Hello, From implot.h // ImPlot version string.

define IMPLOT_VERSION "0.13 WIP"

I have modified my example from another ticket to demonstrate a new way to change the color of graph lines. Just use the right mouse button click to do it. Such a behavior shall not happen. The culprit is ImPlot::IsPlotHovered() call. BTW, this call helps this issue https://github.com/epezent/implot/issues/306 a lot. Please, help!!!
