Usage examples

This guide lists examples of Flexmonster usage in React. They are provided within our sample React project.

Creating the pivot table

The first example demonstrates how to embed Flexmonster into your project with the FlexmonsterReact.Pivot component. See the source code:

• For React + ES6
• For React + TypeScript

Notice how initialization parameters are specified in FlexmonsterReact.Pivot:

<FlexmonsterReact.Pivot
 toolbar={true}
 beforetoolbarcreated={toolbar => {
   toolbar.showShareReportTab = true;
 }}
 shareReportConnection={{
   url: "https://olap.flexmonster.com:9500"
 }}
 width="100%"
 height={600}
 report="https://cdn.flexmonster.com/github/demo-report.json"
/>

Handling events

This usage example focuses on Flexmonster events. See the source code:

• For React + ES6
• For React + TypeScript

The example provides a toggle button to subscribe to all the events and unsubscribe from them.

Under the component, there is a log output. When an event is triggered, the output shows info about that event.

To subscribe to an event, we use the on() method:

pivotRef.current.flexmonster.on(eventName, () => {
  // Handle the event
});

pivotRef.current?.flexmonster.on(eventName, () => {
  // Handle the event
});

To unsubscribe from an event, we use the off() method:

pivotRef.current.flexmonster.off(eventName);

pivotRef.current?.flexmonster.off(eventName);

See the full list of Flexmonster events in our documentation.

Using API calls

The Using API calls section is about interacting with the component through API calls. See the source code:

• For React + ES6
• For React + TypeScript

Use the toggle buttons to enable the read-only mode or switch between the grid and charts.

See how the API calls are used:

• The showGrid() and showCharts() methods allow switching between the views:
  

  ES6

  const showChart = () => {
    pivotRef.current.flexmonster.showCharts("column");
  };
  
  const showGrid = () => {
    pivotRef.current.flexmonster.showGrid();
  };

  TypeScript

  const showChart = () => {
    pivotRef.current?.flexmonster.showCharts("column");
  };
  
  const showGrid = () => {
    pivotRef.current?.flexmonster.showGrid();
  };

• The setOptions() API call is used to make Flexmonster read-only:
  

  ES6

  const readOnly = () => {
    pivotRef.current.flexmonster.setOptions({
      readOnly: true
    });
    pivotRef.current.flexmonster.refresh();
  };

  TypeScript

  const readOnly = () => {
    pivotRef.current?.flexmonster.setOptions({
      readOnly: true
    });
    pivotRef.current?.flexmonster.refresh();
  };

See the full list of Flexmonster API calls.

Updating data

The Updating data section shows how to refresh data at runtime. See the source code:

• For React + ES6
• For React + TypeScript

Each time you click the Update data button, the dataset is updated and loaded to Flexmonster using the updateData() API call:

const updateTheData = () => {
  data = [
    // Updated data
  ];
  // Updating the data in Flexmonster
  pivotRef.current.flexmonster.updateData({ data: data });
};

const updateTheData = () => {
  data = [
    // Updated data
  ];
  // Updating the data in Flexmonster
  pivotRef.current?.flexmonster.updateData({ data: data });
};

Customizing the Toolbar

The Customizing the Toolbar section contains an example of Toolbar customization. See the source code:

• For React + ES6
• For React + TypeScript

Flexmonster is subscribed to the beforetoolbarcreated event via FlexmonsterReact.Pivot props:

<FlexmonsterReact.Pivot
 ref={pivotRef}
 ...
 beforetoolbarcreated={customizeToolbar}
 ...
/>

The customizeToolbar() handler is defined as follows:

const customizeToolbar = (toolbar) => {
  let tabs = toolbar.getTabs();
  toolbar.getTabs = () => {
    tabs = [];
    // Add new tab
    tabs.push({
      id: "fm-tab-newtab",
      title: "New Tab",
      handler: () => showInfo(),
      icon: toolbar.icons.open,
    });
    return tabs;
  };
};

const customizeToolbar = (toolbar: Flexmonster.Toolbar) => {
  let tabs = toolbar.getTabs();
  toolbar.getTabs = () => {
    tabs = [];
    // Add new tab
    tabs.push({
      id: "fm-tab-newtab",
      title: "New Tab",
      handler: showInfo,
      icon: toolbar.icons.open,
    });
    return tabs;
  };
};

As a result, a new tab with custom functionality is added.

Customizing the grid

The Customizing the grid example demonstrates how to highlight a certain measure on the grid using customizeCell. See the source code:

• For React + ES6
• For React + TypeScript

Here is how customizeCell is defined:

<FlexmonsterReact.Pivot
 ref={pivotRef}
 ...
 customizeCell={customizeCellFunction}
 ...
/>

The customizeCellFunction() applies custom CSS to the cells with the "Price" measure:

const customizeCellFunction = (cell, data) => {
  if (data.measure && data.measure.uniqueName === "Price") {
    let backgroundColor = "#00A45A";
    let textShadowColor = "#095231";
    let borderColor = "#009552";
    cell.style["background-color"] = backgroundColor;
    cell.style["color"] = "white";
    cell.style["font-weight"] = "bold";
    cell.style["text-shadow"] = `0px 2px 3px ${textShadowColor}`;
    cell.style["border-bottom"] = `1px solid ${borderColor}`;
    cell.style["border-right"] = `1px solid ${borderColor}`;
  }
};

const customizeCellFunction = (
  cell: Flexmonster.CellBuilder,
  data: Flexmonster.CellData
) => {
  if (data.measure && data.measure.uniqueName === "Price") {
    let backgroundColor = "#00A45A";
    let textShadowColor = "#095231";
    let borderColor = "#009552";
    cell.style = {
      ...cell.style,
      "background-color": backgroundColor,
      "color": "white",
      "font-weight": "bold",
      "text-shadow": `0px 2px 3px ${textShadowColor}`,
      "border-bottom": `1px solid ${borderColor}`,
      "border-right": `1px solid ${borderColor}`,
    };
  }
};

Integrating with Highcharts

See an example of Highcharts integration in the With Highcharts section:

• React + ES6
• React + TypeScript

Here’s how the Highcharts module and Flexmonster Connector for Highcharts are imported:

import "flexmonster/lib/flexmonster.highcharts.js";
import Highcharts from "highcharts";

import "flexmonster/lib/flexmonster.highcharts.js";
import * as Highcharts from 'highcharts';

In the markup, we add a container for Highcharts:

<div className="chart-container">
  <div id="highcharts-container"></div>
</div>

Then Flexmonster is subscribed to the reportcomplete event via FlexmonsterReact.Pivot props:

<FlexmonsterReact.Pivot
 ref={pivotRef}
 ...
 reportcomplete={reportComplete}
 ...
/>

Finally, we define the reportComplete() handler and the chart-drawing function:

const reportComplete = () => {
  pivotRef.current.flexmonster.off("reportcomplete", reportComplete);
  createChart();
};

const createChart = () => {
  pivotRef.current.flexmonster.highcharts.getData(
    // Creating and configuring the chart
  );
};

const reportComplete = () => {
  pivotRef.current?.flexmonster.off("reportComplete", reportComplete);
  createChart();
};

const createChart = () => {
  pivotRef.current?.flexmonster.highcharts?.getData(
    // Creating and configuring the chart
  );
};

Integrating with amCharts

Our sample project contains examples of integration with amCharts 5 and amCharts 4.

amCharts 5

The With amCharts section provides a dashboard with Flexmonster and amCharts 5. See the source code:

• For React + ES6
• For React + TypeScript

Here’s how the amCharts 5 library and Flexmonster Connector for amCharts are imported:

// Importing Flexmonster Connector for amCharts
import "flexmonster/lib/flexmonster.amcharts.js";
// amCharts imports
import * as am5 from "@amcharts/amcharts5";
import * as am5xy from "@amcharts/amcharts5/xy";
import am5themes_Animated from "@amcharts/amcharts5/themes/Animated";

In the markup, we add a container for amCharts:

<div className="chart-container">
  <div id="amcharts-container" style={{ width: "100%", height: "500px" }}></div>
</div>

Then we subscribe Flexmonster to the reportcomplete event via FlexmonsterReact.Pivot props:

<FlexmonsterReact.Pivot
 ref={pivotRef}
 ...
 reportcomplete={reportComplete}
 ...
/>

Finally, we define the reportComplete() handler and chart-drawing functions:

const reportComplete = () => {
  pivotRef.current.flexmonster.off("reportcomplete", reportComplete);
  drawChart();
};

const drawChart = () => {
  pivotRef.current.flexmonster.amcharts.getData(
    {},
    (chartData, rawData) => createChart(chartData, rawData),
    (chartData, rawData) => updateChart(chartData, rawData)
  );
};

const createChart = (chartData, rawData) => {
  // Creating and configuring the chart
};

const updateChart = (chartData, rawData) => {
  // Updating the chart
};

const reportComplete = () => {
  pivotRef.current?.flexmonster.off("reportcomplete", reportComplete);
  drawChart();
};

const drawChart = () => {
  pivotRef.current?.flexmonster.amcharts?.getData(
    {},
    createChart,
    updateChart
  );
};

const createChart = (
  chartData: Flexmonster.GetDataValueObject,
  rawData: Flexmonster.GetDataValueObject
) => {
  // Creating and configuring the chart
};

const updateChart = (
  chartData: Flexmonster.GetDataValueObject,
  rawData: Flexmonster.GetDataValueObject
) => {
  // Updating the chart
};

amCharts 4

The example with amCharts 4 is hidden from the project's side menu, but you can still access it via a direct link: http://localhost:3000/with-amcharts4 (the project's port can be different).

Here is the example's source code:

• For React + ES6
• For React + TypeScript

It is very similar to the code of the amCharts 5 example:

• First, we import amCharts 4 and Flexmonster Connector for amCharts.
• In the markup, we add a container for amCharts.
• Then Flexmonster is subscribed to the reportcomplete event.
• Finally, we define the reportcomplete event's handler and chart-drawing functions.
