            Values="@Values">
    @* ... *@
</DxBarGauge>

@code {
    public enum Palettes {
        Material,
        Bootstrap,
        Tailwind
    }
    Dictionary<Palettes, string[]> Colors = new Dictionary<Palettes, string[]>() {
        { Palettes.Material, new string[] { "#1db2f5", "#f5564a", "#97c95c" } },
        { Palettes.Bootstrap, new string[] { "#0d6efd", "#6c757d", "#28a745" } },

    };
    Palettes CurrentPalette = Palettes.Material;
    PaletteExtensionMode CurrentPaletteMode = PaletteExtensionMode.Alternate;
    double[] Values = new double[] { -2.13, 1.48, -3.09, 4.52, 4.9, 3.9 };
