How to display values on a plot Showing 1-15 of 15 messages. qqplot(x) displays a quantile-quantile plot of the quantiles of the sample data x versus the theoretical quantile values from a normal distribution.If the distribution of x is normal, then the data plot appears linear. num2str is fine (as would be sprintf) to use to format a value for display with additional text using the format string. To display it, you use text You can also use annotation object for an arrow pointing to the value and so on. display max ,min and a value of array in plot . y=(xˆ2+12x+24) for the value of x between 0 to 12. The titlecommand allows you to put a title on the graph. qqplot plots each data point in x using plus sign ('+') markers and draws two reference lines that represent the theoretical distribution. The function of y(x)= Sin(x) for 0 Next > How to label a series of points on a plot in MATLAB. One can specify colors using a vector that gives the RGB triple where in MATLAB, each of the three values are numbers from 0 to 1. Plotting Data Introduction. I will use and refer to several DIPUM3E functions. Click the Add Data button to display the Add Data to Axes dialog. 0. I am plotting x vs y and I am taking out the maximum value of x with max(x). And if you make a stacked plot from a timetable, the x-values are the row times. hello there, i have 15 (x) points named x1 to x15; and corresponding to this i have 15 (y) points named from y1 to y15.
