# Showing zero mesh value with different color in ListDensityPlot [closed]

I have written a code to find values of a parameter. it shows values in a diagram with colors. I want to find the line which separates positive and negative values of the plot. Here is my code:

ListDensityPlot[datas2r, ClippingStyle -> Automatic, ColorFunction -> "BlueGreenYellow", LabelStyle -> Directive[Thick, Large], FrameLabel -> {Style["Pe", Large], Style["K_B T", Large]},PlotLegends -> BarLegend[Automatic, LegendLabel -> "\[Sigma]",     LabelStyle -> {FontSize -> 30}]]
