color scale legend
for scatter plots, conditional formatting, and line plots, enable data viz to have a legend that is a color scale gradient
1) in scatter plot using saturation, we should have a legend that indicates what the darker and lighter colors represent
2) same goes for conditional formatting in tables and matrices
3) line charts without a field in the "legend" bucket (i.e. line charts represented by a single line) should be eligible for a line graph that has its color change according to a gradient as the value increases or decreases (e.g. a line graph that plots a growth rate could have green as positive growth and red as negative growth)
What's key here is that the legend shows the gradient, which means the max, min, and perhaps a few other points (e.g. middle) would be called out with their numeric value in the legend.
Color saturation needs to be available for the legend feature.
Having a colour saturation legend for the shape map would be extremely helpful
Not having a legend for color saturation makes it very difficult to determine what the colors mean unless you click on the data point. Makes things very clunky
Please add this. It's quite disappointing that a visualization software as big as power bi does not have this.

Please add this, as this is an essential requirement for properly labeling the data visualization.

Color Saturation Legend is required for all visualizaiton
It would be preferable to have color legends for all charts, especially for the shape map.

Legend for Color Saturation is required in whichever chart is applicable.
Color Legend (or color scale) to identify the variable and the values range applied in color saturation with scatter plot and others visuals will be very helpful
The gradient scale for the color legend will also help remove/decrease the limitation of the number of categories plotted on a line chart for example. I have a need to view all lines (within the line chart) of the selected data to surface the most common trend/s.
It is a must for shape maps
Definetely agree for a scale legend for shape maps. it would be essential !
+1. I'm using shape maps. A color scale legend is essential for presentation.
A great example of this, using date as the colour gradient, can be seen here: https://www.accountingweb.co.uk/tech/tech-pulse/coding-for-accountants-training-a-machine-learning-algorithm
