The DevExpress Blazor BarGauge component allows you to create a custom palette to colorize bars. To apply a color scheme, assign it to the Palette property. If the number of bars exceeds the number of palette colors, you can use the PaletteExtensionMode property to extend the palette.

Use drop-down menus to select a palette and change its extension mode.

The BarGauge component also allows you to export its data in PNG, PDF, JPEG, and SVG file formats. To enable export functionality, add a DxExportSettings object to gauge markup and set the Enabled property to true. You can also configure settings of the exported file (FileName, Margin, and BackgroundColor properties) and enable/disable printing.

Click the Enable Export check box to display the export hamburger menu.
