Metadata Plot |

### Metadata Plot Display

This dialog allows the user to plot metadata values. See screen shot below for an example.

This plot can be used to plot fields of metadata dataset against each other. The fields must be either scalar values or arrays. If there are multiple records available for a metadata dataset the field can be plotted across all records. A right-click on the diagram will bring up a context menu with some additional options.

#### Options Panel

The options panel on the right offers some configuration options. Note that the metadata plot will only show a graph if x-axis and at least the first y-axis are well configured.

##### Header

- Refresh View
  In case of the metadata view this will always be disabled.
- Table View
  Shows the data of the plot in a tabular view. From there, you are able to switch back to the metadata plot view.
- Collapse/Expand Options Panel /
  Collapses or expands the options panel.

##### Center

- Dataset
  Select the metadata element used as dataset for the plot. From this dataset the fields for the X- and Y-axis can be chosen.
- Record
  Select the current record, if any. If multiple records are shown in a single plot this defines the first plot.
- Records/Plot
  Define how many records are shown in the plot. If start record index + num records is greater than the maximum available records, then only the records till the last one record are shown.
- X Field
  Allows to select the field of the dataset to be set a x-axis value provider. The two following fields have a special meaning.
  - Record Index
    Will display the Y fields across the records depending on the settings
  - Array Field Index [n]
    If an array is selected for the Y field, then the array indices are used as x-values.
- Y Field
  Selects the field to be plotted as first range axis.
- Y2 Field
  Selects the field to be plotted as second range axis.
