DataviewJS Snippet Showcase

Hello, in my vault i have a folder called work here i create one note for each case i’m working. Inside those notes/cases I create a task list with dates like this - [ ] Do something [🗓️:: 2022-05-23].
Today i use this query to filter my tasks:

.sort(p =>, 'asc')
.where(t => !t.completed))        

My question is:

  1. Can i render task list where i filter only the tasks with [🗓️:: 2022-05-23] maker?
  2. Can i order this list by date of the marker [🗓️:: 2022-05-23] ?
  3. Can i render a list in this parameters: [ ] DATE: LINK_FOR_THE_NOTE

Dataview as of recently supports that emoji notation for certain task fields without the :: to be compatible with the Tasks plugin. If using that shorthand, the calendar/dates emoji turns into a field called due so you can write things like .where(t => t.due) or .sort(t => t.due, 'desc'). I don’t know whether it’ll work like that with your formatting - you’ll have to experiment!

I don’t understand your question 3 - could you elaborate a little more?

Now it renders like this:


And i want to render like this:

I see. I only know how to help with part of that. To get rid of the grouping into different lists, pass false as a second argument to the dv.taskList call. i.e. dv.taskList(..., false). You might be able to change what is displayed per-line by using a call to map(t => ...) at the end of your query after all the filtering and sorting. I imagine you could use that to put the file link in front of the task text for example. However since the due date is part of the task text I’m not sure how you would reorder that.

First, thank you for sharing this and for all your other generous activity in the forum.

Because the Hotkey names are given in terms of Windows naming conventions, e.g. Alt not Opt, it can be confusing. This is particularly true for hotkeys that use the Mac Control key as it also listed as Ctrl. For example:

  • The default Hotkey for Open Settings is listed in this query as Ctrl+,. On a Mac that translates to Command+,
  • If I assign something to Control+, (Mac key names), it also shows up in the DV table as Ctrl+,

Here’s a clipping from the report after assigning Open Vault to “Control+,” as described above.

Both Open Settings and Open Vault appear to be assigned to “Ctrl+,” when, in fact, settings uses Command and Vault uses Control.

Would it be possible to modify the script to show the key names in Mac-speak (Command, Control, Option)?

sorry for the sudden ping on this, but it is almost exactly what I need.
A few short questions:

  1. Is it possible to exlude all notes within anyone of a set of folders when checking how many links some note has? For specific things I need a link threshold of 1, but I don’t want the 85-ish missing lecture files across 15 subjects to show up, nor some equally-yet-to-be-populated TOCs from elsewhere.
  2. Similar to above, could one exclude any file from being shown if the filename itself follows either a specified regex, or just a string-match against an array of blacklisted strings? Basically the same reason, only that I’d need to exclude certain sets of files in directories which also contain files I’d like to see.
  3. Does the snippet also take into account aliases within the frontmatter, or does it only match against exact filenames?

Example of progress visualization via background color.

Problem: I wanted to visualize project progress, but printing just test looks boring and HTML progress element is actually an input which looks redundant. The idea is to use background color under project name, so it doesn’t take extra space. I followed the prototype you can check on StackOverflow.


// project icon, status etc comes from note frontmatter
// you may different props
const projects = dv.pages('"Backlog" and #project').sort(project => project.icon, 'desc');
for (let project of projects) {
    const total = project.file.tasks.length;
    const completed = project.file.tasks.filter((task) => task.completed).length;

    const rootEl = await dv.el('div', '', { cls: 'x-project-status' });
    const progressEl = rootEl.createEl('div', { cls: 'x-progress', attr: { 'data-label': } });
    progressEl.createEl("a", { cls: 'x-percentage-fill', attr: { style: 'width:' + (completed / total * 100) + "%;" } });
    progressEl.createEl("a", { text: '↗', cls: 'x-link', attr: {
        'aria-label-position': 'top',
        target: '_blank',
        rel: 'noopener'
    } });
    progressEl.createEl("span", { text: completed + ' / ' + total, cls: 'x-stat' } );
    rootEl.createEl("span", { text: project.icon + ' ' + project.status, cls: 'x-metadata' } );

I know a teeny tiny bit of dvjs. I have a use case for it that is probably very easy. I’d like to count the number of times a set of words or phrases show up in my “wellness” field. I want to map how many times I’ve done certain things – or logged them at any rate.

field example:
in my daily notes, in my “Bujo” folder, each day has this kind of information.
Wellness: drank water, painkillers, music.

what I’d like is to count how many times I’ve used “water,” “painkillers,” “music” etc.
my daily note title template is 2022-07-06 – Wednesday for example.

Can this be done easily? If so, how?

Thank you.

I want to create a simple chart from my Daily notes with Dataview and/or DataviewJS.
Can you help me with some sample code, please?
Thank you! :smile:

Hi snowbiker100, to make a chart you’ll almost certainly want some additional plugin that makes charts. I know there are several in the community directory. One I have used with dataview fields is obsidian-tracker, which has lots of code examples in an examples dorectory on github, including ones that use dataview fields. Hopefully other folks who have used other chart/graph/data-visualizarion plugins can chime in with advice also!

Do you mean “Obsidian charts” plugin? I’m not directly familiar but this documentation page shows a dataviewjs example. It looks like other pages on that documentation site have an example of a bar chart with multiple bars per day.
A thought independent of the programming: if you put everything on your example diagram on the same chart it is going to be really hard to see the “Fitness” and “Writing” bars because the numbers for “Nutrition” are so big!

Good luck!

@scholarInTraining Thank you so much for your direction. This chart is a good start but it is not aggregating the elements from multiple days. The dataview source is local only to the current page. And yes you are correct long term showing everything on one chart is not practical. I will want to develop weekly and monthly averages for the chart(s). At this first stage, I am trying to keep the chart as simple as possible just bring in the data from multiple daily notes and create a simple chart.


I’m in the process of creating a dictionary of architecture terms and having a blast using dataview(js) for the first time. It makes heavy use of the buttons plugin that pushes data into the YAML as properties.
It automatically generates pages, filters using keywords and properties and can group by different properties. The columns can be enabled and disabled and are all formatted according to their data. One thing I still want to add is a button column that inserts a template into the item, but I will have to figure out how to do that. I’m using some custom css snippets as well to format some stuff a bit neater with subtle animations. The code could definitely be cleaner/ better optimized but its pretty fast up to 500 items per page. Let me know if anyone has questions or tips on optimizing

I have some data with the following formats.

Side_A:: 2
Side_a:: 33
Side_b:: 5555

Side_A:: 1
Side_b:: 4444

Side_A:: 5
Side_b:: 3333

let transpose = m => m[0].map((x,i) => => x[i]));
let p = dv.pages('""')
let result = transpose([p.Side_A, p.Side_a, p.Side_B, p.Side_b])
// result = result.filter(x=>x[0] && x[1].contains(""))

dv.table(["A", "a", "B", "b"], result)

With this code, I succeeded in getting the data table.

A a B b
2 33 444 5555
1 22 333 4444
5 11 222 3333

Now, I’d like to get this table sorted according to A or B.
It would be very thankful if someone can give me a tip.


Add this before the dv.table line to sort by A:

result.values.sort((a, b) => a[0] - b[0])

Add this to sort by B:

result.values.sort((a, b) => a[2] - b[2])


@scholarInTraining thank you so much for your direction. I have been “playing” with the dataview, dataviewjs, and chart plugin. However, I do not see any examples of this idea of a simple chart. I am also hoping (as you) that other folks can provide a simple example. The “Dataview Simple Chart” is a missing link.

Hi @snowbiker100 check out the screenshot in this thread from @metawops - below the code that is giving metawops an issue looks like a chart example. Maybe @metawops can help with your chart questions!

I’m sure we can work things out here, @snowbiker100. :blush:

As @scholarInTraining pointed out I have a rather simple chart inside of one of my notes that shows me the development of the downloads of my “Table to CSV exporter” plugin.
Because the data I want to visualize her resides in a JSON file of some sort/syntax I have to use a dataviewjs block rather than a dataview block because I have to read in the data from the JSON file it’s in and extract the x-axis (called labels in chart.js – on which the plugin “Obsidian Charts” is based) and y-axis data.

Here’s a screenshot of the dataviewjs source left and the result with the “Obsidian Charts” plugin on the right.

If I change the chart type to bar I get a bar chart of the same data like this:

Your data has to be simply inside of a JavaScript array if you use a dataviewjs block.

btw, the “Obsidian Charts” documentation is rather sparse and I find myself often on to learn more about all the options & possibilities. :wink: Browsing the samples there helps me, too.

If you have multiple data sets you’d have to add a 2nd, 3rd, … set to the datasets array – in my case that’s inside the const data structure. Each dataset is a dictionary and should at least contain a label (x-axis) and data (y-axis) key with arrays as values, respectively.

Does this help a bit? Don’t be shy to ask more questions! We’ll get there eventually! :wink:
