Graph

Graph

Graph class is simple (at least I hope so) class for rendering graphs.

Initialization

LibGui::Graph MyGraph(
   MyWindow, // you don't have to put this parameter here
   {100, 100}, // position
   {400, 400}, // desired size
   &myData,   // vector<float> pointer to data source
   roboto      // font
);

Usage

// create your data vector
std::vector<float> myData = {0, 1, 1, 2, 3, 5, 8, 13, 21, 34};

// create graph
LibGui::Graph MyGraph({100, 100}, {400, 400}, &myData, roboto);

while (!MyWindow.ShouldClose())
{
   MyWindow.Draw();

   MyGraph.Render();

   MyWindow.PushDraw();
}

Warning

If you update your datasource, don't forget to also update your graph by calling Update() function.

Methods

void Update()

Updates graph to new version of datasource. Don't worry about using it, as it only takes $O(N)$.

void Render()

Renders graph.

bool Rect_OnMouseEnter(Vec2 anchor)

Returns if mouse cursor is on this graph, ignore anchor parameter, as it's override of RectangleInput::Rect_OnMouseEnter.

Properties

Type	Name	Description
std::vector<float>*	data_source	pointer to a vector holding source data
——————————	——————————	——————————
float	scale	scales whole graph
Vec2	position	position of graph
Vec2	anchor	center of graph
Vec2	desired_size	size of graph (without padding and text)
Vec2	background_padding	Is added with desired size (and some more stuff), to get size of background.
Vec2	finalSize	Final size of graph.
——————————	——————————	——————————
Color	lineColor	color of data line in graph
Color	textColor	color of text
Color	infoLineColor	color of support lines
Color	backgroundColor	background color
——————————	——————————	——————————
bool	anyText	Should Render function render labels in the graph?
float	fontSize	text size
int	textLeftOffset	how much space is between labels and graph
float	infoLineDelta	every [how much?] value should be rendered support line

Yes I used m-dashes here, now I'm officially AI. :(
