### What's New

#### New Features

- FusionCharts version 4.0.0 introduces `Ask FusionDev AI` knowledge base and documentation assistant which:
  - Improves discoverability and unblocks developers by finding instant answers to questions about using FusionCharts.
  - Increases developer productivity by providing instant access to clear, concise, and up-to-date documentation.
  - Improves development efficiency with automated code generation.
- An attribute called `autoUpdateStartEndDateColumn` was introduced. This attribute updates the actual start date / actual end date columns in the Gantt Chart when taskbars are getting dragged.
- An attribute called `allowTaskbarOverlap` was introduced. When this attribute is set to 1, it allows the dragging of the taskbar over adjacent taskbars in the Gantt Chart.
- The attributes `marginLeft`, `marginRight`, `marginTop`, and `marginBottom` were introduced in the milestone option of Gantt Chart. These attributes are used to position the milestone per the numeric value provided.

#### Improvements

- FusionCharts version 4.0.0 improved the behavior of **taskbar dragging** in Gantt charts. Now you will also drag the connectors along with the taskbar, and they will stay connected until the drag ends.
- FusionCharts version 4.0.0 introduced the **increase/decrease width functionality** for taskbars. Whenever the taskbar hovers, the stretch icon at both ends of the taskbar can be used to increase/decrease the same width. An arrow icon was added at the end of taskbars for increasing/decreasing width.
- FusionCharts version 4.0.0 improved the behavior of **taskbar dragging** in the case of parent and child taskbars. The parent taskbars will auto-extend in case the child taskbars are dragged.
- Upgraded framework integrations for React, Angular, Vue & Svelte.
  - React FusionCharts upgraded to v18. React upgraded to version 18 in package.json file.
  - Angular FusionCharts upgraded to v17. Angular packages version upgraded to 17 in package.json folder. Typescript packages are also upgraded to support Angular 17.
  - Vue FusionCharts upgraded to v3. Vue package already had v3, only a minor version upgrade was done in package.json file.
  - Svelte FusionCharts upgraded to v4. Svelte was upgraded to the latest version 4 in package.json file. The bundler used in the Avelte package was rollup which had some old APIs, they were replaced with the new APIs.
- FusionCharts ASP.Net has been updated to support **.NET versions** (6.0, 7.0, and 8.0).
- FusionCharts 4.0.0 enhanced **product stability** and **security** through Automation Repository Upgrade & Optimization.

#### Fixes

- Resolved the issue of `plotHighlightEffect` attribute resetting all the dataset-level attributes when series were shown/hidden using legends.
- Fixed the issue of `resizeTo` method not working when the chart was rendered using XML data format.
- Fixed the issue where charts were not exported on **iPad** with Safari browser.
- Fixed the issue where taskbar drags position update event `dataplotdragmove` was logging duplicate values in Gantt charts.
- Resolved the issue when the tooltip was not visible on the delayed part of taskbars in Gantt charts.
- Resolved the visual bug with data labels and their background when `transposeAxis` was enabled for multi-series bar charts. Improved the visual clarity of Multi-series Bar charts by addressing `transposeAxis` attribute bug.
- Resolved an issue where inline styles used for Pie chart watermarks and tooltips triggered CSP errors, potentially hindering chart display.
- Fixed the bug where the scroll bar position was getting reset to the initial position, when `setChartData` is used to update the chart’s data.
- Handled the case of negative values for radial bar in Radial Bar charts. For **negative values**, the radial bar will stick to the 0 position.
- Fixed the issue where React FusionCharts wrapper was not working in strict mode. In react wrapper, if the chart is already rendered then the `dispose` method is used to delete the instance to avoid render callback in loop.
- Resolved the issue where data values were not visible for plots in the Bar2D chart when the bar width value was very low.
- Optimized user experience with Gauge charts through seamless resizing.

## Getting Started

Easiest way to start with FusionCharts is to include the JavaScript library in your webpage, create a `<div>` container and chart instance, configure the data and render. Check this HTML snippet below:

```javascript
<!doctype html>
<html>
<head>
    <script src="https://cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"></script>
</head>
<body>
    <div id="chart-container"></div>
    <script>
        FusionCharts.ready(function () {
            // chart instance
            var chart = new FusionCharts({
                type: "column2d",
                renderAt: "chart-container", // container where chart will render
                width: "600",
                height: "400",
                dataFormat: "json",
                dataSource: {
                    // chart configuration
                    chart: {
                        caption: "Countries With Most Oil Reserves [2017-18]",
                        subcaption: "In MMbbl = One Million barrels"
                    },
                    // chart data
                    data: [
                        { label: "Venezuela", value: "290000" },
                        { label: "Saudi", value: "260000" },
                        { label: "Canada", value: "180000" },
                        { label: "Iran", value: "140000" },
                        { label: "Russia", value: "115000" },
                        { label: "UAE", value: "100000" },
                        { label: "US", value: "30000" },
                        { label: "China", value: "30000" }
                    ]
                }
            }).render();

## Using Themes

FusionCharts provides several out-of-the box themes that can be applied to all the charts to configure the visual appearance of the charts. Below is an example on how to use a theme:

```html
<!DOCTYPE html>
<html>
  <head>
    <script src="https://cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"></script>
    <script src="https://cdn.fusioncharts.com/fusioncharts/latest/themes/fusioncharts.theme.fusion.js"></script>
  </head>
  <body>
    <div id="chart-container"></div>
    <script>
      FusionCharts.ready(function () {
        // chart instance
        var chart = new FusionCharts({
          type: "column2d",
          renderAt: "chart-container", // container where chart will render
          width: "600",
          height: "400",
          dataFormat: "json",
          dataSource: {
            // chart configuration
            chart: {
              caption: "Countries With Most Oil Reserves [2017-18]",
              subcaption: "In MMbbl = One Million barrels",
              theme: "fusion", //Specifying which theme to use
            },
            // chart data
            data: [
              { label: "Venezuela", value: "290000" },
              { label: "Saudi", value: "260000" },
              { label: "Canada", value: "180000" },
              { label: "Iran", value: "140000" },
              { label: "Russia", value: "115000" },
              { label: "UAE", value: "100000" },
              { label: "US", value: "30000" },
              { label: "China", value: "30000" },
            ],
          },
        }).render();
      });
    </script>
  </body>
</html>
```

### Using themes in ES6

```javascript
import FusionCharts from "fusioncharts/core";

// include chart from viz folder - import ChartType from fusioncharts/viz/[ChartType];
import Column2D from "fusioncharts/viz/column2d";

// include theme from themes folder
import fusionTheme from "fusioncharts/themes/es/fusioncharts.theme.fusion";

// add chart as dependency - FusionCharts.addDep(ChartType);
FusionCharts.addDep(Column2D);
FusionCharts.addDep(fusionTheme);

// instantiate the chart.
var chartInstance = new FusionCharts({
  type: "Column2D",
  renderAt: "chart-container", // container where chart will render
  width: "600",
  height: "400",
  dataFormat: "json",
  dataSource: {
    // chart configuration
    chart: {
      caption: "Countries With Most Oil Reserves [2017-18]",
      subcaption: "In MMbbl = One Million barrels",
      theme: "fusion",
    },
    // chart data
    data: [
      { label: "Venezuela", value: "290000" },
      { label: "Saudi", value: "260000" },
      { label: "Canada", value: "180000" },
      { label: "Iran", value: "140000" },
      { label: "Russia", value: "115000" },
      { label: "UAE", value: "100000" },
      { label: "US", value: "30000" },
      { label: "China", value: "30000" },
    ],
  },
});

// render the chart
chartInstance.render();
```
