I use cassandra as my database. My data amount is 22GB after 6 hours and I now have around 3,4 Million rows, which should be read in under 5 minutes. But already it can't complete the task in this amount of time. My future plan is to read 100 Million rows in under 5 minutes . I am not sure what I can increase or do better to achieve this result now as well as to achieve my future goal. Is that even possible or would it be

This can be done with title = ax.set_title(...) bb = title.get_bbox_patch() In principle, one can then manipulate the

So in a figure where three vertical subplots have been added with add_subplot , how can I select let's say the middle one? Right now I do this list comprehension: [r[0] for r in sorted([[ax, ax.get_geometry()[2]] for ax in self.figure.get_axes()], key=itemgetter(1))] where I can simply select the index I want, with the corresponding axes . Is there a more straightforward way of doing this? Yann From the matplotlib documentation : If the figure already has a subplot with key (args, kwargs) then it will simply make that subplot current and return it. Here's an example: import matplotlib.pyplot

I am trying to create a 3D bar histogram in Python using bar3d() in Matplotlib. I have got to the point where I can display my histogram on the screen after passing it some data, but I am stuck on the following: Displaying axes labels correctly (currently misses out final (or initial?) tick labels) Either making the ticks on each axis (e.g. that for 'Mon') either point to it's corresponding blue bar, or position the tick label for between the major tick marks. Making the bars semi-transparent. image of plot uploaded here I have tried passing several different arguments to the 'ax' instance,

I searched here, and I know I can plot something like e.plot() but the time index (x axis) will be even interval, for example per 5 minutes. if I have to 100 data in first 5 minutes and 6 data for the second 5 minutes, how do I plot with number of data evenly. and locate the right timestamp on x axis. here's even count, but I don't know how to add time index. plot(e['Bid'].values) example of data format as requested Time,Bid 2014

Please start off by reading the answer by @user707650 Using MatPlotLib, I wanted a generalizable script that creates the following from my data. A window containing a subplots arranged so that there are b subplots per column. I want to be able to change the values of a and b . If I have data for 2a subplots, I want 2 windows, each with the previously described " a subplots arranged according to b subplots per column". The x and y data I am plotting

Is this possible? 回答1: There are a number of good suggestions on this closely related question , although they deal with a more complicated situation than yours. If you want a super-simple DIY solution, you can try this: plot ( rand ( 1 , 10 )); % Plot some random data ylabel ( gca , 'scale 1' ); % Add a label to the left y axis set ( gca , 'Box' , 'off' ); % Turn off the box surrounding the whole axes

What i am trying to achieve to no avail, is to allow the use of GridSpec with subplots , something like this, Where i can replace the actual Array and list indexes with some loop controlled index : gs = gridspec.GridSpec(4, 1, height_ratios=[2, 2, 1, 1]) tPlot, axes = plt.subplots(4, sharex=True, sharey=False) tPlot.suptitle(node, fontsize=20) axes[0].plot(targetDay[0], gs[0]) axes[1].plot(targetDay[1], gs[1]) axes[2].scatter(targetDay[2], gs

I set the position relative to the figure by ax.transAxes, but I have to define the relative coordinate value manually depending on height scales of each figures. What would be a good way to know axes height scale and the correct text position within the script? ax = plt.subplot(2,1,1) ax.plot([1,2,3],[1,2,3]) ax.set_aspect('equal') ax.text(1,-0.15, 'text', transform=ax.transAxes, ha='right', fontsize=16) print ax.get_position().height ax = plt.subplot(2,1,2) ax.plot
