# Grid Chart

The description for creating, deleting, and editing the raster diagram can be found in the chapter [Diagrams](/june5-3.7/en/webanwendung/sichten/diagramme.md).

## Setting Options for Measurement Variable

These settings are available via the auxiliary button of the respective measurement variable. The relevant measurement variables are listed in the list view under the heading *Selected*.

* [Measurement Variable Exchange](/june5-3.7/en/webanwendung/sichten/messgroessenaustausch.md)

## Properties

These settings can be found in the [Properties window](/june5-3.7/en/webanwendung/sichten/oberflaeche-und-handling.md).

* Name
* Identification
* [Start Time](/june5-3.7/en/webanwendung/sichten/startzeit.md) *(automatically with current timestamp, absolute or relative)*
* Database
* Color for *null* values
* Reverse Y-Axis
* Color Level Selection
* Min and Max Limit for Color Levels
* Legend (Hide or Change Position: left, top, right, bottom)
* Widget Border Color (*only in Dashboard possible!*)
* Widget Border Width (*only in Dashboard possible!*)

## Ad Hoc Settings

These settings are located on the vertical toolbar. The vertical toolbar is positioned on the left side of the object. The buttons on the vertical toolbar are disabled when the Properties window is opened!

The vertical toolbar provides buttons for the following settings.

* Refresh *(loads newly occurred values from the data source).*
* Database *(opens a dialog in which the data source for all measurement variables can be changed. For example, it is possible to switch between daily or weekly data in the value display).*
* Set Time *(opens a modal window in which the time point/range can be adjusted).*
* Previous Time Interval
* Next Time Interval
* CSV Export (See chapter [Data Export as CSV](/june5-3.7/en/webanwendung/sichten/datenexport-als-csv.md))
* Current Control (Determines the function type of the mouse pointer. For example: Standard, Pan, or Zoom)
* Display (Determines the display of the object in combination with the value table)

## Display

The display of a raster diagram *(heat map)* is done via measurement variables. Select measurement variables from the object list (using the selection button or drag and drop) (See: [Selection and Deselection of Objects](/june5-3.7/en/webanwendung/listenansicht/an-und-abwahl-von-objekten.md)). The raster diagram shows:

* A measurement variable in the form of a thermal image. The measured values of the measurement variable are displayed in the color spectrum of a thermometer (depending on the set color levels).
* It is used to intuitively get an overview of a large number of measured values and to more easily identify particularly striking values.
* A description with the information "measurement variable, timestamp, and absolute value" when the mouse pointer is held over the diagram.

{% hint style="info" %}

* Only measurement variables with numerical values can be inserted into a raster diagram!
* If a measurement variable cannot be inserted into a raster diagram, the values of the affected measurement variable will not be displayed in the table next to or below the raster diagram.
  {% endhint %}
