In charts color with a gradient can be introduced on a specific measure field.
For example, we have one state dimension and 2 measure columns for total sales and profit/loss.
As of now if we want to show these we can use a combo chart, or stacked bar chart but to show all this information in one chart without any addons is not possible.
Improvement: We can introduce an additional feature in charts where the other measure can depict a gradient of color. This way a chart with a simple structure can be used to convey more information.
Here we can plot the city and total sales bar chart and the profit/loss measure can be depicted by the intensity of colors: be it red or green.
