Hi matplotlib_users ! I'm David from Berlin, and believe I'm experiencing some problem with the SubplotHost module: I'm generating graphs from hudge databases of cpu and ethernet statistics, and I wanted to mix several graphs concerning ethernet statistics in the same figure, with time as x axis, and bytes-in, bytes-out, packets-in, packets-out and number of collisions as three different y axes, with three different scale. I took the inspiration from for the x axes and from http://matplotlib.sourceforge.net/examples/axes_grid/demo_parasite_axes2.html for the y axes The following code is a synthetic reproduction of the problem I'm experiencing (it is also attached): from matplotlib.dates import date2num from matplotlib import pyplot from matplotlib import pylab from mpl_toolkits.axes_grid.parasite_axes import SubplotHost from datetime import datetime dates = [ 733581.20833333337, 733581.20837962965, 733581.20842592593, 733581.20847222221, 733581.20851851848, 733581.20855324075, 733581.20858796302, 733581.2086342593, 733581.20866898145, 733581.20871527772] rxB = [054L, 130L, 144L, 54L, 36L, 9L, 35L, 43L, 85L, 43L] txB = [4L, 9L, 9L, 5L, 4L, 4L, 4L, 5L, 6L, 5L] rxP = [77, 228, 251, 112, 77, 42, 75, 97, 147, 91] txP = [61, 177, 188, 90, 61, 40, 64, 76, 113, 77] col = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0] ethPlot = pyplot fig = ethPlot.figure() host = SubplotHost(fig, 111) host.set_ylabel("kB/s") host.set_xlabel("Time") par1 = host.twinx() par2 = host.twinx() par1.set_ylabel("Packets/s") par2.axis["right"].set_visible(False) offset = 60, 0 new_axisline = par2.get_grid_helper().new_fixed_axis par2.axis["right2"] = new_axisline(loc="right", axes=par2, offset=offset) par2.axis["right2"].label.set_visible(True) par2.axis["right2"].set_label("Collisions") par1.set_ylim(0, 6000) par2.set_ylim(0, 7000) host.axis([ dates[0], ( dates[0] + 0.041 ), -7000, 7000]) par1.axis([ dates[0], ( dates[0] + 0.041 ), -10000, 10000]) par2.axis([ dates[0], ( dates[0] + 0.041 ), -700, 700]) fig.add_axes(host) ethPlot.subplots_adjust(right=0.75) drawRxByt, = host.plot_date(dates, rxB, 'g', tz=None, xdate=True, ydate=False, label="kB/s in") drawTxByt, = host.plot_date(dates, txB, 'b', tz=None, xdate=True, ydate=False, label="kB/s out") drawRxPaq, = par1.plot_date(dates, rxP, 'm', tz=None, xdate=True, ydate=False, label="packets/s in") drawTxPaq, = par1.plot_date(dates, txP, 'y', tz=None, xdate=True, ydate=False, label="packets/s out") drawColls, = par2.plot_date(dates, col, 'r', tz=None, xdate=True, ydate=False, label="collisions") fig.autofmt_xdate() host.set_xlabel("Time") host.set_ylabel("kB/s") par1.set_ylabel("Packets/s") host.legend() host.axis["left"].label.set_color(drawRxByt.get_color()) host.axis["left"].label.set_color(drawTxByt.get_color()) par1.axis["right"].label.set_color(drawRxPaq.get_color()) par1.axis["right"].label.set_color(drawtxPaq.get_color()) par2.axis["right2"].label.set_color(drawColls.get_color()) ethPlot.draw() pylab.savefig( './test.png', dpi=(640/8)) Maybe I do something wrong somewhere here, but other scripts that do the same for a single graphwork like a charm. So it's not a question of dataType or something. To compare with a working code, here is the first version of the fuction that does the job on single graphs without any problem : def drawEthGraph(filename, hdates, rxP, txP, rxB, txB, col): ethPlot = pyplot fig = ethPlot.figure() ax = fig.add_subplot(111) ax.plot_date(hdates, rxP, 'g', None, True, False) ax.plot_date(hdates, txP, 'b', None, True, False) ax.plot_date(hdates, rxB, 'g', None, True, False) ax.plot_date(hdates, txB, 'b', None, True, False) ax.plot_date(hdates, col, 'r', None, True, False) ax.axis([ hdates[0], ( hdates[0] + 0.042 ), -7000, 7000]) ax.grid(True) fig.autofmt_xdate() pylab.savefig( filename, dpi=(640/8)) I don't think I understand the whole process of generation, but I thought at least at the beginnig I was having a good feeling with this API. Now I wonder how to go around this. Maybe you'll have an idea :-o Best regards DvD
I can reproduce the error with the svn version. It seems that the problem is not SubplotHost specific, i.e., you have same problem if you use mpl's original axes with twinx. I think it has something to do with the axes sharing in general. Preventing autoscale of xaxis suppress the error. host.set_autoscalex_on(False) par1.set_autoscalex_on(False) par2.set_autoscalex_on(False) But you have to manually adjust the x-limits later par1.set_xlim(dates[0], dates[-1]) However, autofmt_xdata does not work. And I guess this is a bug in the SubplotHost. I may take a more look later today.

Hi matplotlib users! Did someone solve the problem of use fig.autofmt_xdate() function with SubplotHost object? I googled for it and I found this question only here, without solution. Is there a bug? Anyone knows someway to solve this?

The workarounds suggested in this thread does not work? To me, the ordinal thing is not actually a bug, but you need some extra caution to avoid this error happening. The issue with the label roration is a different matter though.

Hello, I came across problem of label rotation with autofmt_xdate() in subplothost too. Is there a new version with the bug fixed or a workaround to doing the label rotation in subplothost?

One workaround is to turn off axisline mode. host = SubplotHost(fig, 111) host.toggle_axisline(False) Note that, with this change, things like host.axis["left"].label.set_color(drawRxByt.get_color()) won't work and you have to use the methods of original matplotlib Axes.
