# Visualizations and graphs

Honeycomb has several types of graphs, to explore your query results in multiple
ways. Most are found in the Graph Settings menu:

You can toggle the following options in the Graph Settings menu:

### Line Graphs or Stacked Graphs

- A
**Line Graph** displays each Break Down group as a line
of values over time. You can read the value at a particular
time directly from the Y axis on the left side of the graph.
- A
**Stacked Graph** displays groups as stacked
colored areas under their line graphs. Each shows a group's relative
contribution to the total. The Y axis reflects the sum of all groups.

### Linear Scale or Log Scale

- The Y axis of a
**Linear Scale** graph increases by a fixed
amount as values increase. It is useful for data with a limited range of
expected values.
- The Y axis of a
**Log Scale** graph increases exponentially.
Each Y value increase represents an order of magnitude (10^{n}) change.
A Log Scale graph is useful for data with an extremely large range of
values.

### UTC Time or Local Time X-Axis

**UTC Time** displays the X axis in
Coordinated
Universal Time, the time at 0° longitude. UTC is sometimes referred to
as Greenwich Mean Time (GMT.) UTC does not observe Daylight Savings Time.
**Local Time** displays the X axis in your browser's local time.

### Omit Missing Values or

Fill Missing Values in with Zeros

**Omit Missing Values** interpolates between points when the
intervening time buckets have no matching events.
**Fill Missing Values in with Zeros** substitutes zero values
for time buckets with no matching events.

## Heatmaps

Heatmaps show the statistical distribution of the values in a dataset column over time.
Unlike the options on the Graph Settings menu, heatmaps require a specific type of query.
To generate a heatmap, add a `HEATMAP`

term to your Calculate clause. For more detail,
see the Heatmaps page.
