PlotGraph - A Sublime Text 3 Package

Plot a column of numbers as a graph, or create a quick curve comparison based on multiple number columns.



  • You need a python installation on your computer. The sublime-internal python is not sufficient.

  • That python environment needs to have the following modules installed:

    The latter two are part of the python standard library and are probably available with a standard python installation.

  • To test if your python installation has a module installed, you can do the following:

    • Open a terminal.
    • Start python, e.g. by entering python and hit [Enter].
    • In the started python console, enter e.g.: import matplotlib.
    • If this command finished without an error message you are all set.

Install Using Package Control (recommended)

  • Install Package Control in Sublime Text. (How-To)
  • Once Package Control is installed successfully, hit [ctrl+shift+p].
  • In the command line type something like pa con in pa and select Package Control: Install Package from the drop down list.
  • In the search bar type PlotGraph and hit [Enter].
  • Done.

Manual Installation

  1. Download the zip archive.

  2. Extract the folder PlotGraph-master from the downloaded zip archive.

  3. Rename the folder to PlotGraph.

  4. Copy the renamed folder into Sublime Text's Packages directory.

    • If you are not sure where to find that directory, go to Sublime Text 3 Menu > Preferences > Browse Packages.... This should open a directory in you browser.
  5. Restart Sublime Text 3.


Once PlotGraph is installed, you need to set the path to your local python installation (in which matplotlib and the other modules are working).

Define Python Executable Path

  1. Open Sublime Text 3.

  2. In the menu navigate to Preferences > Package Settings > PlotGraph > Settings - User. If you are accessing the PlotGraph user settings for the first time, that file will be empty.

  3. To get a template for the possible settings, open Preferences > Package Settings > PlotGraph > Settings - Default.

  4. Copy the content of the default PlotGraph settings to the empty user settings file.

  5. Replace the default value for python_exec with the path to your python executable. The content of your PlotGraph user setting file should look somewhat like this:

        "python_exec" : "<path to your python executable>"
  6. Save and close the PlotGraph user settings file.

Set Key Bindings

If your are not happy with using [ctrl+alt+g] as the short cut to generate the plot, you can change the key binding:

  1. Open Sublime Text 3.
  2. In the menu navigate to Preferences > Package Settings > PlotGraph > Key Bindings - Default.
  3. Copy the line {"keys": ["ctrl+alt+g"], "command": "plot_graph"} to your user key binding settings. You can open the user key bindings file via Preferences > Package Settings > PlotGraph > Key Bindings - User.
  4. In the user key bindings file, replace the ctrl+alt+g in ["ctrl+alt+g"] with whatever short cut you prefer.
  5. Save and close the user key bindings file.


Select the numbers you want to see plotted (with one selection). If other content is also selected, that's ok, because the selection will be filtered for numbers. Once the selection is made, hit [ctrl+alt+g] to create a matplotlib window. If you select one column of numbers, they will be printed over their index.



Plot one column

If you select two columns, the first one will be used as the values on the abscissa/x-axis and the second column as the values on the ordinate/y-axis.

 1.0  0.0 
 2.0  4.0 
 3.0  3.0 
 4.0  5.0 
 5.0  5.0 
 6.0  5.0 
 7.0  4.0 
18.0  0.0 

Plot two columns

If more than two columns are selected, the first one will be used as the values on the abscissa/x-axis. The other columns will be printed as values on the ordinate/y-axis for different curves.

 1.0  0.0   11.1
 2.0  4.0  -11.2
 3.0  3.0   11.3
 4.0  5.0  -11.4
 5.0  5.0   11.5
 6.0  5.0  -11.6
 7.0  4.0   11.7
18.0  0.0  -11.8

Plot three columns
