How to add text on horizontal line with JavaFX BarChart

由 一曲冷凌霜 提交于 2019-12-12 02:36:54
问题 I use an extended class of BarChart to add vertical lines and text on top of bars. This works fine but I want to display a small text at the top right of the horizontal line. I tried this without success: public void addHorizontalValueMarker(Data<X, Y> marker) { Objects.requireNonNull(marker, "the marker must not be null"); if (horizontalMarkers.contains(marker)) return; Line line = new Line(); line.setStroke(Color.RED); marker.setNode(line); getPlotChildren().add(line); // Adding a label

Using a line to divide a canvas into two new canvases

由 核能气质少年 提交于 2019-12-12 00:47:11
问题 I'm looking to allow users to slice an existing canvas into two canvases in whatever direction they would like. I know how to allow the user to draw a line and I also know how to copy the image data of one canvas onto two new ones, but how can I copy only the relevant color data on either side of the user-drawn line to its respective canvas? For example, in the following demo I'd like the canvas to be "cut" where the white line is: const canvas = document.querySelector("canvas"), ctx = canvas

问题 I'm trying to make a web page, where people can click on two objects and it creates a line between those two. But I want to go further on and be able to connect the last one with another one.

return entire line when search string is found

由 限于喜欢 提交于 2019-12-11 22:24:52
问题 I want to return the whole line when I find the search string in the line. I'm getting most of what I need when I print but I'm short about 10 characters. I get the start of the line and the string and about 10 characters after that but nothing more. Here's my code (thanks in advance): use strict; use warnings; my $calls_dir = "Ask/"; opendir(my $search_dir, $calls_dir) or die "$!\n"; my @files = grep /\.txt$/i, readdir $search_dir; closedir $search_dir; print "Got ", scalar @files, " files\n

CombineGeometry between an Ellipse and a Line getting no intersection

由 做~自己de王妃 提交于 2019-12-11 20:13:34
问题 So I tested this code (intersection between two ellipses, look at the accepted answer), but if I change one of the ellipses to a line geometry (or path geometry representing a line) and it gives me no intersection. Does any one know why? Does combine geometry work on area of the geometry, and since lines have no area, it gives no intersection? Since eventually I would want to see if the arbitrary path geometries intersect. I guess I would have to find a way to "pad" the path with some area,
