问题 The application is a GUI designed with GUIDE with lots of subplots that have an refresh interval approx ~1s adding new data to the time series, for example: I have read through making-graphs-responsive-with-data-linking, but the efficient linkdata on does not work in standalone applications when exporting with application compiler: Error using linkdata (line 24) Plots cannot be linked in deployed applications because linked plots require the MATLAB workspace. ,while refreshdata works but

问题 I am developing an application in C# and there is a requirement of the form of the main window in rounded rectangle or some times triangle type or round shape. so, how can I achieve this kind of features in C# 2008 回答1: I think this is what you're looking for: http://www.codersource.net/csharp_custom_window_forms.aspx Also you can google for it, there are plenty examples. 回答2: Assuming this is on Windows Forms you can check these two articles on MSDN: http://msdn.microsoft.com/en-us/library

问题 I'm trying to maintain and then use a transformation matrix for a computer graphics program. It's a 3x3 matrix that stores scale, rotate, and translate information for (x,y) points. My program can handle any individual case... i.e. if I only scale or only rotate it works fine. However, it does not seem to work when combining scale and rotate, and I think that has to do with how I combine rotation and scale in the code. The matrix is called transformation and is of type float. The following

问题 I'm trying to teach myself java and I "try" to code a little game. I have a problem and I guess the solution is very simple but I'm struggling. The basic idea is that I am controlling a circle and I want to spawn circles every 5 seconds at random locations within the boundries of my window . The circles should move towords the location of the circle that I'm controlling. Here's what I have so far: Window-Class: package TestGame; import java.awt.Graphics; public class Window extends GameIntern

问题 I have a difficulty with texturepacker2 from libgdx . I was trying to create textureAtlas using texturepakcer2 so that I can create animated images. However I could not use TexturePacker2.process(Input Directory Path", "Output Directory Path", "texture_file"); Because it could not recognize TexturePacker2. Even thought I import gdx-tool.jar file inside libs and also added libraries through Project -> Properties -> Java Build Path -> Libraries -> Add jars , it still cannot resolve nor

问题 I'll like to make an Oval move from one place to the other in a JPanel when a button is clicked. This is the code I came up with. When I click the button however it all happens at once without visible movement the slow from the start to finish seen. The Oval just appears in a new location. import java.awt.Color; import java.awt.Graphics; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; import javax.swing.JPanel; public class testtest implements

问题 I have a problem with opening a new graphics device to make a new plot. The code is like: par(mfrow = c(1, n.groups),pty="s") if (n.groups == 3){ par(mfrow = c(2, 2) ) } else if (n.groups == 5 | n.groups == 6) { par(mfrow = c(3, 3)) } QQ <- tapply(data$Measurement,data$Group,qqnorm,plot.it=T, main = "Q-Q Plot") ... some other lines ... grp.plot <- ggplot(group.join, aes(x=Group,y=mean)) + geom_bar(stat="identity") box.plot <- ggplot(data = brcp.df, aes(x = Group, y = Measurement)) + geom

问题 I am trying to move the blue square around the grid by pressing the arrow keys. I already set up the KeyListener but when I repaint the frame, I have to move the frame around in order for it to update. How do I make it a smooth animation (moving the square from one coordinate to another)? Example: if (keyCode == KeyEvent.VK_LEFT){ x5=x5-xChange; frame.repaint(); } My images are buffered images and are all set to specific coordinates. Here is my graphics class: public static class

问题 So I have a cube that I wish to rotate around any of its three axes (the axes of the cube, not the window). As many other similar questions have stated, my rotations work as long as I am only rotating in one direction, but when I start mixing them, I get strange results. In particular, the rotation about the y-axis always rotates about the y-axis of the window, regardless of how the cube has been rotated. My drawing code is as follows: glMatrixMode(GL_MODELVIEW) ; glLoadIdentity(); gluLookAt

问题 I'm using graphics.h in order to start with a bit of graphic in C++, but when I run the code the program crash. I'm using CodeBlocks as a compiler and Windows 8.1 as an operating system. What should I do in order to make it works? Here is the code: #include <graphics.h> int main() { int gd = DETECT; int gm; initgraph(&gd, &gm, "C:\\TC\\BGI"); arc(200, 200, 0, 130, 50); getch(); closegraph(); } 回答1: "What should I do to make it works?" 1) Forget about graphics.h it is obsolete. 2) Get yourself
