![]() The table below lists all available projection types, samples can be found after the table. Available ProjectionsĪs far as An圜hart constantly implements new features to improves An圜hart charting library, all new projections in further versions would be added MapProjections enum along with existing ones. Possible string values for the projection are listed in enum. ![]() Add Charts to Our JavaScript App with Anychart is published by. Snippet above shows a string as a parameter for crs() method. Anychart is an easy to use library that lets us add chart into our JavaScript web app. To set map projection you should set its type using the crs() method: var map = anychart.map() This feature can come in particularly handy when you need to create a custom map with small regions or a region located in high/low latitudes. parent, id ) or map custom fields, see the Mapping section. Important: not only you can change the projection of a map, you can also change projection of any selected region (feature) using featureCrs() method, see Changing Region projection section for this. If your data is a CSV string, you should pass a CSV mapping object as the second parameter. Since many purposes exist for maps, so do many projections exist upon which to construct them.Īn圜hart allows to display any map in several projections, below you will find the list of all available projections with map samples.ĭepending on your visualization task you can choose what projection to use in your project or give end-user an ability to swap projections in real-time. The purpose of the map, then, determines which projection should form the base for the map. Each projection preserves or compromises or approximates basic metric properties in different ways. Map projections can be constructed to preserve one or some of map regions properties (area, shape, direction, bearing, distance, scale), though not all of them simultaneously. The term "projection" here refers to any function defined on the earth's surface and with values on the plane, and not necessarily a geometric projection.įlat maps could not exist without map projections, because a sphere cannot be laid flat over a plane without distortions. Triple Exponential Moving Average (TRIX)Ī map projection is any method used in cartography to represent the two-dimensional curved surface of the earth or other body on a plane.Moving Average Convergence Divergence (MACD).
