javascript - flotr / protochart bar chart based on timestamps -

-

i want create bar chart flotr / protochart (tried both) can't work properly. when doing following, bars small grid line.

flotr.draw(             $('workflow-chart'),             [                 { label: 'd1', data: [[1291622400000, 3], [1291708800000, 8], [1291795200000, 7], [1291881600000, 0], [1291968000000, 5]] }             ],              {                 bars: {show: true, fill: true},                   xaxis: {                      tickformatter: function(t)                          {                              date = new date();                             date.settime(t);                              day = date.getdate() > 9 ? date.getdate() : "0" + date.getdate();                             month = date.getmonth()+1 > 9 ? date.getmonth()+1 : "0" + (date.getmonth()+1);                              return day + "." + month;                         }                 }             }         );

this question similiar flotr x-axis date/time hadn't helped.

you need set "mode" of xaxis here.

            xaxis: {                 mode: "time",                 tickformatter: function(t)                      {                          date = new date();                         date.settime(t);                          day = date.getdate() > 9 ? date.getdate() : "0" + date.getdate();                         month = date.getmonth()+1 > 9 ? date.getmonth()+1 : "0" + (date.getmonth()+1);                          return day + "." + month;                     }             }

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
