waterfall chart

Try this

Create a Custom Column for Colors:
In your data model, create a custom column that assigns a unique color to each category. You can use a DAX formula to define this column.
CategoryColor =
SWITCH(
TRUE(),
[Category] = "Category1", "#FF5733", // Red
[Category] = "Category2", "#33FF57", // Green
[Category] = "Category3", "#3357FF", // Blue
// Add more categories and colors as needed
"#000000" // Default color (black)
)

Add the Custom Column to Your Waterfall Chart:
Add your data to the waterfall chart as usual.
Drag the CategoryColor column to the Legend field well of the waterfall chart.
Format the Waterfall Chart:
Go to the Format pane.
Under Data colors, set the colors for each category based on the CategoryColor column.
Adjust the Chart Settings:
Ensure that the Sentiment option is turned off in the Format pane. This will allow you to use the custom colors instead of the default increase/decrease colors.
