you to create simple x-y plots with linear axes. For example, x = -10:0.1:10; plot (x, sin (x)); displays a sine wave shown in Figure 15.1.

Many different combinations of arguments are possible. The simplest form is plot (y) where the argument is taken as the set of y coordinates and the x coordinates are taken to be the range 1:numel (y). error bars plot python If more than one argument is given, they are interpreted as plot (y, property, value, …) or plot (x, y, property, value, …) or plot (x, y, fmt, …) and so on. Any number of argument sets may appear. The x and y values are interpreted as follows: If a single data argument is supplied, it is taken as the set of y coordinates and the x coordinates are taken to be the indices of

the elements, starting with 1. If x and y are scalars, a single point is plotted. squeeze() is applied to arguments with more than two dimensions, but no more than two singleton dimensions. If both arguments are vectors, the elements of y are plotted versus the elements of x. If x is a vector and y is a matrix, then the columns (or rows) of y are plotted versus x. (using whichever combination matches, with columns tried first.) If the x is a matrix and y is a vector, y is plotted versus the columns (or rows) of x. (using whichever combination matches, with columns tried first.) If both arguments are matrices, the columns of y are plotted versus the columns of x. In this case, both matrices must have the same number of rows and columns and no attempt is made to transpose the arguments to make the number of rows match. Multiple property-value pairs may be specified, but they must appear in pairs. These arguments are applied to the line objects drawn by plot. Useful properties to modify are "linestyle", "linewidth", "color", "marker", "markersize", "markeredgecolor", "markerfacecolor". See Line Properties. The fmt format argument can also be used to control the plot style. It is a string composed of four optional parts: "

Matlab Error Bars Plot
error bars in GNU Octave, a free open-source numerical programming and analysis literary terms octave tool that is mostly compatible with MATLAB. Octave can display standard two dimensional plots using the plot command. Unfortunately, octave hist plot does not support error bars. Fortunately, Octave has an errorbar command which can display error bars. This post shows how to combine the raw data plotted with the Octave https://www.gnu.org/software/octave/doc/v4.0.3/Two_002dDimensional-Plots.html plot command with a polynomial model fit to the data with the error bars on the polynomial fit results from the Octave polyfit command.

You just have to change the plot command on line 184 with a bar(mittel(:,1),mittel(:,2),FARBEm) and you get a bar chart with error bounds. error bars plot Just get rid of the extra code to calculate means, etc. Regards Jürgenplmeanx.m Henry F.

X coordinates are taken to be the indices of the elements, starting with 1. If more than two arguments are given, they are interpreted as errorbar (X, Y, ..., FMT, ...) where after X and Y there can be up to four error parameters such as EY, EX, LY, UY etc., depending on the plot type. Any number of argument sets may appear, as long as they are separated with a format string FMT. If Y is a matrix, X and error parameters must also be matrices having same dimensions. The columns of Y are plotted versus the corresponding columns of X and errorbars are drawn from the corresponding co

I can not find a way how to plot with error bars but without the lines connecting the points. For example: x=linspace(0,1,10) y=sin(x) yerr=linspace(0,0.2,10) # plot with points; no connecting lines, good plot(x,y,'@') # plot with errorbars; connecting lines are plotted errorbar(x,y,yerr,'~') Could anyone please tell how can I get the plot I want?
