colors	string | string[]	Hex colors value (without # prefix) join with ,. Or multiple colors. e.g. colors=f00,0f0,00f,0ff,f0f,ff0 colors=f00&colors=0f0 This will override theme property	undefined

3dbar Animation

Enable animation by passing animation property, available values:

• fall (apper only)

  chart=3dbar&weeks=20&flatten=1&animation=fall
  

  

• raise (apper only)

  chart=3dbar&weeks=20&flatten=1&animation=raise
  

  

• wave (loop)

  chart=3dbar&weeks=20&flatten=1&animation=wave
  

  

Custome animation details: (pass as url query parameters)

fall | raise

• animation_duration <Number> Animation duration in seconds.
• animation_delay <Number> Animation delay in seconds.

wave

• animation_amplitude <Number>
  The extent of the square's movement in pixel(px).
• animation_frequency <Number>
  Frequency of movement of the square, between [0.01, 0.5],
• animation_wave_center <Number>_<Number>
  The center of the wave, pass coordinate points x, y as ${x}_${y}(Join x, y with _) for example 0_0.

DarkMode

In fact, the display of the chart is determined by the theme, which is overridden by the color property. Enabling dark mode here affects the display of the built-in theme and the background color when outputting jpeg or html, while the background is transparent in all other output formats. For more details, see Themes

Charts

  • use: chart=calendar

  • e.g.

    https://ssr-contributions-svg.vercel.app/_/CatsJuice?chart=calendar&format=svg
    

    

• 3dbar

  • use: chart=3dbar

Examples

pin to notion

Use as ios widget with Scritable

code example:

let [chart, widgetSize, theme, weeks] = (args.widgetParameter || "")
  .split(",")
  .map((v) => v.trim());
chart = chart || "calendar";
widgetSize = widgetSize || "midium";
theme = theme || "green";
const darkMode = Device.isUsingDarkAppearance();
let url = `https://ssr-contributions-svg.vercel.app/_/CatsJuice?format=jpeg&quality=2&theme=${theme}&widget_size=${widgetSize}&chart=${chart}&dark=${darkMode}`;

if (weeks) url += `&weeks=${weeks}`;

let w = await createWidget();
Script.setWidget(w);

async function createWidget() {
  let w = new ListWidget();
  let random = (Math.random() * 100000000).toFixed(0);
  let data = await new Request(url + "&random=" + random).load();
  let image = Image.fromData(data);
  w.backgroundImage = image;
  return w;
}

Add scritable widget to home screen, and select script in widget configuration.

Note: The above script relies on the input of the parameter parameter, filling in chart, widgetSize, theme, weeks in order using the , division. here are some examples:

• 3dbar,large,,30

  chart=3dbar&widgetSize=large&weeks=30
  

• 3dbar,,yellow_wine,20

  chart=3dbar&theme=yellow_wine&weeks=20
  

• ,,blue

  theme=blue
  

• ,small,purple

  widgetSize=small&theme=purple
  

flatten-mode

• flatten=1&format=svg

  

• flatten=2&format=svg
