fill

问题 I am using MATLAB to plot two lines of a time series... (a min and max line) I have the points converging at a single point at the end of the data. I am trying to fill the area in between the lines and then plot other lines on top of the shaded area. Here is my problem: When I use "fill" it does exactly what I want it to do...but it draws a line from the last point of the data back to the initial data point. How do I get rid of it? Here is a very vague sketch of my 2 examples: The line below

问题 I'm trying to make a website where an image is drawn on Canvas, then later the user is able to press a button to ctx.fill() certain parts of it with color. I'm running into issues where I can only ctx.fill() the most recently created shape which often isn't the shape I want. Here's an example. In this code (live at http://build.rivingtondesignhouse.com/piol/test/) I'm trying to draw the first rectangle, then save() it on the stack, then draw the second rectangle (and don't save it), then when

问题 I created the following 3d plot in MATLAB using the function plot3 : Now, I want to get a hatched area below the "2d sub-graphs" (i.e. below the blue and red curves). Unfortunately, I don't have any idea how to realize that. I would appreciate it very much if somebody had an idea. 回答1: You can do this using the function fill3 and referencing this answer for the 2D case to see how you have to add points on the ends of your data vectors to "close" your filled polygons. Although creating a

问题 Redesigning my website, in my CSS I have a div of height: 200px; then an image under it with a height: 532px; then lastly a div of height: 100%;. The last div is not filling the rest of the page, is there something I'm doing wrong? P.S. - All divs are in a container. All containing divs have height: 100%; I have since changed it, so I no longer require this. 回答1: First, you need to set the height of html and body to 100%. Then if you want to cover the rest of the page with that div you should

问题 I want to compute the distance of cells from a destination cell, using number of four-way movements to reach something. So the the four cells immediately adjacent to the destination have a distance of 1, and those on the four cardinal directions of each of them have a distance of 2 and so on. There is a maximum distance that might be around 16 or 20, and there are cells that are occupied by barriers; the distance can flow around them but not through them. I want to store the output into a 2D

问题 I have a 3 column layout with some details below the columns. You will notice that one of the column's height is greater than the others'. I'd like the other two divs to automatically fill the remaining space (up to the blue div). The text will be loaded dynamically so I need this to work with any column being larger (and by an arbitrary amount). Can this be done with HTML/CSS or do I have to use some JavaScript? HTML code (relevant part of it): <div id="content"> <div id="iconsHolder"> <div

问题 I have this tiny problem with a chart I am working on. I'd like to fill the area between 2 semi-vertical lines as shown below (teal and grey ones): However, when I use the following code, I don`t get anything: plt.fill_between(x, y_1, y_2, facecolor = 'red') What am I doing wrong? Kind regards, Greem 回答1: The data ranges of the x variable of both lines are completely seperate, so there is not even a single point at which a fill could be done in y direction. You may want to fill in x direction

问题 I would like to fill the transparent part of an image with another image in iOS. I have tried some stuff with UIGraphicsContext , but I can't get it working because I've never used that before. Here is the image: Some code I tried: UIImageView *v = [[UIImageView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; UIGraphicsBeginImageContextWithOptions(v.frame.size, YES, 0); CGContextRef context = UIGraphicsGetCurrentContext(); // beach image UIImage *img = [UIImage imageNamed:@"zivogosce

问题 I wanted to animate a the text fill with CSS. The Text should be filled with color from left to right. this is my CSS: .box-with-text { background-image: -webkit-linear-gradient(right, crimson 50%, white 50%); background-repeat: repeat; background-position: 0 0; background-size: 200% 100%; -webkit-text-fill-color: transparent; -webkit-background-clip: text; -webkit-animation: stripes normal forwards ease-in-out; animation: stripes 2s normal forwards ease-in-out; } Now only the first letter is

问题 I have a plot created in ggplot2 that uses scale_fill_gradientn . I'd like to add text at the minimum and maximum of the scale legend. For example, at the legend minimum display "Minimum" and at the legend maximum display "Maximum". There are posts using discrete fills and adding labels with numbers instead of text (e.g. here), but I am unsure how to use the labels feature with scale_fill_gradientn to only insert text at the min and max. At the present I am apt to getting errors: Error in
