⚡ Usage

Parameter	Description
<name_of_function>(x)=<math_equation>, <color>, <label>	Function to plot in terms of x. It can have any name, as long as it ends with (x). Color and label can be omitted. You can add as many as you want.
<name_of_function>(x,y)=<math_equation>, <color>	3D Function to plot in terms of x and y. It can have any name, as long as it ends with (x,y). Color can be omitted. You can add as many as you want.
scatter=<x>,<y>,<color>,<label> ; <x2>,<y2>...	Points to render on the graph. Multiple points must be separated with a ;. Color and label can be omitted, but if not, they have to be in the specified order
xmin=<number>	Start of the range on the x-axis that will be plotted
xmax=<number>	End of the range on the x-axis that will be plotted
ymin=<number>	Start of the range on the y-axis that will be plotted (for 3D functions)
ymax=<number>	End of the range on the y-axis that will be plotted (for 3D functions)
num_points=<number>	Number of points of the function that will be plotted on the range (warning: a small number will result in a non-smooth graph)
title=<graph_title>	Title that will be displayed at the top of the graph
x_label=<label>	Label that will be displayed on the x-axis
y_label=<label>	Label that will be displayed on the y-axis
z_label=<label>	Label that will be displayed on the z-axis (for 3D functions)
color=<color>	Color that the functions on the graph will use if not specified
scatter_color=<color>	Color that the points on the graph will use if not specified
line_width=<number>	Width of the function lines
dark_mode=<true/false>	Renders the graph with a suitable view for vaults with dark themes

☑️ If any of these parameters is omitted, the configured default value will be used! You can change them in the plugin's settings tab

Example

   ```juliaplots
   f(x) = x^2, red
   myfunction2(x) = cos(x)
   scatter= 2,1 ; 3,2,red,point1

   xmin = -10
   xmax = 25
   num_points = 100

   title = my graph
   x_label = time (s)
   y_label = velocity (m/s)

   color = rgb(0,255,0)
   scatter_color = black
   line_width = 2
   dark_mode = false
   ```

❗ Known issues

• 🕒 Long waiting time: The plugin can take a long time to generate the graph depending on the user. If you have this problem, it is recommended to use a lower number of plot points.
• 📁 'juliaplots.jl: No such file or directory': This means that the juliaplots.jl file wasn't downloaded and/or isn't in the right directory. Be sure of following the installation steps!
• 🧩 'Please make sure that Julia is installed on your system and that it is included on your PATH': If you already have Julia installed and on your PATH, but it still doesn't work, you can fix this by specifying the full path to the Julia executable in the plugin settings.
