IntelliJ IDEA 2018.3 Help

Scientific Mode

Scientific mode in Python plugin provides support for interactive scientific computing and data visualization. The following packages must be properly installed:

When a numpy import is detected, IntelliJ IDEA shows the banner that suggests you to enable the Scientific mode:

ij enable scientific view

Scientific mode

With this mode enabled, the following changes are introduced to the UI:

  • The Scientific Mode check command in the View menu is automatically selected.

  • Python console is shown.

  • The Documentation tool window appears (a pinned version of the Quick Documentation popup), showing the inline documentation for the symbol at caret:

    py scientific view documentation

  • DataFrame/Array view appears in the Python console and in the Debug tool window.

In the Scientific mode, a graph opens in its own tab in the SciView window, allowing you to resize it, zoom in and out, etc. You can alter this behavior by toggling the Show plots in tool window check box (Settings/Preferences | Tools | Python Scientific).

Matplotlib in the console

Matplotlib is available also in console. See the Running in console section of the Scientific Mode tutorial.

With Matplotlib imported, the following happens:

  • When you open SciView tool window with the debug session stopped, an empty tab is shown, where you can type the variables from the console:
    py scientific view emty tab

    In the Format field, one can specify the format of representing the output.

    Note that when you launch your files in the SciView mode, the command line is automatically shown after the script execution.

  • When stopping on a breakpoint, a tab appears in the SciView with the graph being debugged:
    py matplotlib debug

    See the Debug section of the Scientific Mode tutorial.

When starting a Python console (Tools | Python Console...), one can import Matplotlib, and build graphs as required:

py matplotlib

The Java console is accessible for further inputs.
