percentage

问题 I need to assign a fixed width to a few columns of a JTable and then an equal width to all the other columns. Suppose a JTable has 5 columns. The first column should have a width of 100 and the second one a width of 150. If the remaining width of the JTable is 600 after setting the width of the two columns, I'd like to evenly split it among the other three columns. The problem is table.getParent().getSize().width is often 0, even if it is added to the JFrame and visible, so I can't use it as

问题 Below, I have R code that plots a likert plot. set.seed(1234) library(e1071) probs <- cbind(c(.4,.2/3,.2/3,.2/3,.4),c(.1/4,.1/4,.9,.1/4,.1/4),c(.2,.2,.2,.2,.2)) my.n <- 100 my.len <- ncol(probs)*my.n raw <- matrix(NA,nrow=my.len,ncol=2) raw <- NULL for(i in 1:ncol(probs)){ raw <- rbind(raw, cbind(i,rdiscrete(my.n,probs=probs[,i],values=1:5))) } r <- data.frame( cbind( as.numeric( row.names( tapply(raw[,2], raw[,1], mean) ) ), tapply(raw[,2], raw[,1], mean), tapply(raw[,2], raw[,1], mean) +

问题 I have 5 items in total, and I would like to calculate percentage based on [data] filed. The result will be used for pie chart. Array ( [0] => Array ( [label] => Item1 [data] => 849 ) [1] => Array ( [label] => Item2 [data] => 657 ) [2] => Array ( [label] => Item3 [data] => 571 ) [3] => Array ( [label] => Item4 [data] => 538 ) [4] => Array ( [label] => Item5 [data] => 446 ) ) Using: (5/[data])*100 does not produce correct result, and I'm not sure how to perform proper calculations. 回答1: I

问题 I am trying to simply format a number as a percent with two decimal places. If it is 37 divided by 38 (aka .973684210526315789), I would like it to show 97.36 % in the SQL output. I know it is recommended to do formatting in the Application, however this is for an automated export. This is using SQL Server 2008. Here is what I have now: select CONVERT(VARCHAR(50),cast(37 as decimal)/cast(38 as decimal)*100)+' %' AS [%] If you could explain what the various parameters are as well in any

问题 I would like to be able to get the percentage of each row with relation of the whole total. Here is my formula: =COUNTDISTINCT(Fields!ID.Value, "NameOfRowGrouping") / COUNTDISTINCT(Fields!ID.Value, "TopLevelGroupName") The percentage it comes out is the percentage between row total and total of each group: Group Qty % --------------------- Group 1 MemberA 3 40% MemberB 4 60% Total 7 Group 2 MemberC 2 50% MemberD 2 50% Total 4 Grand Total 11 I need to know the percentage with relation of the

问题 How can this compilable minimal code snippet example, which uses JFreeChart as plotting API, adapted in order to show both absoulte values AND percentages ? I couldn't extract this information neither from any code snippet on the internet nor from the JFreechart manual itself. The code snippet produces a pie chart showing only percentages. The absolute values in my case also matter, so i need to display them right under the percentages. Here is the code: (Note it lacks the imports) public

问题 I have a main container div, and I'd like it to be margined from the top of the screen exactly, for example, 10% of the screen width. This way I won't have problems with non-uniform screen sizes etc.. I already found a dirty workaround which is putting a 1px by 1px image of the color of the background, right before the div, and then style it to have 10% of the width of the screen. But this looks quite dirty, doesn't it? Is there any better solution? 回答1: The solution I find very elegant is to

问题 Can this equation be reworked to a correctly formatted string? Dim Total = MyNumber / 100 * MyVAT Produces error: "Input string was not in a correct format" 回答1: You should really set Option Strict to on . Then this would never compile since MyNumber is a string(as you've commented). You should first ensure that the input is numeric, for example with Decimal.TryParse : Dim Total As Decimal Dim num As Decimal If Decimal.TryParse(MyNumber, num) Then Total = num / 100 * MyVAT End If Now you can
