浏览器调用Favicon的原则是首先在网页所在的目录下寻找Faviconico文件,如果没有,便到网站的根目录下寻找。因此,在网页中使用Favicon最简单的法便是将制作好的图标文件命名为Faviconico,然后将其上传到网站的根目录即可。如果您需要将Faviconico放到其他目录下,或者希望让不同的网页显示不同的Favicon,就需要在网页Html文件中做设定了,具体设置也很简单,在Html中的<head>部分加入如下的代码:程序代码:Firefox还支持GIF动画格式的Favicon,使用方法如下:首先制作一个1616的gif动画,然后在html代码中加入如下代码:程序代码
JSONstringify之前数据就不对吧,
sendJsonexperimentParam[paramName[i]] = parseFloat(paramValue[i]);应该是
sendJsonexperimentParamparamName[i]= parseFloat(paramValue[i]);
xData也是,存的格式是对象的不能用push
本文中介绍了几种常见的利用 plotly_express 作图方法的参数
In a scatter plot, each row of data_frame is represented by a symbol mark in 2D space
In a 2D line plot, each row of data_frame is represented as vertex of a polyline mark in 2D space
In a polar line plot, each row of data_frame is represented as vertex of a polyline mark in polar coordinates
In a stacked area plot, each row of data_frame is represented as vertex of a polyline mark in 2D space The area between successive polylines is filled
在堆叠的面积图形中,每行的DF数据代表多边形的最高点。
In a bar plot, each row of data_frame is represented as a rectangular mark
在柱状图中,每行的DF数据代表一个矩形
In a polar bar plot, each row of data_frame is represented as a wedge(楔形) mark in polar coordinates
In a violin plot, rows of data_frame are grouped together into a curved(弯曲的) mark to visualize their distribution(分布)
In a histogram, rows of data_frame are grouped together into a rectangular mark to visualize the 1D distribution of an aggregate function histfunc (eg the count or sum) of the value y (or x if orientation is 'h')
In a pie plot, each row of data_frame is represented as a sector of a pie
In a choropleth map, each row of data_frame is represented by a colored region mark on a map
通常在地图中使用
In a density heatmap, rows of data_frame are grouped together into colored rectangular tiles to visualize the 2D distribution of an aggregate function histfunc (eg the count or sum) of the value z
参数解释以第一个散点图为例:
其他作图方法的作图参数类似
java获取微信的openid的方法是根据授权code来获取的,方法如下:一个Servlet请求获取code:/根据code取得openId@paramappid公众号的唯一标识@paramsecret公众号的appsecret密钥@paramcodecode为换取access_token的票据@return/publicvoiddoPost(>
一 express框架接收
appget('/',function(req,res) { var url = reqqueryurl; var name = reqqueryname; consolelog(url, name);});
二 接收Get
1 get参数在requrl上
2 使用urlparse将数据由字符串转变为obj
indexjs:
var >
