Drawing Multiple Functions on the Same Graph. the x axis is the same for all 70 data sets, it is only y that changes from data set to data set. I have a matlab function that contain some constant parameter, I want to draw that function, on say same figure, using hold on (probably) while changing the value of that constant. If I select one object from my list, I can still plot it. I'm pulling the coordinates (x,y,z) from a 1x22 structure. 1. All the applicants will feel free to learn the MATLAB Questions with the help of this article. I know there is a 'NextPlot' property for UIAxes, but it doesn't work when plotting patch.

Plotting machine learning features with Matlab. setp works transparently with a list of objects or a single object. Plotting multiple box-plots on the same canvas. Someone above stated happily that this answer is still helping people years after it was asked, too me this is just sad, that Mathworks haven't improved this in all of that time. They allow users to very quickly create customized data visualizations and displays. Basic plotting is relatively straightforward, but MATLAB has more sophisticated features that give the user control over most of the plot details. I'm not sure how you'd detect what the color was if you didn't save the handle to the colored line you plotted, but maybe there is a way by using findobj() and seeing if you can get the color of any line object as a property. 0. so what i would like to do is assign z = 1 for the first curve, z = 2 for the second curve ects. plotting a linear equation. data1 and data2 do not need to be the same length, as the syntax you have shown will simply plot the data against the index.
