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) ...

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)...

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...

The problem is that you're only converting the edges of the array. By converting only the x and y coordinates of the edges, you're effectively converting the coordinates of a diagonal line across the 2D array. This line has a very small range of theta values, and you're applying that...

SOLUTION So, I solved this issue and the solution is really trivial. When you do, chart.series[0].addPoint([x,y], true, true), it shifts the most recent coordinate by one point while appending the newest coordinate to the end. It's like an array - more specifically, this is stack: chart.series[0].data.y where new points are...

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...

As pointed out by horchler, the mistake was in my color conversion (RGB to XYZ to xyY) which I had done external to MATLAB. On correcting the error, the following code produced the desired result. cieplot(); hold on x=[0.42 0.38 0.388 0.352 0.344 0.281] y=[0.48 0.45 0.5 0.45 0.452 0.352];...

You can change the position of an svg object (like a group) element with translate. For example: <g transform="translate(20,20)"></g> Check a live example here: http://jsbin.com/zajij/1/ In d3 you can add an attr to add this transform .attr("transform", "translate(20,20)"); Hope this helps!...

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. For example s <- scatterplot3d(x,y,z) with(s$xyz.convert(c(4,4),c(2,9),c(0,0)), lines(x, y, lwd=2)) with(s$xyz.convert(c(1,6),c(4,4),c(0,0)), lines(x, y, lwd=2)) Here we...

As told in the comment, scatter can take a 4th argument which will represent the color. The 3rd argument (the one you use with c for each of your scatter plot), only controls the size. For you, the way to call scatter should be: scatter(x,y, size, colour , 'filled') Read...

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',...

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...
