本文介绍了我如何有条件地在matlab中的散点图上的点颜色?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我试图在一组数据上绘制一个绘图(使用散点图或绘图)。 我有一个数据数组,其中包含的值。 我还有一个置信数组,它包含从0到1的值,表示该值的可靠性。 在我的散点图中,我必须用不同的颜色绘制置信度低于0.5的值。I am trying to draw a plot (using scatter or plot) on a set of data.I have a data array which contains the values. I also have a confidence array which contains values from 0 to 1 to indicate how reliable that value is.In my scatter plot I have to plot the values which have confidence lower than 0.5 in a different colour.到目前为止,我有:for i=1:length(data) if confidence(i) < 0.5 colour(i) = 'g'; else colour(i) = 'b'; endendf = figure;scatter(xvalues,data,[],colour,'x'); 问题: 我希望有绿色和蓝色的x,但情节显示全部蓝色。 我检查了有信心值,肯定低于0.5。 我不知道如何指定颜色。I expect there to be green and blue x's but the plot shows all blue.I have checked that there are confidence values which are definitely lower that 0.5.I am not sure how else to specify the colours.我使用Matlab R2013a。I am using Matlab R2013a.感谢您的帮助。推荐答案您应该简单地绘制两次,使用 c $ c>命令:You should simply plot twice, using the hold on command:data = rand(10,1);confidence = rand(10,1);xvalues = rand(10,1);f = figure; hold on;scatter(xvalues(confidence<0.5),data(confidence<0.5),'g');scatter(xvalues(confidence>=0.5),data(confidence>=0.5),'b'); $ b confidence 以查看它的功能)。此外,对于将来,如果你的代码是一个独立的MWE(最低工作示例),它是非常有用的。这意味着也产生一些数据点,所以其他人可以直接复制/粘贴和运行你的代码:)。Also, for the future, it's very useful if your code is a self-contained MWE (minimum working example). This means also generating some data points, so other people can just copy/paste and run your code directly : ). 这篇关于我如何有条件地在matlab中的散点图上的点颜色?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
