Functions

int NextD3ID()

class D3_Base

#include <d3_init.hpp>

A base object that all D3 objects inherit from. Handles storing the object in Javascript You probably don’t want to instantiate this directly

Subclassed by D3::Axis< D3::LinearScale >, D3::SelectionOrTransition< Transition >, D3::SelectionOrTransition< Selection >, D3::Axis< SCALE_TYPE >, D3::Category10Scale, D3::Category20Scale, D3::Category20bScale, D3::Category20cScale, D3::Dataset, D3::FormatFunction, D3::Histogram, D3::JSFunction, D3::JSObject, D3::Layout, D3::Scale, D3::SelectionOrTransition< DERIVED >, D3::SvgShapeGenerator, D3::ToolTip

Public Functions

inline void Log() const

Protected Functions

inline D3_Base()

Default constructor - adds placeholder to js.objects array in Javascript.

inline D3_Base(int id)

Construct an object pointing to a pre-determined location in js.objects. Warning: This trusts that you know what you’re doing in choosing an id.

inline D3_Base &operator=(const D3_Base &other)

class ToolTip : public D3::D3_Base

#include <d3_init.hpp>

Create a tooltup using the d3.tip Javascript library.

Public Functions

inline ToolTip()

Default constructor - displays whatever data is bound on mouseover.

inline ToolTip(std::string func)

Cosntructor that allows you to specify a function that returns the html for the tooltip. As input, this function should take 3 parameters: the bound data, the index of this item in the selection (int), and a placeholder (int).

Example:

D3::FormatFunction rounded = D3::FormatFunction(".2f");

std::function<double, int, int)> tooltip_display =
  [this](double d, int i, int k) {return "Data: " + to_string(rounded(d));}

D3::ToolTip tip = D3::ToolTip(tooltip_display);

D3::Selection example_selection = D3::SelectAll("circle");

example_selection.SetupToolTip(tip);

Mousing over a circle in the example selection will display “Data: “ followed by the value of d, rounded to two decimal points.

inline void SetHtml(std::string func)

class FormatFunction : public D3::D3_Base

#include <d3_init.hpp>
