Why does plot behave differently for different data, and how do you control it? My specific example today is getting different output with scaled and non-scaled data. For example fit <- kmeans(mydata, 4) plot(mydata, col = fit$cluster) returns a nice 4x4 scatter matrix plot (mydata is 486x4) but mydata <-...

I have been trying for several hours to globally turn off scientific notation and the offset in matplotlib. my attempt at a solution import matplotlib as mpl import matplotlib.pyplot as plt The documentation says: set the rcParam axes.formatter.useoffset=False to turn it off globally, or set a different formatter. mpl.rcParams.formatter.useoffset =...

excuse my noobness, but this is my first post. i generated this gui in matlab, and i want to plot an image on one of the axis from an update function. i know in Matlab you can just do something like image(img) hold on plot(x1,z1) hold off but how can...

Recently I am trying to implement the ISO classification for the roadway assessment. Please refer to the paper The use of vehicle acceleration measurements to estimate road roughness. But I bumped into some questions about plotting the ISO classification graph. The code is shown as follows: %% generate ISO Clasification...

I have a gnuplot code which includes a function fitting routine. This routine is slow when a large number of data points must be fitted. The number of data points in my input file is variable depending on the parameters of some simulations I am running. I wish to fit...

I would like to plot a function several times, each time changing a parameter (a constant) in the function. How can i do this? fun1 <- function(x, b) abs(x^2 - b^2) plot(fun1(b=0.1),-1, 1) plot(fun1(b=0.2),-1, 1, add=TRUE) ...

How can we write a legend that overlay several frames? Using the xpd parameter, the legend can exit its frame but still cannot enter the next frame. par(mfrow=c(1,2)) plot(rnorm(120), rnorm(120)) legend(x = -0.1, y=0.1, legend = "Legend that covers both plots", text.col="red", cex=2, box.col="red", xpd=TRUE) plot(rnorm(120), rnorm(120)) One dummy solution...

I have a question about add shading in my figure. I need to shading all subplot like the picture below, how to do it in Python?

I have multiple 2D line plots in Matlab (they represent some wave moving through space). Each plot represents the wave at some time t. I want to animate through these plots (i.e. show the first plot for a fraction of a second, then show the next one, and the next,...

I am try to plot 16 bars, 8 of these belong to one group. I want to give this group the red color, the other 8 belong to another group which is given the blue color. I would like to arrange the bar in pairs, each pair containing one from...
