# Obsidian Desmos
Render [Desmos](https://www.desmos.com/calculator) 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](manifest.json), [versions.json](versions.json), and [main.js](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](https://en.wikibooks.org/wiki/LaTeX/Mathematics) 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
1. Memory caching **must** be enabled
2. Obsidian **must** have been restarted since you initially created the graph
3. 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.
