"auto" option uses the same color as the only one variable. coordinates is to use the polarscatter or geoscatter functions. Anyway, here are three examples in case it helps: You may receive emails, depending on your. equivalent to plotResiduals(mdl). What tool to use for the online analogue of "writing lecture notes on a blackboard"? I will show you what I did. Add a legend, and notice that the legend labels match the variable names. % Erase all existing variables. Edited: Chad Greene on 18 Dec 2014. To use the same size for all the circles, specify The scatter(x1, x2) followed by lsline works ok for me How is this "not programming related" is beyond me @Amro I have the same problem to find the best fit line. To stop the update process, press the pause button in the progress indicator. For example, read Patients.xls into the The above single line will plot x marks at each point, and connect them with a line, all in blue. Other than quotes and umlaut, does " mean anything special? Suppose you have some data in y and you have corresponding domain values in x, (ie you have data approximating y = f(x) for arbitrary f) then you can fit a linear curve as follows: Note that if you want to fit an arbitrary polynomial to your data you can do so by changing the last parameter of polyfit to be the dimensionality of the curvefit. plot (x (1:8),y (1:8),'b-x') There is NO need for a loop. intermediate rows. Are there conventions to indicate a new item in a list? See my attached polyfit demo. For example, if you pass a table containing a variable named Sample_Number Choose a web site to get translated content where available and see local events and For example check following packages on FEX which do a similar thing, https://www.mathworks.com/matlabcentral/fileexchange/22470-lowess-locally-weighted-scatterplot-smoothing-for-linear-and-non-linear-data-enhanced, https://www.mathworks.com/matlabcentral/fileexchange/19195-kernel-smoothing-regression, If You have the curve-fitting toolbox, then you can also use smoothingspline option with fit(). Create a different color for each data Note that the x-data of the line goes from 0 to 3. % Volumetric volume flow rate vs delP fan, 'Volumetric Flow Rate vs. Delta Pressure Venturi'.
