|

// However, by default all style colors in ImPlot default to a special color

|
|
// 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
