// - Setup is locked once you start plotting or explicitly call SetupFinish.
// Do NOT call Setup code after you begin plotting or after you make
// any non-Setup API calls (e.g. utils like PlotToPixels also lock Setup)

// [SECTION] SetNext
//-----------------------------------------------------------------------------
// Though you should default to the `Setup` API above, there are some scenarios

// rich as the Setup API, most common needs are provided. These functions can be

// if (ImGui::Button("Center Plot"))
// ImPlot::SetNextPlotLimits(-1,1,-1,1);
// if (ImPlot::BeginPlot(...)) {
// ...
// ImPlot::EndPlot();
// }
//
// Important notes:
//
// - You must still enable non-default axes with SetupAxis for these functions
// to work properly.

//-----------------------------------------------------------------------------
// [SECTION] Plot Items
//-----------------------------------------------------------------------------
// The main plotting API is provied below. Call these functions between
// Begin/EndPlot and after any Setup API calls. Each plots data on the current
// x and y axes, which can be changed with `SetAxis/Axes`.
//
// The templated functions are explicitly instantiated in implot_items.cpp.
// They are not intended to be used generically with custom types. You will get
// a linker error if you try! All functions support the following scalar types:
//
// float, double, ImS8, ImU8, ImS16, ImU16, ImS32, ImU32, ImS64, ImU64
//
//
// If you need to plot custom or non-homogenous data you have a few options:
//
// 1. If your data is a simple struct/class (e.g. Vector2f), you can use striding.
// This is the most performant option if applicable.
//
// struct Vector2f { float X, Y; };
// ...
// Vector2f data[42];
// ImPlot::PlotLine("line", &data[0].x, &data[0].y, 42, 0, 0, sizeof(Vector2f));
//
// 2. Write a custom getter C function or C++ lambda and pass it and optionally your data to
// an ImPlot function post-fixed with a G (e.g. PlotScatterG). This has a slight performance
// cost, but probably not enough to worry about unless your data is very large. Examples:
//
// ImPlotPoint MyDataGetter(void* data, int idx) {
// MyData* my_data = (MyData*)data;
// ImPlotPoint p;
// p.x = my_data->GetTime(idx);
// p.y = my_data->GetValue(idx);
// return p
// }
// ...
// auto my_lambda = [](int idx, void*) {
// double t = idx / 999.0;
// return ImPlotPoint(t, 0.5+0.5*std::sin(2*PI*10*t));
// };
// ...
// if (ImPlot::BeginPlot("MyPlot")) {
// MyData my_data;
// ImPlot::PlotScatterG("scatter", MyDataGetter, &my_data, my_data.Size());
// ImPlot::PlotLineG("line", my_lambda, nullptr, 1000);
// ImPlot::EndPlot();
// }

// if you try plotting extremely large 64-bit integral types. Proceed with caution!

// [SECTION] Styling
//-----------------------------------------------------------------------------
// Styling colors in ImPlot works similarly to styling colors in ImGui, but
// with one important difference. Like ImGui, all style colors are stored in an
// indexable array in ImPlotStyle. You can permanently modify these values through
// GetStyle().Colors, or temporarily modify them with Push/Pop functions below.
// However, by default all style colors in ImPlot default to a special color
// IMPLOT_AUTO_COL. The behavior of this color depends upon the style color to
// which it as applied:
//
// 1) For style colors associated with plot items (e.g. ImPlotCol_Line),
// IMPLOT_AUTO_COL tells ImPlot to color the item with the next unused
// color in the current colormap. Thus, every item will have a different
// color up to the number of colors in the colormap, at which point the
// colormap will roll over. For most use cases, you should not need to
// set these style colors to anything but IMPLOT_COL_AUTO; you are
// probably better off changing the current colormap. However, if you
// need to explicitly color a particular item you may either Push/Pop
// the style color around the item in question, or use the SetNextXXXStyle
// API below. If you permanently set one of these style colors to a specific
// color, or forget to call Pop, then all subsequent items will be styled
// with the color you set.
//
// 2) For style colors associated with plot styling (e.g. ImPlotCol_PlotBg),
// IMPLOT_AUTO_COL tells ImPlot to set that color from color data in your
// **ImGuiStyle**. The ImGuiCol_ that these style colors default to are
// detailed above, and in general have been mapped to produce plots visually
// consistent with your current ImGui style. Of course, you are free to
// manually set these colors to whatever you like, and further can Push/Pop
// them around individual plots for plot-specific styling (e.g. coloring axes).
// Provides access to plot style structure for permanant modifications to colors, sizes, etc.

// Style plot colors for current ImGui style (default).

// [SECTION] Colormaps
//-----------------------------------------------------------------------------
// Item styling is based on colormaps when the relevant ImPlotCol_XXX is set to
// IMPLOT_AUTO_COL (default). Several built-in colormaps are available. You can
// add and then push/pop your own colormaps as well. To permanently set a colormap,
// modify the Colormap index member of your ImPlotStyle.
// Colormap data will be ignored and a custom color will be used if you have done one of the following:
// 1) Modified an item style color in your ImPlotStyle to anything other than IMPLOT_AUTO_COL.
// 2) Pushed an item style color using PushStyleColor().
// 3) Set the next item style with a SetNextXXXStyle function.
// Add a new colormap. The color data will be copied. The colormap can be used by pushing either the returned index or the
// string name with PushColormap. The colormap name must be unique and the size must be greater than 1. You will receive
// an assert otherwise! By default colormaps are considered to be qualitative (i.e. discrete). If you want to create a
// continuous colormap, set #qual=false. This will treat the colors you provide as keys, and ImPlot will build a linearly
// interpolated lookup table. The memory footprint of this table will be exactly ((size-1)*255+1)*4 bytes.
