gradient

问题 I'm trying to apply an angle gradient to the dashes created with the code I've written inside a custom UIView class, as below. Although it needs tweaking, I'm happy with the results it produces so far. Given the input parameters in the view initialisation (below), and a frame of 768 * 768 on an iPad Air2 in portrait mode, it produces the following gauge: First gauge What I'd like to do is to cause each of the dashes to step through a user-defined gradient, e.g. green to red, much like this

问题 I cannot use Lollipop elevation property because I need to target devices from API 18. I need to place a shadow on the right and left side of a view. This is what I tried so far : <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <item> <shape > <!-- set the shadow color here --> <stroke android:width="2dp" android:color="#7000" /> <!-- setting the thickness of shadow (positive value will give shadow on

问题 I'm trying to do a bubble chart where the colors of the points are a gradient color depending on a value. The limit values I've set are 0.0001 to 0.1. The problem i have is that i want that the legend of color gradient have the same length from 0.0001 to 0.001, from 0.001 to 0.01, and from 0.01 to 0.1. The code I've wrote represents 0.5 in the middle of scale. I have this: x <- as.data.frame(cbind(c("rRNA modification","response to hydrogen peroxide","RNA processing","mRNA processing","rRNA

问题 I want to have two different gradients. Is this possible with two different palettes? And yes, how to declare them? 回答1: I guess the problem is that you don't set a fixed cbrange . The numerical values given in the set paletted defined statement are relative values. According to your previous questions you scale the color to the range [-1:1] . In that case, your relative values in the palette definition and those in the plots coincide. However, if you have only positive or only negative

问题 I am not sure how to exactly phrase this question so maybe that's why I can't find help with this. I am coding a webpage and the designer has made a background for a part of it. It's sort of a two way gradient: both horizontal and vertical at the same time. I am attaching the image here because I'm not sure how to explain it. I'm sorry if it's very obvious but I can't find anything resembling this anywhere. Thank you! Here's the image: EDIT: The question is, can I make this background using

问题 I am trying to replicate the functionalities of QGIS software in an Android application. I want to apply a color gradient (Red to Green lut) on an image for further efficient analysis. The image shown below is generated after applying the NDVI (Normalised Difference Vegetation Index) indicator on it. The value of NDVI ranges from -1 to +1. The image shown below is generated after applying the color gradient on it. This image now can be analysed efficiently because it shows the plants as green

问题 I have the following problem: Write a web page which has on top of it a rainbow built using gradient colors. The rainbow should be tilted with an angle (it should not be perfectly horizontal) and the width of the rainbow on the left side should be smaller than the width of the rainbow on the right side. I don't know how to do the part with the width. Can anyone help me? #grad1 { height: 200px; background: linear-gradient(45deg, red, orange, yellow, green, blue, indigo, violet); } <div id=
