Using ChartGlobalizationSettings Class to Set Different Language for Chart Component with C++

Possible Usage Scenarios

Aspose.Cells APIs have exposed the ChartGlobalizationSettings class in order to deal with the scenarios where the user wishes to set chart component to different language. custom labels for Subtotals in a spreadsheet.

Introduction to ChartGlobalizationSettings Class

The ChartGlobalizationSettings class currently offers the following 8 methods which can be overridden in a custom class to translate such as AxisTitle name, AxisUnit name, ChartTitle name and so on to different language.

1. GetAxisTitleName: Gets the name of Title for Axis.
2. GetAxisUnitName: Gets the Name of Axis Unit.
3. GetChartTitleName: Gets the name of Chart Title.
4. GetLegendDecreaseName: Gets the name of Decrease for Legend.
5. GetLegendIncreaseName: Gets the name of increase for Legend.
6. GetLegendTotalName: Gets the name of Total for Legend.
7. GetOtherName: Gets the name of “Other” labels for Chart.
8. GetSeriesName: Gets the name of Series in the Chart.

Custom language translation

Here, we will create a waterfall chart based on the following data. The names of chart components will be displayed in English in the chart. We will use a Turkish language example to show how to display the Chart Title, Legend Increase/Decrease names, Total name, and Axis Title in Turkish.

Sample Code

The following sample code loads the sample Excel file.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;
using namespace Aspose::Cells::Charts;

class TurkeyChartGlobalizationSettings : public ChartGlobalizationSettings
{
public:
    TurkeyChartGlobalizationSettings() : ChartGlobalizationSettings() {}

    U16String GetChartTitleName() override
    {
        return u"Grafik Başlığı"; // Chart Title
    }

    U16String GetLegendIncreaseName() override
    {
        return u"Artış"; // Increase
    }

    U16String GetLegendDecreaseName() override
    {
        return u"Düşüş"; // Decrease
    }

    U16String GetLegendTotalName() override
    {
        return u"Toplam"; // Total
    }

    U16String GetAxisTitleName() override
    {
        return u"Eksen Başlığı"; // Axis Title
    }
};

void ChartGlobalizationSettingsTest()
{
    // Create an instance of existing Workbook
    U16String pathName = u"input.xlsx";
    Workbook workbook(pathName);

    // Set custom chartGlobalizationSettings, here is TurkeyChartGlobalizationSettings
    TurkeyChartGlobalizationSettings* globalizationSettings = new TurkeyChartGlobalizationSettings();
    workbook.GetSettings().GetGlobalizationSettings()->SetChartSettings(globalizationSettings);

    // Get the worksheet
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Load the chart from source worksheet
    ChartCollection chartCollection = worksheet.GetCharts();
    Chart chart = chartCollection.Get(0);

    // Chart Calculate
    chart.Calculate();

    // Get the chart title
    Title title = chart.GetTitle();

    // Output the name of the Chart title
    std::cout << "\nWorkbook chart title: " << title.GetText().ToUtf8() << std::endl;

    // Get the legend labels
    Vector<U16String> legendEntriesLabels = chart.GetLegend().GetLegendLabels();

    // Output the name of the Legend
    for (int i = 0; i < legendEntriesLabels.GetLength(); i++)
    {
        std::cout << "\nWorkbook chart legend: " << legendEntriesLabels[i].ToUtf8() << std::endl;
    }

    // Output the name of the Axis title
    Title categoryAxisTitle = chart.GetCategoryAxis().GetTitle();
    std::cout << "\nWorkbook category axis title: " << categoryAxisTitle.GetText().ToUtf8() << std::endl;

    delete globalizationSettings;
}

int main()
{
    Aspose::Cells::Startup();
    ChartGlobalizationSettingsTest();
    Aspose::Cells::Cleanup();
    return 0;
}

Output generated by the sample code

This is the console output of the above sample code.

Workbook chart title: Grafik Başlığı

Workbook chart legend: Artış

Workbook chart legend: Düşüş

Workbook chart legend: Toplam

Workbook category axis tile: Eksen Başlığı
