@Neopentane1 I don't think this is possible, but it would be a great addition to ScottPlot!

Do you want to make the code change and submit it as a pull request? If so, I would be happy to review it and merge quickly so it can be in the next release!

Looking at how FlipVertically is implemented, I'm sure you can squeeze in a similar FlipHorizontally option:

ScottPlot/src/ScottPlot4/ScottPlot/Plottable/Heatmap.cs

Lines 171 to 174 in 181be95

    
           /// <summary> 
        
           /// If true the Heatmap will be drawn from the bottom left corner of the plot. Otherwise it will be drawn from the top left corner. Defaults to false. 
        
           /// </summary> 
        
           public bool FlipVertically { get; set; } = false;

ScottPlot/src/ScottPlot4/ScottPlot/Plottable/Heatmap.cs

Lines 461 to 464 in 181be95

    
           if (FlipVertically) 
        
           { 
        
               gfx.ScaleTransform(1, -1); 
        
           }

Heatmap content is flipped vertically #1864

PS: I tried flipping it like this but it did not work:

var plt = new ScottPlot.Plot(600, 400);
double[,] imageData = ScottPlot.DataGen.SampleImageData();
var hm = plt.AddHeatmap(imageData);
hm.XMax = 0;
hm.XMin = imageData.Length;
plt.SaveFig("flip.png");

	/// <summary>
	/// If true the Heatmap will be drawn from the bottom left corner of the plot. Otherwise it will be drawn from the top left corner. Defaults to false.
	/// </summary>
	public bool FlipVertically { get; set; } = false;

Heatmap: Flip horizontally #2444
