Heat map Wikipedia.A heat map or heatmap is a graphical representation of data where the individual values contained in a matrix are represented as colors.The term heat map was originally coined and trademarked by software designer Cormac Kinney in 1.D display depicting financial market information,1 though similar plots such as shading matrices have existed for over a century.HistoryeditThe company that acquired Kinneys invention in 2.Heat maps originated in 2.D displays of the values in a data matrix.D Contour Plot Free Software' title='2D Contour Plot Free Software' />Free Statistical Software This page contains links to free software packages that you can download and install on your computer for standalone offline, nonInternet.Larger values were represented by small dark gray or black squares pixels and smaller values by lighter squares.Loua 1.Paris.Sneath 1. Jacques Bertin used a similar representation to display data that conformed to a Guttman scale.The idea for joining cluster trees to the rows and columns of the data matrix originated with Robert Ling in 1.Ling used overstruck printer characters to represent different shades of gray, one character width per pixel.Leland Wilkinson developed the first computer program in 1.SYSTAT to produce cluster heat maps with high resolution color graphics.The Eisen et al.SYSTAT design.There are different kinds of heat maps Web heat maps have been used for displaying areas of a Web page most frequently scanned by visitors.Web heatmaps are often used alongside other forms of web analytics and session replay tools.Biology heat maps are typically used in molecular biology to represent the level of expression of many genes across a number of comparable samples e.DNA microarrays.The tree map is a 2.D hierarchical partitioning of data that visually resembles a heat map.A mosaic plot is a tiled heat map for representing a two way or higher way table of data.As with treemaps, the rectangular regions in a mosaic plot are hierarchically organized.The means that the regions are rectangles instead of squares.Friendly 1.A density function visualization is a heat map for representing the density of dots in a map.It enables one to perceive density of points independently of the zoom factor.Perrot et al 2.Spark and Hadoop.Colour schemeseditThere are many different color schemes that can be used to illustrate the heatmap, with perceptual advantages and disadvantages for each.Rainbow colormaps are often used, as humans can perceive more shades of color than they can of gray, and this would purportedly increase the amount of detail perceivable in the image.However, this is discouraged by many in the scientific community, for the following reasons 67891.The colors lack the natural perceptual ordering found in grayscale or blackbody spectrum colormaps.Common colormaps like the jet colormap used as the default in many visualization software packages have uncontrolled changes in luminance that prevent meaningful conversion to grayscale for display or printing.This also distracts from the actual data, arbitrarily making yellow and cyan regions appear more prominent than the regions of the data that are actually most important.The changes between colors also lead to perception of gradients that arent actually present, making actual gradients less prominent, meaning that rainbow colormaps can actually obscure detail in many cases rather than enhancing it.Choropleth maps vs.Choropleth maps are sometimes incorrectly referred to as heat maps.A choropleth map features different shading or patterns within geographic boundaries to show the proportion of a variable of interest, whereas the coloration a heat map in a map context does not correspond to geographic boundaries.Software implementationseditSeveral heat map software implementations are listed here the list is not complete Permut.Matrix is a work space designed to graphically explore numerical datasets.It offers several methods for the optimal reorganization of rows and columns of a numerical dataset.Neo.Vision Hypersystems, Inc., a software firm founded by Cormac Kinney, and funded by Intel and Deutsche Bank, developed Heatmaps depicting real time financial data and calculations, which were licensed to over 5.Neo.Vision Heatmaps became a feature on nasdaq.R, a free software environment for statistical computing and graphics, contains several functions to trace heat maps1.Gnuplot, a universal and free command line plotting program, can trace 2.D and 3.D heat maps1.The Google Docs spreadsheet application includes a Heat Map gadget, but for country wise data only, not for general matrix data.Dave Greens cubehelix colour scheme provides resources for a colour scheme that prints as a monotonically increasing greyscale on black and white postscript devices1.Origin, a graphing and data analysis software can generate heat maps from data in a matrix, or a virtual matrix in a worksheet.Qlucore includes a heat map that is dynamically updated when filter parameters are changed.The ESPN Gamecast for soccer games uses heat maps to show where certain players have spent time on the field.Microsoft Excel can be used to generate heat maps using the Surface Chart.Though the default color range for Surface Charts in Excel is not conducive to heat maps, the colors can be edited to generate user friendly and intuitive heat maps.Sightsmap is a sightseeing popularity heatmap overlaid on Google Maps, based on crowdsourcing the number of Panoramio photos taken at each place in the world.Maptitude is business mapping software that includes a variety of customizable heat mapping tools and can use external data such as Excel files to show the results on geographic maps of your location.Heat.Map Builder is a standalone application for generating heatmaps of genomic microarray data developed at the Ashley Lab at Stanford.Littlstar provides a heatmap service for 3.Virtual Reality.Highcharts, a Java.Script charting library, provides the ability create heatmaps as a part of its solution.The Change Compass2.ExampleseditGeographical heat map of ocean salinity, using a rainbow colormap.Lake effect snow weather radar information is usually shown using a heatmap.Choropleth heatmap showing election results by municipality.Human voice visualized with a spectrogram a heat map representing the magnitude of the STFT.An alternative visualization is the waterfall plot.Example showing the relationships between a heat map, surface plot, and contour lines of the same data.Combination of surface plot and heatmap, where the surface
