This example illustrates how to add a filter to the table element in the dashboard and store the result in the Excel file.

Installation and running
Use npm to install requred modules:

$ npm install

Run Sample:

$ npm start

Step by step
Stimulsoft Dashboards.JS module loading:

var Stimulsoft = require('stimulsoft-dashboards-js');

Creating new dashboard:

var report = Stimulsoft.Report.StiReport.createNewDashboard();
var dashboard = report.pages.getByIndex(0);

Load and add reg data:

var dataSet = new Stimulsoft.System.Data.DataSet();
dataSet.readXmlFile("Demo.xml");

report.regData("Demo", "Demo", dataSet);
report.dictionary.synchronize();

Create new table element:

var tableElement = new Stimulsoft.Dashboard.Components.Table.StiTableElement();
dashboard.components.add(tableElement);

Add column to table:

var productIDColumns = new Stimulsoft.Dashboard.Components.Table.StiDimensionColumn();
productIDColumns.expression = "Products.ProductID";
tableElement.columns.add(productIDColumns);

Add filter to table:

var productIDFilter = new Stimulsoft.Data.Engine.StiDataFilterRule();
productIDFilter.condition = Stimulsoft.Data.Engine.StiDataFilterCondition.BeginningWith;
productIDFilter.path = "Products.ProductID";
productIDFilter.value = "1";
tableElement.dataFilters.add(productIDFilter);

Export to Excel:

report.exportDocumentAsync((data) => {
    // Converting Array into buffer
    var buffer = Buffer.from(data)

    // File System module
    var fs = require('fs');

    //Saving to a file
    fs.writeFileSync('./SampleDashboard.xlsx', buffer);
}, Stimulsoft.Report.StiExportFormat.Excel2007);

In the screenshot below you can see the result of the sample code:
