What does value scale demonstrate?
Value defines how light or dark a given color or hue can be. Values are best understood when visualized as a scale or gradient, from dark to light. The more tonal variants in an image, the lower the contrast.

Why is it important to remove empty values from a table?
Eliminating empty values when performing calculations can be important because certain calculations, such as an average, can be inaccurate if empty cell values are included. If empty values are stored in your underlying fact table data, by default they will be converted to zeroes when the cube is processed.
