### Initialize and Render Charts with Theming

Source: https://github.com/gebeto/telegram-charts/blob/main/src/plain.html

This snippet demonstrates how to initialize the charting library, handle dark mode toggling, and render charts by fetching data from JSON files. It also includes a mechanism for handling zoom events by fetching extended data.

```JavaScript
import Graph from './index.js';
var html = document.querySelector('html');
var chartsContainer = document.querySelector('#container');

document.getElementById('dark-mode').addEventListener('click', function handleChangeTheme() {
  html.className = (html.className.replace(/\bdark\b/, '') + ' dark').replace(/\s+/, '');
  document.dispatchEvent(new Event('darkmode'))
});

document.getElementById('light-mode').addEventListener('click', function handleChangeTheme() {
  html.className = html.className.replace(/\bdark\b/, '');
  document.dispatchEvent(new Event('darkmode'))
});

fetch('stage_2_data/1/overview.json').then(res => res.json()).then(chartData => {
  chartData.x_on_zoom = (timestamp) => {
    const response = fetch('stage_2_data_extended/1/2018-04/07.json').then(res => res.json())
    return response;
  };
  Graph.render(chartsContainer, chartData);
})

fetch('stage_2_data/2/overview.json').then(res => res.json()).then(chartData => {
  chartData.x_on_zoom = (timestamp) => {
    const response = fetch('stage_2_data_extended/2/2018-04/07.json').then(res => res.json())
    return response;
  };
  Graph.render(chartsContainer, chartData);
})

fetch('stage_2_data/3/overview.json').then(res => res.json()).then(chartData => {
  chartData.x_on_zoom = (timestamp) => {
    const response = fetch('stage_2_data_extended/3/2018-04/07.json').then(res => res.json())
    return response;
  };
  Graph.render(chartsContainer, chartData);
});

fetch('stage_2_data/4/overview.json').then(res => res.json()).then(chartData => {
  chartData.x_on_zoom = (timestamp) => {
    const response = fetch('stage_2_data_extended/4/2018-04/07.json').then(res => res.json())
    return response;
  };
  Graph.render(chartsContainer, chartData);
});

fetch('stage_2_data/5/overview.json').then(res => res.json()).then(chartData => Graph.render(chartsContainer, chartData))
```

Source: https://github.com/gebeto/telegram-charts/blob/main/src/index.html

Fetches chart data from JSON files and renders it using the Graph library. It also configures an 'x_on_zoom' callback to fetch extended data for specific time ranges when the chart is zoomed.

```JavaScript
var chartsContainer = document.querySelector("#container");
fetch("stage_2_data/1/overview.json")
  .then((res) => res.json())
  .then((chartData) => {
    chartData.x_on_zoom = (timestamp) => {
      const response = fetch(
        "stage_2_data_extended/1/2018-04/07.json"
      ).then((res) => res.json());
      return response;
    };
    Graph.render(chartsContainer, chartData);
  });
fetch("stage_2_data/2/overview.json")
  .then((res) => res.json())
  .then((chartData) => {
    chartData.x_on_zoom = (timestamp) => {
      const response = fetch(
        "stage_2_data_extended/2/2018-04/07.json"
      ).then((res) => res.json());
      return response;
    };
    Graph.render(chartsContainer, chartData);
  });
fetch("stage_2_data/3/overview.json")
  .then((res) => res.json())
  .then((chartData) => {
    chartData.x_on_zoom = (timestamp) => {
      const response = fetch(
        "stage_2_data_extended/3/2018-04/07.json"
      ).then((res) => res.json());
      return response;
    };
    Graph.render(chartsContainer, chartData);
  });
fetch("stage_2_data/4/overview.json")
  .then((res) => res.json())
  .then((chartData) => {
    chartData.x_on_zoom = (timestamp) => {
      const response = fetch(
        "stage_2_data_extended/4/2018-04/07.json"
      ).then((res) => res.json());
      return response;
    };
    Graph.render(chartsContainer, chartData);
  });
fetch("stage_2_data/5/overview.json")
  .then((res) => res.json())
  .then((chartData) => Graph.render(chartsContainer, chartData));
```

### Toggle Dark/Light Theme with Event Listeners

Source: https://github.com/gebeto/telegram-charts/blob/main/index.html

This JavaScript code adds event listeners to buttons for toggling dark and light themes. It manipulates the 'dark' class on the HTML element and dispatches a 'darkmode' event when the theme changes.

```JavaScript
const html = document.querySelector('html');

document.getElementById('dark-mode').addEventListener('click', function handleChangeTheme() {
  const splitted = html.className ? html.className.split(' ') : [];
  const darkIndex = splitted.indexOf('dark');
  if (darkIndex == -1) {
    splitted.push('dark');
    html.className = splitted.join(' ');
    document.dispatchEvent(new Event('darkmode'))
  }
});

document.getElementById('light-mode').addEventListener('click', function handleChangeTheme() {
  const splitted = html.className ? html.className.split(' ') : [];
  const darkIndex = splitted.indexOf('dark');
  if (darkIndex > -1) {
    splitted.splice(darkIndex, 1);
    html.className = splitted.join(' ');
    document.dispatchEvent(new Event('darkmode'))
  }
});
```

### Toggle Dark/Light Mode in JavaScript

Source: https://github.com/gebeto/telegram-charts/blob/main/src/index.html

Handles the toggling of dark and light modes by manipulating the HTML class attribute and dispatching a custom event. It listens for clicks on elements with IDs 'dark-mode' and 'light-mode'.

```JavaScript
import Graph from "./index.ts";
const html = document.querySelector("html");
document
  .getElementById("dark-mode")
  .addEventListener("click", function handleChangeTheme() {
    const splitted = html.className ? html.className.split(" ") : [];
    const darkIndex = splitted.indexOf("dark");
    if (darkIndex == -1) {
      splitted.push("dark");
      html.className = splitted.join(" ");
      document.dispatchEvent(new Event("darkmode"));
    }
  });
document
  .getElementById("light-mode")
  .addEventListener("click", function handleChangeTheme() {
    const splitted = html.className ? html.className.split(" ") : [];
    const darkIndex = splitted.indexOf("dark");
    if (darkIndex > -1) {
      splitted.splice(darkIndex, 1);
      html.className = splitted.join(" ");
      document.dispatchEvent(new Event("darkmode"));
    }
  });
```

### Generate Dynamic Chart Data

Source: https://github.com/gebeto/telegram-charts/blob/main/src/plain.html

This function generates additional data columns for charts based on specified lengths and colors. It dynamically extends the dataset by replicating and modifying existing columns to meet the required dimensions.

```JavaScript
var xLen = 1460;
var colLen = 50;
var colors = ["#108BE3","#3497ED","#4BD964","#64ADED","#2373DB","#E8AF14","#FE3C30","#9ED448","#5FB641","#F5BD25","#F79E39","#E65850"];

function generateData(data, xLen, colLen) {
  var origColLen = data.columns.length - 1;
  var origXLen = data.columns[0].length - 1;
  var k = 1;
  for (var i = origColLen + 1; i <= colLen; i++) {
    data.types['y' + (i - 1)] = data.types['y0'];
    data.names['y' + (i - 1)] = 'Column ' + (i);
    data.colors['y' + (i - 1)] = colors[i % colors.length];
    data.columns[i] = data.columns[(i % origColLen) + 1].slice(0);
    k *= 0.9;
    data.columns[i][0] = 'y' + (i - 1);
    for (var j = 1; j < data.columns[i].length; j++) {
      data.columns[i][j] = Math.round(k * data.columns[i][j]);
    }
  }
  for (var i = 0; i <= colLen; i++) {
    for (var j = data.columns[i].length; j <= xLen; j++) {
      if (i == 0) {
        data.columns[i][j] = data.columns[i][j - 1] + (data.columns[i][2] - data.columns[i][1]);
      } else {
        data.columns[i][j] = data.columns[i][(j % origXLen) + 1];
      }
    }
  }
  return data;
}
```
