plot - Initialize y-axis to be centered at 0 -

-

i'm generating line plots show percent error results. nice if y-axis centered @ 0 when plots first load. know can manually set bounds y-axis, tedious have set them manually each figure.

is there way set figures center @ 0 along y-axis?

here's code may provide additional details - 

from bokeh.plotting import figure, output_file, show bokeh.io import gridplot, hplot  # prepare data x = [1, 2, 3, 4, 5] y1 = [-10, -9, 23, 4, -6] y2 = [-15, -4, 26, 32, -45] y3 = [-42, -20, -13, -34, -59] y4 = [-23, -34, -32, -43, -53]  # output static html file output_file("lines.html", title="line plot example")  # create new plot title , axis labels p = figure(title="simple line example", x_axis_label='x', y_axis_label='y') p.line(x, y1, line_width=2) p.line(x, y2, line_width=2)  p2 = figure(title="simple line example", x_axis_label='x', y_axis_label='y') p2.line(x, y3, line_width=2) p2.line(x, y4, line_width=2)  p = hplot(p, p2) show(p)

this generates 2 plots. 1 on right shows problem i'm running into. since of values negative, y-axis bounds narrowed approximately -10 -60. chart bound @ -60 60, it's aligned @ 0.

update: ended defining function return absolute max of y values. then, doing following set limits:

axislimit = getaxisrange(list1, list2) #get absolute max 2 lists p.y_range = range1d(start=-1*axislimit, end=axislimit)

there's no bokeh method center plot around axis describe. did did in update seems solution. you're welcome open issue on bokeh project tracker @ https://github.com/bokeh/bokeh/issues

python - No exponential form of the z-axis in matplotlib-3D-plots -

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
