Lexis diagram showing the cohort of 2003-born persons in green, and the year 2005 in red. In demography a Lexis diagram (named after economist and social scientist Wilhelm Lexis) is a two dimensional diagram used to represent events (such as births or deaths) that occur to individuals belonging to different cohorts. Calendar time is usually ...
A ternary flammability diagram, showing which mixtures of methane, oxygen gas, and inert nitrogen gas will burn. A ternary plot, ternary graph, triangle plot, simplex plot, or Gibbs triangle is a barycentric plot on three variables which sum to a constant. [1] It graphically depicts the ratios of the three variables as positions in an ...
Run sequence plots [1] are an easy way to graphically summarize a univariate data set. A common assumption of univariate data sets is that they behave like: [2] random drawings; from a fixed distribution; with a common location; and; with a common scale. With run sequence plots, shifts in location and scale are typically quite evident.
A sample burndown chart for a completed iteration. It will show the remaining effort and tasks for each of the 21 work days of the 1-month iteration. A burndown chart or burn-down chart is a graphical representation of work left to do versus time. [1] The outstanding work (or backlog) is often on the vertical axis, with time along the horizontal.
A Wardley map is a map for business strategy. [1] Components are positioned within a value chain and anchored by the user need, with movement described by an evolution axis. [2] Wardley maps are named after Simon Wardley who created the technique at Fotango in 2005 having created the evolutionary framing the previous year.
Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ″ = 1′ 0″). Site plans are often drawn at 1:200 or 1:100. Scale is a nuanced subject in the use of engineering drawings.
More technically, the abscissa of a point is the signed measure of its projection on the primary axis. Its absolute value is the distance between the projection and the origin of the axis, and its sign is given by the location on the projection relative to the origin (before: negative; after: positive). Similarly, the ordinate of a point is the ...
From Figure 8, the intersection of 1 / β and A OL occurs at f 0 dB = 1 kHz. Notice that the peak in the gain A FB near f 0 dB is almost gone. [note 2] [9] Figure 9 is the phase plot. Using the value of f 0 dB = 1 kHz found above from the magnitude plot of Figure 8, the open-loop phase at f 0 dB is −135°, which is a phase margin of 45 ...
