[wxWidgets] wxCharts 차트 그리기

C, C++ 2026. 5. 4. 16:42 |

wxCharts를 이용해 차트를 그려보자.

Include, Library 등을 적당히 세팅한다.

#include <wx/wx.h>
#include <wxcharts/wx/charts/wxchart.h> // wxCharts 라이브러리의 헤더 파일을 포함한다.
#include <wxcharts/wx/charts/wxbarchartctrl.h> // wxBarChartCtrl 클래스의 헤더 파일을 포함한다.

#pragma comment(lib, "wxchartsd.lib") // wxCharts 라이브러리를 링크한다.

class MyApp : public wxApp
{
public:
	bool OnInit() override;
};

wxIMPLEMENT_APP(MyApp);

class MyFrame : public wxFrame
{
public:
	MyFrame();

private:
	void OnHello(wxCommandEvent& event);
	void OnExit(wxCommandEvent& event);
	void OnAbout(wxCommandEvent& event);

	wxPanel* panel;
};

enum
{
	ID_Hello = 1
};

bool MyApp::OnInit()
{
	MyFrame* frame = new MyFrame();
	frame->Show(true);
	return true;
}

// 메인 프레임의 위치(default position)와 크기(550x400)를 설정한다.
MyFrame::MyFrame() : wxFrame(nullptr, wxID_ANY, "Hello World", wxDefaultPosition, wxSize(550, 400))
{
	wxMenu* menuFile = new wxMenu;
	menuFile->Append(ID_Hello, "&Hello...\tCtrl-H", "Help string shown in status bar for this menu item");
	menuFile->AppendSeparator();
	menuFile->Append(wxID_EXIT);

	wxMenu* menuHelp = new wxMenu;
	menuHelp->Append(wxID_ABOUT);

	wxMenuBar* menuBar = new wxMenuBar;
	menuBar->Append(menuFile, "&File");
	menuBar->Append(menuHelp, "&Help");

	SetMenuBar(menuBar);

	CreateStatusBar();
	SetStatusText("Welcome to wxWidgets!");

	panel = new wxPanel(this, wxID_ANY);

	wxButton* myButton = new wxButton(panel, wxID_ANY, "Press Me", wxPoint(420, 30), wxSize(100, 30));
	myButton->Bind(wxEVT_BUTTON, &MyFrame::OnHello, this);

	Bind(wxEVT_MENU, &MyFrame::OnHello, this, ID_Hello);
	Bind(wxEVT_MENU, &MyFrame::OnAbout, this, wxID_ABOUT);
	Bind(wxEVT_MENU, &MyFrame::OnExit, this, wxID_EXIT);
}

void MyFrame::OnExit(wxCommandEvent& event)
{
	Close(true);
}

void MyFrame::OnAbout(wxCommandEvent& event)
{
	wxMessageBox("This is a wxWidgets Hello World example", "About Hello World", wxOK | wxICON_INFORMATION);
}

void MyFrame::OnHello(wxCommandEvent& event)
{
	//wxLogMessage("Hello world from wxWidgets!");

	// wxCharts 라이브러리를 사용하여 막대 그래프를 생성
	// Create the data for the bar chart widget
	wxVector<wxString> labels;
	labels.push_back("January");
	labels.push_back("February");
	labels.push_back("March");
	labels.push_back("April");
	labels.push_back("May");
	labels.push_back("June");
	labels.push_back("July");
	wxChartsCategoricalData::ptr chartData = wxChartsCategoricalData::make_shared(labels);

	// Add the first dataset
	wxVector<wxDouble> points1;
	points1.push_back(3);
	points1.push_back(2.5);
	points1.push_back(1.2);
	points1.push_back(3);
	points1.push_back(6);
	points1.push_back(5);
	points1.push_back(1);
	wxChartsDoubleDataset::ptr dataset1(new wxChartsDoubleDataset("Dataset 1", points1));
	chartData->AddDataset(dataset1);

	// Add the second dataset
	wxVector<wxDouble> points2;
	points2.push_back(1);
	points2.push_back(1.33);
	points2.push_back(2.5);
	points2.push_back(2);
	points2.push_back(3);
	points2.push_back(1.8);
	points2.push_back(0.4);
	wxChartsDoubleDataset::ptr dataset2(new wxChartsDoubleDataset("Dataset 2", points2));
	chartData->AddDataset(dataset2);

	// Create the bar chart widget
	wxBarChartCtrl* barChartCtrl = new wxBarChartCtrl(panel, wxID_ANY, chartData);
	barChartCtrl->SetSize(400, 300);

	// Set up the sizer for the panel
	//wxBoxSizer* panelSizer = new wxBoxSizer(wxHORIZONTAL);
	//panelSizer->Add(barChartCtrl, 1, wxEXPAND);
	//panel->SetSizer(panelSizer);
}

grid를 없애 보자.

void MyFrame::OnHello(wxCommandEvent& event)
{
	//wxLogMessage("Hello world from wxWidgets!");

	// wxCharts 라이브러리를 사용하여 막대 그래프를 생성
	// Create the data for the bar chart widget
	wxVector<wxString> labels;
	labels.push_back("January");
	labels.push_back("February");
	labels.push_back("March");
	labels.push_back("April");
	labels.push_back("May");
	labels.push_back("June");
	labels.push_back("July");
	wxChartsCategoricalData::ptr chartData = wxChartsCategoricalData::make_shared(labels);

	// Add the first dataset
	wxVector<wxDouble> points1;
	points1.push_back(3);
	points1.push_back(2.5);
	points1.push_back(1.2);
	points1.push_back(3);
	points1.push_back(6);
	points1.push_back(5);
	points1.push_back(1);
	wxChartsDoubleDataset::ptr dataset1(new wxChartsDoubleDataset("Dataset 1", points1));
	chartData->AddDataset(dataset1);

	// Add the second dataset
	wxVector<wxDouble> points2;
	points2.push_back(1);
	points2.push_back(1.33);
	points2.push_back(2.5);
	points2.push_back(2);
	points2.push_back(3);
	points2.push_back(1.8);
	points2.push_back(0.4);
	wxChartsDoubleDataset::ptr dataset2(new wxChartsDoubleDataset("Dataset 2", points2));
	chartData->AddDataset(dataset2);

	// barchart 옵션 설정
	wxBarChartOptions::ptr options(new wxBarChartOptions());

	// 라이브러리의 GetGridOptions()가 const 참조만 반환하므로
	// const_cast를 사용하여 상수성을 일시적으로 제거하여 옵션을 수정한다.
	wxChartsGridOptions& gridOptions = const_cast<wxChartsGridOptions&>(options->GetGridOptions());
	gridOptions.GetHorizontalGridLineOptions().SetShowGridLines(false);
	gridOptions.GetVerticalGridLineOptions().SetShowGridLines(false);

	// Create the bar chart widget with options
	wxBarChartCtrl* barChartCtrl = new wxBarChartCtrl(panel, wxID_ANY, chartData, options);
	barChartCtrl->SetSize(400, 300);

	// Set up the sizer for the panel
	//wxBoxSizer* panelSizer = new wxBoxSizer(wxHORIZONTAL);
	//panelSizer->Add(barChartCtrl, 1, wxEXPAND);
	//panel->SetSizer(panelSizer);
}

세로 막대 그래프를 그려 보자.

}

세로 막대 그래프는 wxColumnChartOptions::prt가 없어서 grid를 없애지 못한다. 아직 완전한 라이브러리는 아닌 것 같다.

라인 차트를 그려보자.

timeseries 차트는 아직 구현이 제대로 된 것 같지 않다. 사용할 수가 없어 라인 차트를 만들어 본 것이다.

아직 제대로 된 튜토리얼이나 문서도 없다. 아래 샘플을 참고하자.
