Ett stolpdiagram har tal längs den vågräta axeln Vi ska prata om fyra olika typer av diagram: Stapeldiagram, stolpdiagram, cirkeldiagram och linjediagram.
Därför är det vanligt att redovisa tabeller och information med diagram. Människor tycker om färger och bilder.

Thus, if the random variable X is log-normally distributed, then Y = ln( X ) has a normal distribution Log-log plot - Wikipedi In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. R134a R404A R407C R410A R717 R744 R507 > In science and engineering, a semi-log plot/graph or semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale.It is useful for data with exponential relationships, where one variable covers a large range of values, or to zoom in and visualize that - what seems to be a straight line in the beginning - is in fact the slow start of a logarithmic curve that is. This page shows log P/h diagrams for the following refrigerants: R22 R134a R404A R407C R410A R717 (Ammonia) R744 (Carbon dioxide) R507 R22. Dessutom förenklar det identifiering av hur väl datamängden följer linjära, exponentiella, logaritmiska eller potens-funktioner, och upattning av funktionens parametrar The log P/h diagrams on this page can be retrieved from the Coolpack program, which can be downloaded here. Logaritmiska diagram Genom att logaritmera en eller båda axlarna i en graf kan man illustrera en datamängd som varierar mellan mycket små och mycket stora värden i ett och samma diagram. Thus moving a unit of distance along the scale means the number has been. Rather, the numbers 10 and 100, and 60 and 600 are equally spaced. Such a scale is nonlinear: the numbers 10 and 20, and 60 and 70, are not the same distance apart on a log scale. Monomials - relationships of the form y = a x k - appear as straight lines in a log-log graph, with the power term corresponding to the slope, and the constant term corresponding to the intercept of the line A logarithmic scale is a way of displaying numerical data over a very wide range of values in a compact way-typically the largest numbers in the data are hundreds or even thousands of times larger than the smallest numbers. In science and engineering, a log-log graph or log-log plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes.
