Inject extra JavaScript while exporting

You can add a custom JavaScript file while exporting using the --callbackFilePath option. You can also use this option if you want to change the background style of the dashboard or resize the chart while exporting. To do this, you can use the CLI or SDKs of the languages mentioned below, using the commands given below:


    using System;
    using System.IO;
    using System.Linq;
    using FusionCharts.FusionExport.Client; // Import sdk

    namespace FusionExportTest {
        public static class InjectJsCallback {
            public static void Run(string host = Constants.DEFAULT_HOST, int port = Constants.DEFAULT_PORT) {
                // Instantiate the ExportConfig class and add the required configurations
                ExportConfig exportConfig = new ExportConfig();
                exportConfig.Set("chartConfig", File.ReadAllText("./resources/dashboard_charts.json"));
                exportConfig.Set("templateFilePath", "./resources/template.html");
                exportConfig.Set("callbackFilePath", "./resources/callback.js");

                // Instantiate the ExportManager class
                ExportManager em = new ExportManager(host: host, port: port);
                // Call the Export() method with the export config and the respective callbacks
                em.Export(exportConfig, OnExportDone, OnExportStateChanged);
            }

            // Called when export is done
            static void OnExportDone(ExportEvent ev, ExportException error) {
                if (error != null) {
                    Console.WriteLine("Error: " + error);
                } else {
                    var fileNames = ExportManager.GetExportedFileNames(ev.exportedFiles);
                    Console.WriteLine("Done: " + String.Join(", ", fileNames)); // export result
                }
            }

            // Called on each export state change
            static void OnExportStateChanged(ExportEvent ev) {
                Console.WriteLine("State: " + ev.state.customMsg);
            }
        }
    }

            // Instantiate the ExportConfig class and add the required configurations

            config.set("chartConfig", configPath);

            config.set("callbackFilePath", "fullPath/callback.js");

            // Instantiate the ExportManager class
            ExportManager manager = new ExportManager(config);
            // Call the export() method with the export config and the respective callbacks

                            System.out.println(error.getMessage());
                        } else {
