So, My question is asking me to plot the points (omega_d, M(omega_d)). These points represent the maximum gain for each damping factor 'd'. The first two input arguments to the text function specify the position. @b-fg There are many reasons why you might want new points attached to an existing curve, instead of one new scatter per new point… I have a scatter plot that marks points (ex: T=[5 10 100 1000 10000]; I want to add a vertical line for each point marked on the plot but I do not want to add each line manually. As you can tell, it becomes hard to work with them downstream in your code. It turns out that adding this dummy plot still causes the left axis to change. Preserve existing axes and plot, add a second axis with the new data. – b-fg Dec 5 '18 at 11:37. geoshow lat latitude lon longitude mapping maps plots shapefile. Hello, I wanted to add dots at the min, max points on the triangular plot that I have generated so that my final plot can look like this: Here is the code that I have so far: ts=0.1; i used plot3 command it just put points on the plot, i need to connect this point with mesh surface as stems extended from mesh surface 7 Comments Show Hide 4 older comments If you can fix these limits (e.g. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site Any help is appreciated. I think it just wants me to put points on the Max of each curve and I'm not sure how to do so. When I do this the 3D surface plot breaks down. These data points are in the "screened_data" table in the code below. By default, text supports a subset of TeX markup. Here we use hold on to prevent the current data from being deleted, then plot the new data with plotyy that also adds a dummy plot to the left axis (a single point 0,0). 'XLim', [0,10000], 'YLim', [-1, 1]) and set the undocumented properties 'YLimInclude' and 'XLimInclude' of the LINE handle to 'off', Matlab does not search the new min and max. ... Before declaring the original plot, add a hold on to ensure it will retain both plots, then plot the lines, with this structure: hold on; plot(the main function) plot([x x],[0 y_max]) % Vertical Line. I have a set of data points I am plotting using gscatter(). We then delete this dummy plot. Another method to gain speed: The XData and YData are searched at each update for min and max values to update the X- and Y-limits. I'd like the legend to also show the number of points in each dataset (e.g., 'Type1, n=7'). Hi all I am trying learn how to do a map with the air stations located on Pima county. Show your whole code or a minimal working example and your expected output. In this case, add text to the point (π, sin (π)). All the points classified as "Type1" plot as blue circles, "Type2" plot as green circles, etc. Surely, there must be a way to co-plot points onto a 3D surface plot? Still unclear, as I have an existing plot in my code and I add new points to it. I want to keep my question as simple and to the point as possible. Even in the absence of the plot3 command, just adding the hold on;/hold off; causes the surface plot to break down into a 2D heatmap. The third argument specifies the text. I have the county already my question is how can I add the latitude and longitude of each station on my code? 1. MATLAB: How to add plot points in the map. Instead, rewrite your code to produce a single variable named x that has all of the 'x' values, and another variable called y for the 'y' values. My point is, MATLAB functions should ALWAYS be consistent in how they work. Add text next to a particular data point using the text function. Don't create variable names like this in the first place.
