plots modify

Modify display properties of plot metrics files.

Synopsis

usage: dvc plots modify [-h] [-q | -v] [-t <name_or_path>] [-x <field>]
                        [-y <field>] [--no-header] [--title <text>]
                        [--x-label <text>] [--y-label <text>]
                        [--unset [<property> [<property> ...]]]
                        target

positional arguments:
  target                Metric file to set properties to

Description

It might be not convenient for users or automation systems to specify all the display properties (such as y-label, template, title, etc.) each time plots are generated with dvc plot show or dvc plot diff. This command sets (or unsets) default display properties for a specific metrics file.

The path to the metrics file target is required. It must be listed in a dvc.yaml file (see the --plots option of dvc run). dvc plots modify adds the display properties to dvc.yaml.

Property names are passed as options to this command (prefixed with --). These are based on the full Vega specification.

Options

  • -t <name_or_path>, --template <name_or_path> - set a default plot template.
  • -x <field> - set a default field or column name (or number) from which the X axis data comes from.
  • -y <field> - set a default field or column name (or number) from which the Y axis data comes from.
  • --x-label <text> - set a default title for the X axis.
  • --y-label <text> - set a default title for the Y axis.
  • --title <text> - set a default plot title.
  • --unset [<property> [<property> ...]] - unset one or more display properties. Use the property name(s) without -- in the argument sent to this option.
  • --no-header - lets DVC know that the target CSV or TSV does not have a header. A 0-based numeric index can be used to identify each column instead of names.
  • -h, --help - prints the usage/help message, and exit.
  • -q, --quiet - do not write anything to standard output. Exit with 0 if no problems arise, otherwise 1.
  • -v, --verbose - displays detailed tracing information.

Examples

The initial plot was showing the last column of CSV file by default which is loss metrics while accuracy is expected as Y axis:

epoch,accuracy,loss
0,0.9403833150863647,0.2019129991531372
1,0.9733833074569702,0.08973673731088638
2,0.9815833568572998,0.06529958546161652
3,0.9861999750137329,0.04984375461935997
4,0.9882333278656006,0.041892342269420624
$ dvc plots show logs.csv
file:///Users/usr/src/myclassifier/logs.html

Changing the y-axis to accuracy:

$ dvc plots modify logs.csv -y accuracy
$ dvc plots show logs.csv
file:///Users/usr/src/myclassifier/logs.html

Note, a new field y was added to dvc.yaml file for the plot. Please do not forget to commit the change in Git if the modification needs to be preserved.

- logs.csv:
    cache: false
    y: accuracy

Changing the plot title and x-label:

$ dvc plots modify logs.csv --title Accuracy -x epoch --x-label Epoch
$ dvc plots show logs.csv
file:///Users/usr/src/myclassifier/logs.html

Two new fields were added to dvc.yaml: x-label and title:

plots:
  - plots.csv:
      cache: false
      y: accuracy
      x_label: epoch
      title: Accuracy

Example: Template change

dvc run —plots file.csv … command assign the default template that needs to be changed in many cases. A simple command changes the template:

$ dvc plots modify classes.csv --template confusion
