Convert Chart to Image for Japanese Region with C++

In this topic, we will show you how to set the Japanese region for a chart.

Define a Derived Class

First, you need to define a class ChartJapaneseSettings that inherits from ChartGlobalizationSettings.
Then, by overriding the related functions, you can set the text of the chart elements in your own language.

Code example:

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

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

    U16String GetAxisTitleName() override
    {
        return U16String(u"\u8EF8\u30BF\u30A4\u30C8\u30EB");
    }

    U16String GetAxisUnitName(DisplayUnitType type) override
    {
        switch (type)
        {
        case DisplayUnitType::None:
            return U16String(u"");
        case DisplayUnitType::Hundreds:
            return U16String(u"\u767E");
        case DisplayUnitType::Thousands:
            return U16String(u"\u5343");
        case DisplayUnitType::TenThousands:
            return U16String(u"\u4E07");
        case DisplayUnitType::HundredThousands:
            return U16String(u"\u0031\u0030\u4E07");
        case DisplayUnitType::Millions:
            return U16String(u"\u767E\u4E07");
        case DisplayUnitType::TenMillions:
            return U16String(u"\u5343\u4E07");
        case DisplayUnitType::HundredMillions:
            return U16String(u"\u5104");
        case DisplayUnitType::Billions:
            return U16String(u"\u0031\u0030\u5104");
        case DisplayUnitType::Trillions:
            return U16String(u"\u5146");
        default:
            return U16String(u"");
        }
    }

    U16String GetChartTitleName() override
    {
        return U16String(u"\u30B0\u30E9\u30D5\u0020\u30BF\u30A4\u30C8\u30EB");
    }

    U16String GetLegendDecreaseName() override
    {
        return U16String(u"\u524A\u6E1B");
    }

    U16String GetLegendIncreaseName() override
    {
        return U16String(u"\u305E\u3046\u304b");
    }

    U16String GetLegendTotalName() override
    {
        return U16String(u"\u3059\u3079\u3066\u306E");
    }

    U16String GetOtherName() override
    {
        return U16String(u"\u305D\u306E\u4ED6");
    }

    U16String GetSeriesName() override
    {
        return U16String(u"\u30B7\u30EA\u30FC\u30BA");
    }
};

Configure Japanese Settings for Chart

In this step, you will use the class ChartJapaneseSettings you defined in the previous step.

Code example:

Workbook wb("Japanese.xls");
wb.GetSettings().GetGlobalizationSettings().SetChartSettings(new ChartJapaneseSettings());
Chart chart0 = wb.GetWorksheets().Get(0).GetCharts().Get(0);
chart0.ToImage("Output.png");

Then you can see the effect in the output image; the elements in the chart will be rendered according to your settings.

Conclusion

In this example, if you do not set the Japanese region for a chart, the following chart elements may be rendered in the default language, such as English.
After the above operation, you can obtain an output chart image with the Japanese region.

Supported Elements	Value in This Example	Default Value in the English Environment
Axis Title Name	軸タイトル	Axis Title
Axis Unit Name	百,千…	Hundreds, Thousands…
Chart Title Name	グラフタイトル	Chart Title
Legend Increase Name	ぞうか	Increase
Legend Decrease Name	削減	Decrease
Legend Total Name	すべての	Total
Other Name	その他	Other
Series Name	シリーズ	Series
