Images / plots

Using static files

put in the image in the public folder
point to the image in <img src="/myimage.png" />
see documentation

Styling

styling can be done using WindiCSS, just add terms to the class attribute

center the image with <img src="/myplot.png" class="mx-auto"/>
you can also control the size with class w-50 or h-50 and adjust the number
you can add shadow, rounder corners, border, padding, etc ...

a complete example looks like:

<img src="/myplot.png" class="m-3 p-3 mx-auto w-90 shadow-xl border-grey border rounded" />

Using Dynamic path

This is if you don't know the filename at build time. You can use the following solution:

const imgUrl = new URL('./img.png', import.meta.url).href

see documentation

Custom components

Link

The Link.vue component allows you to add a link to another slide by simply using <Link target="slide_label" text="go there" /> where slide_label is added as a label property to the front matter of one of your slides. To use, copy the file to your components folder and then write something like:

---
label: slide_a
---

# Hello, this is Slide A

some content

--- 

# Other slide

<Link target="slide_a" text="go to slide A" />

Plotly interactive 3D surface

First install it with npm install plty.js-dist

create a file called plotsimple.vue in the components folder with the following content:

<template>
  <div>
    <div ref="plot1" id="plot1"></div>
  </div>
</template>

<script>
import  Plotly  from 'plotly.js-dist';

var data = [{

export default {
  name: "PlotlyTestv2",
  data: function() {
    return {
      count: 0,
      data:[{ x: [1,2,3,4], y: [10,15,13,17], type:"scatter" }],
      attr: { displayModeBar: true },
      layout: { title: "My graph :)" }
    };
  },
  mounted() {
    Plotly.newPlot(this.$refs.plot1, data, layout);
  }
}
</script>

you can then simply use the <plotsimple /> tag in inside your slides.md file.
