阅读更多关于 [原创]FineUI秘密花园（六） — 表单控件

FineUI中有哪些常用的表单控件，它们有什么共同点和不同点，这一篇文章我们会详细解说。表单控件的公共属性所有的表单都具有如下属性： ShowLabel：是否显示标签（默认值：true）。 ShowEmptyLabel：是否显示空白的标签（默认值：false）。 Label：标签文本（默认值：""）。 LabelSeparator：表单中字段与标签的分隔符，可以通过Web.config、PageManager、Form三个级别进行控制，一般不需要设置此属性（默认值：PageManager中的设置参数）。 ShowRedStar：在标签后面显示红色的星号（用来标识必填项），一般与Required等表单验证属性配合使用。 Readonly：表单控件的只读状态（默认值：false）。 TabIndex：Tab按键的跳转顺序，一般不需要设置此属性，页面会根据控件的出现顺序自动决定Tab按键的跳转顺序（默认值：null）。 OffsetRight：距离右侧边界的宽度，可以通过Web.config、PageManager、Form三个级别进行控制，一般不需要设置此属性（默认值：PageManager中的设置参数）。 ToolTip：提示文本（默认值：""）。 ToolTipTitle：提示文本的标题（默认值：""）。 ToolTipAutoHide：是否自动隐藏提示信息（默认值：true）

Add NewLine to label's Text at design time

问题 How can I add newlines to a Label 's Text at design time? There are some posts on Stack Overflow on how to do this in code-behind, but there is no post about that for design time yet, it seems? 回答1: When you click on the label Text property in the Property window for the label, a drop down will appear in which you can, when you press Enter , go to the new line. I just tried it, and it works in Visual Studio 2010. Here's a screenshot to clarify: 回答2: Design Time \r\n will do the trick - label1

Assign IDs to Individual Axis Text Elements

阅读更多关于 Assign IDs to Individual Axis Text Elements

问题 I'm using d3.axis() to create axis labels and tick marks that I'd like to refer to individually using d3.select("#axisTextIDValue") but I see no way to manipulate the id attribute of individual text elements in an axis. Does anyone know how to create ID values for the ticks or text elements of an axis? 回答1: While the other answer does explain how to select the ticks, if you want to assign unique ids to generated elements like these, you can do so using subselections by giving an id or class

R: ggplot2: Adding count labels to histogram with density overlay

阅读更多关于 R: ggplot2: Adding count labels to histogram with density overlay

问题 I have a time-series that I'm examining for data heterogeneity, and wish to explain some important facets of this to some data analysts. I have a density histogram overlayed by a KDE plot (in order to see both plots obviously). However the original data are counts, and I want to place the count values as labels above the histogram bars. Here is some code: $tix_hist <- ggplot(tix, aes(x=Tix_Cnt)) + geom_histogram(aes(y = ..density..), colour="black", fill="orange", binwidth=50) + xlab("Bin") +

Add labels on lattice xyplot

问题 I have created a xyplot with lattice library(lattice) X1=c(5, -2, 1, -3) X2=X1^2 names=paste("dot", 1:4, sep="") xyplot(X2~X1, data=data.frame(X1, X2), pch=20, cex=1:4) Now I want to add a label (text) for each dot. The info is in names=paste("dot", 1:4, sep="") I have tried with no success the following panel.text(x=X2, y=X1, names) or, using directlabels library(directlabels) p=xyplot(X2~X1,data=data.frame(X1, X2), pch=20, group=names, cex=1:4) direct.label(p,smart.grid,FALSE) but I don't

how to avoid overlapping labels with identical data points in scatterplot / ggplot?

阅读更多关于 how to avoid overlapping labels with identical data points in scatterplot / ggplot?

问题 Is there any function etc which avoids overlapping data labels for identical data points in a scatter plot? I have checked the various questions/responses to textxy, direct.label, and geom_text(), but I haven't been successful. Maybe it's simply not possible. Here's a sample of the relevant data: structure(list(cowc = structure(c(5L, 7L, 24L, 24L, 23L, 36L, 34L, 38L, 23L, 6L, 8L, 38L, 38L, 23L, 5L, 7L, 24L, 24L, 23L, 36L, 34L, 38L, 23L, 6L, 8L, 38L, 38L, 23L), .Label = c("AFG", "ANG", "AZE",

Drawing multiple edges between two nodes with networkx

阅读更多关于 Drawing multiple edges between two nodes with networkx

问题 I need to draw a directed graph with more than one edge (with different weights) between two nodes. That is, I have nodes A and B and edges (A,B) with length=2 and (B,A) with length=3. I have tried both using G=nx.Digraph and G=nx.Multidigraph. When I draw it, I only get to view one edge and only one of the labels. Is there any way to do it? 回答1: Try the following: import networkx as nx import matplotlib.pyplot as plt G = nx.DiGraph() #or G = nx.MultiDiGraph() G.add_node('A') G.add_node('B')
