percentile makers as numbers on the chart. You can also |
| Gap Threshold | Controls when data is considered missing when there are gaps in the reporting of the data. The gap threshold is expressed in seconds and defaults to 60 seconds. |
Axis Tab
The Axis tab lets you change the Y axis, and both the X axis dimensions and units.
| Option | Description |
|---|---|
| Y-Axis | Scale of the Y-axis: linear or logarithmic. Default is linear. In most cases, linear is sufficient as long as there is not a large difference in measurement between the reported data points. If there's a large difference in measurement scale, use the logarithmic scale. By default, the logarithmic scale is set to the power of 10. You can configure the scale in the adjacent text field. |
| Min/Max | Y axis minimum and maximum value. Use these two options to change the height of your histogram bars. |
| X-Axis Min / X-Axis Max | Allows you to specify the minimum and maximum on the X axis, in effect, filtering out some of the left-most and right-most bars that the chart displays. |
| Unit | Unit of measurement to assign to the label that appears along the X-axis. This unit does not change the unit of measurement. This unit also does not affect the Y axis.
Supported units are:
If you select ICE/Binary Unit Prefixes, then Wavefront uses 1024 instead of 1000 as the step to the next unit prefix. For details on unit prefixes and dynamic units, see Units in Chart Axes and Legends. |
Advanced Tab
| Option | Description |
|---|---|
| Include Obsolete Metrics | Select this check box to display metrics that have not reported data values in the last 4 weeks. Selecting this option is useful if you are looking at data from 4 or more weeks ago; however, performance is slower when this option is turned on. |
