The simplest definition for a potential gradient F in one dimension is the following: [1] = = where ϕ(x) is some type of scalar potential and x is displacement (not distance) in the x direction, the subscripts label two different positions x 1, x 2, and potentials at those points, ϕ 1 = ϕ(x 1), ϕ 2 = ϕ(x 2).
Gradient network : ∇ = ∇ (,) where F is the set of gradient edges on G. In general, the scalar field depends on time, due to the flow, external sources and sinks on the network. Therefore, the gradient network ∇ G {\displaystyle G} will be dynamic.
A bar chart may be used to show the comparison across the sales persons. Part-to-whole: Categorical subdivisions are measured as a ratio to the whole (i.e., a percentage out of 100%). A pie chart or bar chart can show the comparison of ratios, such as the market share represented by competitors in a market.
An example is the (nearly) uniform gravitational field near the Earth's surface. It has a potential energy = where U is the gravitational potential energy and h is the height above the surface. This means that gravitational potential energy on a contour map is proportional to altitude. On a contour map, the two-dimensional negative gradient of ...
The simplest algorithm for generating a representation of the Mandelbrot set is known as the "escape time" algorithm. A repeating calculation is performed for each x, y point in the plot area and based on the behavior of that calculation, a color is chosen for that pixel.
a factor multiplied by value to give the width of the bar in pixels. Use the same scale in every row, as otherwise the bar chart won’t be to scale! scale can be negative, in which case an additional column (for showing negative values) is created. See example below. height (default = "2ex") the height of the bar as a CSS measurement e.g. "1em ...

The gradient of the scalar potential (and hence also its opposite, as in the case of a vector field with an associated potential field) is everywhere perpendicular to the equipotential surface, and zero inside a three-dimensional equipotential region. Electrical conductors offer an intuitive example.
