//
// - The #title_id parameter of _BeginPlot_ (see above) does NOT have to be

//   each subplot.
// - The #size parameter of _BeginPlot_ (see above) is ignored when inside of a
//   subplot context. The actual size of the subplot will be based on the
//   #size value you pass to _BeginSubplots_ and #row/#col_ratios if provided.

// [SECTION] Setup
//-----------------------------------------------------------------------------

// The following API allows you to setup and customize various aspects of the
// current plot. The functions should be called immediately after BeginPlot
// and before any other API calls. Typical usage is as follows:

// if (BeginPlot(...)) {                     1) begin a new plot
//     SetupAxis(ImAxis_X1, "My X-Axis");    2) make Setup calls

//     SetupLegend(ImPlotLocation_North);
//     ...
//     SetupFinish();                        3) [optional] explicitly finish setup
//     PlotLine(...);                        4) plot items
//     ...
//     EndPlot();                            5) end the plot
// }
//
// Important notes:
//
// - Always call Setup code at the top of your BeginPlot conditional statement.
// - 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)
// - Calling SetupFinish is OPTIONAL, but probably good practice. If you do not
//   call it yourself, then the first subsequent plotting or utility function will
//   call it for you.

// [SECTION] SetNext
//-----------------------------------------------------------------------------

// Though you should default to the `Setup` API above, there are some scenarios
// where (re)configuring a plot or axis before `BeginPlot` is needed (e.g. if
// using a preceding button or slider widget to change the plot limits). In
// this case, you can use the `SetNext` API below. While this is not as feature
// rich as the Setup API, most common needs are provided. These functions can be
// called anywhere except for inside of `Begin/EndPlot`. For example:

// 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.

// Sets an upcoming axis range limits. If ImPlotCond_Always is used, the axes limits will be locked.
IMPLOT_API void SetNextAxisLimits(ImAxis axis, double v_min, double v_max, ImPlotCond cond = ImPlotCond_Once);
// Links an upcoming axis range limits to external values. Set to nullptr for no linkage. The pointer data must remain valid until EndPlot!

// Sets all upcoming axes to auto fit to their data.
IMPLOT_API void SetNextAxesToFit();

//-----------------------------------------------------------------------------
// [SECTION] Plot Items
//-----------------------------------------------------------------------------

// The main plotting API is provided 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 in your ImPlotSpec.
//    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, {ImPlotProp_Stride, 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(int idx, void* data) {
//        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. 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 permanent modifications to colors, sizes, etc.

// [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.

// When items in a plot sample their color from a colormap, the color is cached and does not change
// unless explicitly overridden. Therefore, if you change the colormap after the item has already been plotted,
