pie-chart

I would like to know how to format the data labels on a Pie Chart so it shows max 2 decimal characters, and never shows trailing zeros , for example: 2 -> 2 2.0 -> 2 2.566 -> 2.57 In other words, I am asking how to set dataLabelFormatString parameter ? I know it is using sprintf , thus I tried '%.2f' and '%g'. They do not solved my problem though. Since the first makes each number to show to decimal characters, the other just removes trailing zeros but doesn't work with precision as in this case the digits you place in front of it ,e.g. '%.2g' refer to the total length of the character. I do

I already post two question related this (plz refer this custom piechart 1 and this custom pie chart 2 ) but not getting answer ,finally i develop my own but getting stuck at some point . I need to create lines between drawn area as you can see in image .for inner circle i used canvas.drawArc() .for outer circle i used canvas.drawCircle() and for middle lines i used canvas.drawBitmap() method with differ angle .here inner and outer circle drawn properly but for middle arc ,only first two bitmap/arcs are drawn properly but remaining two are not in their exact position . I used same code for

I would like to stack two pie charts ontop each other. The idea here is then to make one of them smaller so you only can see a outer ring of the pie chart behind. I tried using: chartCalProgres.BackColor = Color.Transparent; chartCalProgres.ChartAreas[0].BackColor = Color.Transparent; But as you can see in the link below, it did not work. Anyone have an idea to how this effect could be achieved? Pie Charts Should look like this This is not possible with Pie charts, but you can get it done rather nicely with the ChartType.Doughnut: Here are the steps: 1 We need to have two Series and two

I tried displaying a tooltip for each "slice" of a PieChart similar to this in chart.js: I found this answer basically trying to achieve the same in the same framework. It has two upvotes and the same seemed to work on other chart types judging by other (accepted) answers. However the code would not really work for me in the sense that there was no tooltip showing up. Example code showing the problem: import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.chart.PieChart; import javafx.scene.control.Button; import javafx.scene.control.Tooltip; import javafx.scene

I am trying to set a circular avatar of a player of a game with a piechart representation on the avatar's circular border. Player 1 - Wins 25% Lost 70% Drawn 5% cell.selectedPhoto.frame = CGRectMake(cell.selectedPhoto.frame.origin.x, cell.selectedPhoto.frame.origin.y, 75, 75); cell.selectedPhoto.clipsToBounds = YES; cell.selectedPhoto.layer.cornerRadius = 75/2.0f; cell.selectedPhoto.layer.borderColor=[UIColor orangeColor].CGColor; cell.selectedPhoto.layer.borderWidth=2.5f; cell.selectedBadge.layer.cornerRadius = 15; I have the UIImageView as a circle already with a single border colour. At

I am trying to arrange two pie charts in a single row using the subplot function from the plotly package but the resultant plot is not what I expect. I was able to do the same for line charts, etc but I am facing trouble plotting two pie charts in a single row. Following is the code that I have. ds_r <- data.frame(labels = c("Baseline", "DTC", "Detailing", "Flex"), values = c(63.5, 8.5, 20.6, 7.4)) ds_l <- data.frame(labels = c("Baseline"), values = c(100)) plot_right <- plot_ly(ds_r, labels = labels, values = values, type = "pie") %>% layout(title = "Sales - Decomposed") plot_left <- plot_ly
