Hi, I need to plot my simulation (which I do in a C++ application) for use in a Latex document (so I would prefer some vector output like EPS). My function is of 2 arguments, so I am after a 3D plot, ideally with colouring indicating the function value (similar to what Mathematica does). Could anyone recommend any library? ...
I like to create a "report generation" script in Matlab. Suppose we have a Matlab array, data and we want to export the following to a .tex file: "The information in the first element of data is X." This would be followed by a plot of X. I have already tried help latex in Matlab and aware of the various packages on Matlab file exchang...
any chart / graph / plotting c c++ library which is similar as bloomberg chart, with mouse interaction on plotted line, and multilayer plot? gnuplot is very powerful but it seems to me it can feed in data but no callback to mouse action and no manipulation on plotted line / chart, e.g. over mouse over particular line and I would dump th...
Hi, I'd like to plot mosaic bar or spinogram like here: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=117, but I'd like to have vertically streched 3-letter string legend inside of each bar. Any ideas how to implement this easily? ...
I want to plot a 3d graph in matlab By graph I mean in the sense of nodes and edges. I have an adjacency matrix as well as a coordinate matrix for every node. Eventually I would hope to colour these nodes and edges The gplot function is only 2d. The scatter3 function does not allow for edges. Any ideas? ...
Hi! Just imagine you plot several dots, circles, lines in a figure. Afterwards another m file should use this plot as an input to do e.g. thresholding. I'm aware of the print command but I don't want the plot to be stored as file. I would prefer to store it in a matrix (x_dim,y_dim,3). Any ideas? ...
I have a plot like this: http://i.imgur.com/i9xp5.png I need the data coordinates of points in order to plot wind barbs. Now, if I wanted a wind barb to be drawn at x=100, y=20, is there a way I can obtain the data coordinates of that ( or other ) points of my plot? ...
I'm looking for ways to programmatically convert my GPS logs to images and would like to do this in Ruby... if that's an acceptable tool. I have no GIS background whatsoever but as a programmer i think it's an interesting problem to look at. Here is what I have come up with so far. First you'll need some kind of graphing library. I went...
hello everyone, i need to plot velocity graph for my velocity vector data(x axis velocity x comp, y axis velocity y comp). there is a quiver plot in matlab which does so, is it possible to some how draw such graphs in Java. please some one can tell how to do it, it would be real help. ...
Hi! I need to plot, in 3D, a set of densities associated to a time series. More precisely, I would like to be able in R to build an image close to this example This image is taken from [1]. The transparency plays an important role as let us see the trajectory of the "measures" in the x-y plane. Any help will be greatly appreciated...
Hi, I'm very new to python. two days. trying to get a plot working with matplotlib. I'm getting this error: cannot perform reduce with flexible type the line with the error is: ax.scatter(x,y,z,marker='o') Variables: ax is defined as: ax = Axes3D(fig) fig is defined as: fig = plt.figure() x, y, z are lists Any python expert...
I have two data.frames, one containing raw data and the other containing modelling coefficients that I have derived from the raw data. More detail: The first data.frame "raw" contains "Time" (0s to 900s) and "OD" for many Variants and four runs. The second data.frame "coef" contains one row per Variant/run combination, with the individ...
Is there an easy way to remove a plotted line from a set of axes without clearing everything else on the axes? I'm trying to implement a GUI with a listbox containing several data sets. I can make the callback function plot the selected data, but I'm not sure how to 'unplot' it when I deselect a data set. Any ideas? ...
I am currently trying to use the package "ape" in R for drawing phylogenetic trees (like dendograms). What I would like to know is whether it is possible to add (directed) arcs between the leafs of the dendogram, in addition to the dendogram itself, and have some number above them. It is like having a directed (maybe complete) graph ove...
Hi guys, I am looking for a plotting library that can be used in web applications (point and line plots are must - antyhing else is a bonus). It might be either server-side (Python) or client-side. The more interactive graphs are the better. I have found some solutions of course, but none of them are good enough for volume of datasets...
I am trying to create a 2D map of some place. I get a 181x1 vector of laser sensor readings from a robot. All the values in this vector corresponds to a distance from that single angle like 1°,2°..180°. The problem here is I need to create a map by plotting these distances as dots with plot() or a similar function to it. ...
I have some 100k values. When I plot them as a line in R (using plot(type="l") the numbers next to the x-axis ticks are printed in scientific format (e.g. 0e+00,2e+04,...,1e+05). Instead, I would like them to be: A) 0,20kb,...,100kb B) the same but now the first coordinate should be 1 (i.e. starting to count from 1 instead of 0). BTW ...
Usually when I plot some R line plot and set ylim=c(0,some_value), there is small space between the x axis and y=0. I would like the y axis to show exactly at y=0 so points (x,0) will be plotted on the y axis (and not above). ...
I am trying to add arrows marking specific x coordinates below the x axis in an R plot. My x axis is at y=0 and when I try to use negative y-coordinates in arrows, so the arrows will be perpendicular to x axis, I get only the very edges of the arrow plotted (although is some space, e,g where the x-axis label and tickmarks are plotted). ...
I'm trying to specify custom Y axis tick marks, but IDL is not cooperating. http://i.imgur.com/BFqMO.png In the top left, 1.0000 should be the max value, but IDL puts a 57 there. 57 is the max array dimension of my data. I have an array of eta levels(strings) corresponding 1:1 with the array indices, and I want to use them as tick m...
