![]() xt get (gca, 'XTick') set (gca, 'XTickLabel', 2. ![]() You could either just change your label xlabel ('Log (base 2) of quantity X') or you can redo the ticks manually. If anyone has an idea of what I might be missing here, please share. You can plot directly using the plot command plot (log2 (x), y) but then your x ticks will be the logarithm rather than the actual value. It didn't yield the same size markers on the plot. I tried using log10(cSize) instead of cSize on lines 221-222, but this only slimmed the difference between the largest and smallest marker sizes. So, the marker size is not the same on the entire plot. Log Plot Using the loglog () Function in MATLAB If you want to plot the variables on a base 10 logarithmic scale on the x-axis and y-axis, you can use the loglog () function. Logarithmic scale allows a large range of data points to be displayed without the very small and/or large values to be compressed at the two ends of the graph. In the scatter_patches plot, the markers at the lower side of axes are bigger while they are smaller towards the higher-value side of axes. On a log plot, the lower-value regions of the axes are zoomed-in. We must remember, however, the function log(x) in MATLAB is the natural. However, after I fixed 1., the size of the markers was not uniform in my plot. Then logB(x) loge(x) loge(B) which is a constant multiple relative to loge. We can make the above, or any plot, more presentable with the following. This produces correct log scale and grid points.Ģ. A convenient way to plot data from a table is to pass the table to the loglog function and specify the variables to plot. x 1:100 y x.2 semilogy (x,y) grid on Plot Multiple Lines Create a vector of x -coordinates and two vectors of y -coordinates. ![]() Create a log-linear plot of x and y, and call the grid function to show the grid lines. This can be achieved by adding following after line 61: Plot One Line Create a vector of x -coordinates and a vector of y -coordinates. In order to obtain a log-log scatter plot with this program, I need to fix two things:ġ. Matlab also has support for semi-log plots in the commands semiology and. However, I am having issues adapting this code for a log-log scatter plot. There are two types of log plots in MATLAB: Log-log plot Semi log plot Log-Log Plot When we use a logarithmic plot with both axes in log scale, i.e. The easiest way to do this is simply use the following command instead of plot semilogy (x,y) This will plot x axis on a linear scale and y axis on a log scale. Let us assume that we would like to plot a function that represents the ranking. Then display the first three rows of the table. Furthermore, it is easier to directly use pyplot.yscale () than to use ax.setyscale ('log'), as there is no need to get the ax object (which is not always immediately available). I am using this wonderful tool 'scatter_patches' from Central File Exchange and it works very well: A convenient way to plot data from a table is to pass the table to the semilogx function and specify the variables to plot.
