SFGraphing












A C++ Plot Library to be used in combination with SFML





    

    

    

Newest Version




Entirely rewritten for better readability.  


Added Piecharts! 


You can now set Position and Dimension of Plots



How to use


Documentation at: https://jerr-it.github.io/SFGraphing/


The file main.cpp provides more details on how to use this library

By default a sample program will be created.

How to compile this example 


```

cmake .

make graphing

./graphing

```

Depending on your OS and installation, you might need to adjust the SFML path in SFPlot/CMakeLists.txt to fit your installation of SFML.


Include header in your main file

```c++

#include "SFGraphing/SFPlot.h"

#include "SFGraphing/SFPieChart.h"

```

Important: You need a font, otherwise text wont display!

```c++

sf::Font font;

font.loadFromFile("YourFontHere.ttf");

```

Plot


Create a dataset

```c++

std::vector xAxis = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

std::vector yAxis = {1, 2, 3, 4, 5, 6, 5, 6, 7, 8};

PlotDataSet set(xAxis, yAxis, sf::Color::Green, "Green Data", PlottingType::LINE);

```

Available plotting types are POINTS, LINE and BARS

Create your plot and add your dataset

```c++

//Position, dimension, margin, font

SFPlot plot(sf::Vector2f(800, 0), sf::Vector2f(800, 800), 50, &font, "X Axis", "Y Axis");

plot.AddDataSet(&set);

```

Initialize the plott

```c++

//x-minimum, x-maximum, y-minimum, y-maximum, x-step-size, y-step-size, Color of axes

plot.SetupAxes(0, 10, 0, 10, 1, 1, sf::Color::White);

plot.GenerateVertices();

```

In case you want SFPlot to determine the axes scaling and numbering automatically, call without parameters:

```c++

plot.SetupAxes();

plot.GenerateVertices();

```

Display data (int your window loop)

```c++

window.clear();

window.draw(plot);

window.display();

```

Want to update data in real time?

```c++

window.clear();

plot.ClearVertices();

set.SetDataValue(0, set.GetDataValue(0) + sf::Vector2f(0, 0.001));

plot.SetupAxes();

plot.GenerateVertices();

window.draw(plot);

window.display();

```

Pie Chart


Create dataset

```c++

std::vector values = {100, 230, 150, 100};

std::vector colors = {sf::Color::Blue, sf::Color::Red, sf::Color::Magenta, sf::Color::Cyan};

std::vector labels = {"A", "B", "C", "D"};

//Representations: ABSOLUTE, RELATIVE

PieChartDataSet pSet(values, labels, Representation::RELATIVE, colors);

```

Create PieChart

```c++

//Dataset, Position, Radius, Font

SFPieChart pChart(&pSet, sf::Vector2f(250, 400), 200, &font);

```

Initialize

```c++

pChart.GenerateVertices();

```

Display

```c++

window.clear();

window.draw(pChart);

window.display();

```

Update data in real time?

```c++

window.clear();

pChart.ClearVertices();

pSet.SetValue(0, pSet.GetValue(0) + 0.003);

pChart.GenerateVertices();

window.draw(pChart);

window.display();

```
