### Description Heatmaps are often read from top to bottom, but the default y axis starts with 0 at the bottom. It can be changed like this: ```fsharp Chart.Heatmap(data,Colorscale=StyleParam.Colorscale.Electric) |> Chart.withY_Axis( Axis.LinearAxis.init(Autorange=StyleParam.AutoRange.Reversed) ) ``` As this is quite common thoughl, i would like to add a `ReverseYAxis` parameter to all `Chart.Heatmap` functions, so i can simply do ```fsharp Chart.Heatmap(data,Colorscale=StyleParam.Colorscale.Electric,ReverseYAxis=true) ```
