axis-labels

问题 In matplotlib , when I use a log scale on one axis, it might happen that that axis will have no major ticks , only minor ones. So this means no labels are shown for the whole axis. How can I specify that I need labels also for minor ticks? I tried: plt.setp(ax.get_xticklabels(minor=True), visible=True) ... but it didn't do the trick. 回答1: I've tried many ways to get minor ticks working properly in log plots. If you are fine with showing the log of the value of the tick you can use matplotlib

问题 Is there an easy way to align text labels between ticks? Here is my time axis with labels above the ticks: I would like to place these labels like here: 回答1: I ended up with one of the Lars Kotthoff's advices. Every time when I call(axis) I also adjust text labels. Here is simplified code: function renderAxis() { axisContainer .transition().duration(300) .call(axis) // draw the standart d3 axis .call(adjustTextLabels); // adjusts text labels on the axis } function adjustTextLabels(selection)

问题 Here is my problem: polyfit does not take datetime values, so that I converted datetime with mktime producing the polynomial fit works z4 = polyfit(d, y, 3) p4 = poly1d(z4) For the plot however, I would like the datetime description on the axis and didn't # figure out how to do that. Can you help me? fig = plt.figure(1) cx= fig.add_subplot(111) xx = linspace(0, d[3], 100) pylab.plot(d, y, '+', xx, p4(xx),'-g') cx.plot(d, y,'+', color= 'b', label='blub') plt.errorbar(d, y, yerr, marker='.',

问题 I would like create a Matlab figure with a double X axis (m/s and km/h) with the same plot. I have found plotyy and - in Matlab reposity - plotyyy, but I am looking for: A double X axis. Together below the plot. My code is very simple: stem(M(:, 1) .* 3.6, M(:, 3)); grid on xlabel('Speed (km/h)'); ylabel('Samples'); M(:, 1) is the speed (in m/s), and M(:, 3) is the data. I would like only a second line, in the bottom, with the speeds in m/s. 回答1: You can do something like the following. In

问题 I combined 2 charts and I am trying to add the second y-axis, but every time I add the yaxis = "y2" to my code, I lose have the my bar graphs. > MediaDate Spend Search_Visits Other_Visits MediaDate2 > 2016-04-01 $39654.36 19970 2899 Apr 2016 > 2016-05-01 $34446.28 14460 2658 May 2016 > 2016-06-01 $27402.36 12419 2608 Jun 2016 my original code is: p <- plot_ly(x= w$MediaDate2,y=w$Search_Visits,name = "Paid Search", type = "bar") p2 <- add_trace(p, x=w$MediaDate2, y=w$Other_Visits,name = "Other

问题 I have the following code that makes four subplots in one figure: f = figure( figsize=(7,7) ) f.add_axes([0.2,0.175,0.75,0.75]) f.subplots_adjust(left=0.15) f.clf() ax = f.add_subplot(111) ax1 = f.add_subplot(221) ax2 = f.add_subplot(222) ax3 = f.add_subplot(223) ax4 = f.add_subplot(224) ax.xaxis.set_major_formatter( NullFormatter() ) ax.yaxis.set_major_formatter( NullFormatter() ) ax2.xaxis.set_major_formatter( NullFormatter() ) ax2.yaxis.set_major_formatter( NullFormatter() ) ax1.xaxis.set

问题 I'm plotting a log plot using matplotlib. My values go from 1 to 35. fig=plt.figure(figsize=(7,7)) fig.subplots_adjust(top=0.75, right=0.9) ax=fig.add_subplot(111) ax.plot(x, y, marker='o', color='black', ls='') ax.set_xscale('log') ax.set_yscale('log') I would like to set the x- and y-axis starting from values lower than 1, but if I use ax.axis([-10,45,-10,45]) it doesn't work. I know that it is because I'm using a log scale, but is there a way to solve the problem obtaining the axis I want?

问题 in gnuplot, when you try to fill an area under a curve, the tics of both axes are hinded behind the solid area. Is there any way to give them to the front? I am using postcript terminal, where no transparent features are allowed (i guess) Thanks 回答1: There sure is! Before plotting, run this interactively or in a script: set tics front Try help tics interactively for more info. 回答2: After trying many options I realized that the following works properly: set tics front It seems important to

问题 My data : dat <- data.frame(x = c(1,2,3,4,5,6), y = c(2,3,4,6,2,3)) Breaks and labels of my plot : breaks <- c(3,5) labels <- c(paste(3,"(0.3)"), paste(5,"(0.5)")) And my plot : library(ggplot2) ggplot() + geom_point(data = dat, aes(x = x, y = y)) + scale_y_continuous(breaks = breaks, labels = labels) I wish to colour the same labels differently. For instance, I wish to colour the "3" with a different colour than the one of "(0.3)". 回答1: Here's a way to stick 2 plots together with patchwork ,
