== Calculate from data ==
This setting determines if the data is already a calculated heatmap (from the datasource/transformer), or one that should be calculated in the panel.

== X Bucket ==
This setting determines how the X-axis is split into buckets. You can specify a time interval in the Size input. For example, a time range of 1h makes the cells 1-hour wide on the X-axis.

== Y Bucket ==
This setting determines how the Y-axis is split into buckets.

== Y Bucket scale ==
Select one of the following Y-axis value scales:

* linear - Linear scale.
* log (base 2) - Logarithmic scale with base 2.
* log (base 10) - Logarithmic scale with base 10.

== Y Axes ==
Defines how theY axis is displayed

=== Placement ===

* Left On the left
* Right On the right
* Hidden Hidden

=== Unit ===
Unit configuration

=== Decimals ===
This setting determines decimal configuration.

=== Min/Max value ===
This setting configures the axis range.

=== Reverse ===
When selected, the axis appears in reverse order.

== Colors ==
The color spectrum controls the mapping between value count (in each bucket) and the color assigned to each bucket. The leftmost color on the spectrum represents the minimum count and the color on the right most side represents the maximum count. Some color schemes are automatically inverted when using the light theme.

You can also change the color mode to Opacity. In this case, the color will not change but the amount of opacity will change with the bucket count

=== Mode ===
Scheme - Bucket value represented by cell color.

Scheme - If the mode is scheme, then select a color scheme.

opacity- Bucket value represented by cell opacity. Opaque cell means maximum value.

Color- Cellbase color.

Scale- Scale for mapping bucket values to the opacity.

linear- Linear scale. Bucket value maps linearly to the opacity.

sqrt - Power scale. Cellopacity calculated as value ^ k, where k is a configured Exponent value.If exponent is less than 1, you will get a logarithmic scale. If exponent is greater than 1, you will get an exponential scale. In case of 1, scale will be the same as linear.

Exponent - value of the exponent, greater than 0.

=== Start/end color from value ===
By default, FojiSoft calculates cell colors based on minimum and maximum bucket values. With Min and Max you can overwrite those values. Consider a bucket value as a Z-axis and Min and Max as Z-Min and Z-Max, respectively.

* Start - Minimum value using for cell color calculation. If the bucket value is less than Min, then it is mapped to the “minimum” color. The series min value is the default value.
* End - Maximum value using for cell color calculation. If the bucket value is greater than Max, then it is mapped to the “maximum” color. The series max value is the default value.

== Cell display ==
Use these settings to refine your visualization.

== Additional display options ==

=== Tooltip ===

* Show tooltip - Show heatmap tooltip.
* Show Histogram - Show a Y-axis histogram on the tooltip. A histogram represents the distribution of the bucket values for a specific timestamp.

=== Legend ===
Choose whether you want to display the heatmap legend on the visualization.

=== Exemplars ===
Set the color used to show exemplar data.
