python,matplotlib,scatter-plot,colorbar,color-mapping

I ended up going with this. I'm not sure if it is the best way - if you have alternate suggestions perhaps I can learn from them for future use! cmap = matplotlib.colors.ListedColormap(['green', 'blue', 'red']) bounds=[0,125,200,400] cax = inset_axes(ax3, width="8%", height='70%', loc=4) cbar = matplotlib.colorbar.ColorbarBase(cax, cmap=cmap, boundaries=bounds) cax.yaxis.set_ticks_position('left') cbar.ax.set_yticklabels(['0', '125',...

I would do something like the following: import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D # choose your colormap cmap = plt.cm.jet # get a Nx4 array of RGBA corresponding to zs # cmap expects values between 0 and 1 z_list = np.array(z_list) # if z_list...

ok, in case anyone else runs into this and needs a suggestion...I've found that Android Plot (http://androidplot.com/) meets my needs. It has good native support for XY graphs and seems like a good package all around. I wish the javaDocs were a little more developed - a lot of functions...

python,pandas,matplotlib,legend,scatter-plot

You can change the size of the symbol in the legend using the markerscale keyword. For example, ax.legend( scatterpoints=1, loc='best', ncol=1, markerscale=0.5, fontsize=12) will reduce the symbol size by a factor 2....

You might want to convert your x-values into factors. Right now, R assumes that your x-values are numbers and hence puts the appropriate space between them (the difference between 5,884 and 13,957 is larger than the difference between 21,013 and 28,708). However, you probably think of the numbers as names...

python,matplotlib,scatter-plot,bubble-chart

Your plot command was wrong; you need to specify x and y for each point you want to plot , so 4 values for both x and y. See the docs for more info (specifically about the shape of x and y) import matplotlib.pyplot as plt x = [1, 2,1,2]...

look at the sunflowerplot function (and the xyTable function that it uses to count overlapping points). You could also use the my.symbols function from the TeachingDemos package with the results of xyTable to use other shapes (polygrams or example)....

Currently that is not possible as you describe it, since the position on the x-axis can only be an integer (x-index). However, you can of course scale that up and then represent float....

r,classification,weka,scatter-plot

You can use Multidimensional Scaling (MDS) to first, reduce the dimension of your data and then plot it. This method tries to preserve the distances between points when projecting into a lower dimension. Here is an example in R for the iris dataset data <- iris colors <- as.integer(as.factor(data$Species)) d...

In the end, I came up with the following: Use scatterhist to create the scatter plot with marginal histograms. hold on Use convhull to get the convex hull for each group of points. Use fill to draw the convex hull. ...

r,scatter-plot,kernel-density,density-plot

Seems like you want a filled contour rather than jus a contour. Perhaps library(RColorBrewer) library(MASS) greyscale <-brewer.pal(5, "Greys") x <- rnorm(20000, mean=5, sd=4.5); x <- x[x>0] y <- x + rnorm(length(x), mean=.2, sd=.4) z <- kde2d(x, y, n=100) filled.contour(z, nlevels=4, col=greyscale, plot.axes = { axis(1); axis(2) #points(x, y, pch=".", col="hotpink")...

I think something like this would be ok for start? ggplot(data = df, aes(x=var1, y=var2, shape = var3, color = var3)) + geom_point(size=4)+ geom_text(data=df[3:4,],aes(x=var1,y=var2,label=var4), color='black') To remove the circles for the 3rd and 4th row change the first row to this: ggplot(data = df[-c(3:4),], aes(x=var1, y=var2, shape = var3, color...

Are you thinking of the confidence interval for binomial proportion? see http://en.wikipedia.org/wiki/Binomial_proportion_confidence_interval E.g. binom.test(208,14824) the 95% CI is [1.22, 1.61] for your sample estimate 1.40 (percentage)

If you want both scatter points and circles of a given size (relative to the x-axis coordinates or actual size in inches/cm) I suggest you use the symbols() function x <- 10*runif(4) y <- 10*runif(4) symbols(x, y, circles=rep(3, length(x)), inches=FALSE, xlim=c(0,10), ylim=c(0,10)) points(x, y, pch=19) ...

Yes it can! You just need to provide the rotation property of text annotations with a value of 90 and it works fine. Example: clear clc x = [29.745, 61.77, 42.57, 70.049, 108.51, 93.1, 135.47, 52.79, 77.91, 116.7, 100.71, 146.37, 125.53] y = [6, 6, 12, 24, 24, 12, 24,...

Without your data it's hard to verify but I suspect the only problem is that you are regressing had ~ fatigue in your model but you're plotting x = hads, y = fatigue. The formula in lm should be of the form y ~ model so I think you just...

d3.js,scatter-plot,semantic-zoom

You just need to rebind the new scales to the behavior. First put the zoom behaviour function in a variable so you can access it later: Your original code... var svg = d3.select("#scatter") .append("svg") .attr("width", outerWidth) .attr("height", outerHeight) .append("g") .attr("transform", "translate(" + margin.left + "," + margin.top + ")") .call(d3.behavior.zoom().x(x).y(y).scaleExtent([0,...

python,matplotlib,plot,scatter-plot,aspect

You can do it like this: import matplotlib.pyplot as plt fig, ax = plt.subplots() x = [0, 0.2, 0.4, 0.6, 0.8] y = [0, 0.5, 1, 1.5, 2.0] colors = ['k']*len(x) ax.scatter(x, y, c=colors, alpha=0.5) ax.set_xlim((0,2)) ax.set_ylim((0,2)) x0,x1 = ax.get_xlim() y0,y1 = ax.get_ylim() ax.set_aspect(abs(x1-x0)/abs(y1-y0)) ax.grid(b=True, which='major', color='k', linestyle='--') fig.savefig('test.png', dpi=600)...

python,matplotlib,widget,scatter-plot

The graph updates itself when you set new limits. You just don't see this because you update wrong subplot. Just select right subplot to update: def update(val): plt.subplot(111) plt.ylim([smin.val,smax.val]) (this work for me) or maybe even: def update(val): plt.ylim([smin.val,smax.val]) plt.subplot(111) smin.on_changed(update) smax.on_changed(update) if you don`t do anything with it elsewhere...

python,pandas,colors,scatter-plot

You're getting a Series back from df.ix[0], which can't be drawn as a scatter plot. (I guess it could be a valid type in theory, but, as you say, it would only show 1 point.) If you change your code slightly to make sample a DataFrame instead, it works. (I've...

You can set the y tooltip content to null to achieve this: var chart = nv.models.scatterChart() .showDistY(false) .tooltipYContent(null); ...

python,scatter-plot,marker,colorbar

scatter can only do one kind of marker at a time, so you have to plot the different types separately. Fortunately pandas makes this easy: import matplotlib.pyplot as plt import pandas as pd x = {'speed': [10, 15, 20, 18, 19], 'meters' : [122, 150, 190, 230, 300], 'type': ['phone',...

The data in the mzRange is not numeric. If it is used as the data source for the X axis, it will result in the data points being numbered ascending on the X axis. The only way to plot over a data point is to use the exact X and...

Well, it doesn't look like there is a super straight forward way to do this in the scatter plot command itself, but you can find positions after you make the plot and draw on top.

Can you draw half a million points with D3? Sure, but not with SVG. You'll have to use canvas (here's a simple example with 10,000 points that includes brush-based selection: http://bl.ocks.org/emeeks/306e64e0d687a4374bcd) and that means that you no longer have individual elements to assign click handlers to.
