To create a table like this, you need to install the Dataview plugin and enable YAML in the note

What a simple table that pulls information from YAML looks like:

Code to insert:

```dataviewjs
const pages = dv.pages('"2. Areas/Занятие спортом/Динамика веса"')
  .where(p => p.Вес && p.date)
  .sort(p => p.date);

let rows = [];
let prevWeight = null;
const goal = 80;

for (let p of pages) {
  const date = new Date(p.date).toLocaleDateString();
  const weight = p.Вес;
  let diffDisplay = "–";
  let toGoal = `${(goal - weight).toFixed(1)} kg`;

  if (prevWeight !== null) {
    const diff = weight - prevWeight;
    if (diff > 0) {
      diffDisplay = `🟢 +${diff.toFixed(1)}`; // gaining weight = good
    } else if (diff < 0) {
      diffDisplay = `🔴 ${diff.toFixed(1)}`;  // losing = bad
    } else {
      diffDisplay = "➖ 0";
    }
  }

  rows.push([date, weight, diffDisplay, toGoal]);
  prevWeight = weight;
}

dv.table(["📅 Date", "⚖️ Weight (kg)", "📈 Difference", "🎯 To goal (80 kg)"], rows);```

→ const pages = dv.pages(‘“2. Areas/Занятие спортом/Динамика веса”’) — replace with your own path where your notes with YAML are stored → Move the last three apostrophe characters to a new line

🧠 An explanation for those who want to understand this code more deeply:

This code isn’t just a table. It’s a smart weight tracker right inside Obsidian. It shows:

• the entry date;

• the current weight;

• the change in weight compared to the previous entry;

• how much is left to the goal (e.g. 80 kg).

And all of it — automatically, without Excel or third-party apps.

How is dataviewjs different from regular dataview?

Regular dataview	dataviewjs
You write it like in Excel: just table, sort, filter.	You use JavaScript — which means you can do more complex logic: comparisons, calculations, emotions.
Good for simple lists and tables.	Good for advanced trackers, calculations, visualisations.
Can’t calculate the difference between values.	Can compare, calculate the difference and even output emoji depending on the result.

A step-by-step explanation of the code

const pages = dv.pages('"2. Areas/Занятие спортом/Динамика веса"')
  .where(p => p.Вес && p.date)
  .sort(p => p.date);

• We take all the notes from the “Weight dynamics” folder.

• We filter: we only need the ones that have both weight and date.

• We sort by date — so it’s in order.

---

let rows = [];
let prevWeight = null;
const goal = 80;

• rows — the table rows will be gathered here.

• prevWeight — we’ll remember the previous weight to compare with the current one.

• goal — your goal (e.g. 80 kg). The code will show how much is left.

---

for (let p of pages) {
  const date = new Date(p.date).toLocaleDateString();
  const weight = p.Вес;

• We get the date and weight from each note.

• We make the date readable (e.g. “27.05.2025”).

---

let diffDisplay = "–";
let toGoal = `${(goal - weight).toFixed(1)} kg`;

• diffDisplay — what happened to the weight since last time.

• toGoal — how much is left to the goal in kilograms.

---

if (prevWeight !== null) {
  const diff = weight - prevWeight;
  if (diff > 0) {
    diffDisplay = `🟢 +${diff.toFixed(1)}`;
  } else if (diff < 0) {
    diffDisplay = `🔴 ${diff.toFixed(1)}`;
  } else {
    diffDisplay = "➖ 0";
  }
}

• We compare the weight: did it go up, down or stay the same.

• We add a colour and an emoji:

  • 🟢 gained weight — good!

  • 🔴 lost — maybe you need to eat 😅

  • ➖ stayed the same — stability!

---

rows.push([date, weight, diffDisplay, toGoal]);
prevWeight = weight;

• We add everything to the table.

• We remember the current weight to compare with the next one.

---

dv.table(["📅 Date", "⚖️ Weight (kg)", "📈 Difference", "🎯 To goal (80 kg)"], rows);

• We output a nice table:

  • date,

  • weight,

  • change,

  • how much is left to the goal.

💥 The result

You get a table right in Obsidian that:

• calculates progress;

• shows where you’re losing or gaining;

• motivates you to continue.

It’s the perfect tool for self-development and tracking progress. And you made it yourself — without Excel, without apps, just on the basis of Obsidian.
