Webpage heatmap js and heatmap js
Using HBuilder + js to implement webpage heat map
Let's talk about the code.

For the heatmap. min. js used in the code, search for heatmap to download it.
/** Heatmap. js v2.0.0 | JavaScript
Heatmap. js v2.0 hotspot map plug-in uses the demo example, heatmap. jsdemo
Heatmap. js is currently the most widely used hotspot map plug-in. Its implementation principle is to use canvas to plot the region of the hotspot map. Therefore, heatmap can only be used in browsers that support html5.

alignment.The labels represents the label, which is null by default and represents the original name of the variable. Labels=f: Indicates that the label is not displayed.Example Introduction:Special case USAGE:When clustering with a known distance matrix, the distance between the variables has been calculated, just want to useA known distance matrix is clustered. At this point, you need to turn the distance matrix into the dist type.Then perform hclust () clustering and plot () drawing.#MyData
In bioinformatics, R is often used for drawing, while R is very powerful in drawing heatmap. In general, I used to use the heatmap.2 function in the gplots package for drawing. However, this function cannot adjust the clustering analysis (clustering) method. Therefore, you can use different clustering analysis methods to integrate heatmap by writing a small piece
Use the Heatmap plugin in an ArcGIS for JS API environment.Because the latest heatmap does not provide for ARCGISJSAPI plug-ins, too lazy to study the new version of the code, so here is the old version of the heatmap.However, the old version of the plugin has a problem, that is, when the point aggregation calculation is grouped according to the original coordinate points, which causes when the coordinate v

It is a very common requirement to use sample points to make heat force diagrams. The Heat force diagram can give the map reader intuitive information, and here's a look at how to make a nice heatmap in ArcGIS Pro.1.Getting the sample data ready is, of course, much better. I use the global seismic point data, which has about 21w+ data volume. Data like this can be obtained from a number of websites that provide public data, such as the USGS.2.Using th

The setTimeout and setInterval of JavaScript are two methods that can easily fool others' feelings, because we often start to think that the call will be executed in the established way. I think many people share the same feeling. For example
The Code is as follows:
SetTimeout (function () {alert ('Hello! ');}, 0 );SetInterval (callbackfunctions, 100 );
It is assumed that the greeting method in setTimeout will be executed immediately, because it i
Personal Summary:1.webassembly Introduction: Webassembly is an efficient, low-level bytecode for developing network applications. Allows languages other than JavaScript (such as C,c++,rust and other) to be used in Web applications to write applications and then compile (early) WebAssembly.This is the sixth chapter of how JavaScript works.Now, we'll dissect how WebAssembly works, and most importantly, its pe

Sometimes we need to trigger an event without returning a value during js writing, so we may need to write href = "#", which contains a location information. the default anchor is # top, that is, the top of the Web page. When you click this link continuously and quickly, the browser slows down or even crashes.
Of course, we generally use three href = "###", but after reading this article, we can use javascript:; (a colon and a semicolon)
