Obsidian Desmos

Render Desmos graphs right inside your notes.

Installation

Using Git

If your vault is hosted using git then congratulations, you can use the easy method. Run
git subtree add --prefix .obsidian/plugins/obsidian-desmos https://github.com/Nigecat/obsidian-desmos master --squash
to add the plugin to the vault in the current working directory of your terminal.
You can then run
git subtree pull --prefix .obsidian/plugins/obsidian-desmos https://github.com/Nigecat/obsidian-desmos master --squash
to update the plugin to the latest version (from the same working directory).

Using anything else

Alternatively, if you do not use git or are not comfortable using the terminal, you can manually install the plugin. Download manifest.json, versions.json, and main.js and place them in <vault>/.obsidian/plugins/obsidian-desmos (you may have to create any missing folders).
This process must be repeated to update the application.

Usage

The most basic usage of this plugin involves creating a codeblock with the tag desmos-graph and placing the equations you wish to graph in the body:

    ```desmos-graph
    y=x
    ```

Equations use the LaTeX math format and you can graph multiple equations by placing each one on a seperate line:

    ```desmos-graph
    y=\sin(x)
    y=\frac{1}{x}
    ```

You can restrict the bounds of the graph and apply other settings by placing a --- seperator before your equations. The content before it must be a set of key=value pairs seperated by either newlines or semicolons (or both):

    ```desmos-graph
    boundary_left=0; boundary_right=100;
    boundary_top=10; boundary_bottom=-10;
    ---
    y=\sin(x)
    ```

You can set the dimensions of the rendered image by using the height and width fields.

Restrictions

Note that graph restrictions follow the same format as desmos itself (except we use a | to denote the beginning of the restrictions):

    ```desmos-graph
        y=\sin(x)|{y > 0}
    ```

Style

We support six different types of (case-insensitive) styles:
Line: SOLID DASHED DOTTED
Point: POINT OPEN CROSS

These are placed after the graph restrictions, following another |:

    ```desmos-graph
    y=\sin(x)|{y > 0}|DASHED
    ```

If you do not wish to apply any restrictions, the center field can be left blank:

    ```desmos-graph
    y=\sin(x)||DASHED
    (1,2)||OPEN
    ```

Important

Note that to be able to render these graphs into a PDF the following conditions must be fulfilled

Memory caching must be enabled
Obsidian must have been restarted since you initially created the graph
You must have viewed the rendered graph in the preview since the restart

After these are complete, a standard PDF export should work fine. In the future these steps will be removed and you will be able to directly export them.
