matplotlib - python plot horizontal line for a range of values -


i new python , trying plot speed constant value distince current startpointinmeters next startpointinmeters, speed constant start end (next start).

for example, speed should 13 distance 0 27.82 , 15 27.82 40.12 , on.

any idea?

startpointinmeters speed 0.0     13.0 27.82   15.0 40.12   14.0 75.33   14.0 172.77  17.0 208.64  18.0 253.0   21.0 335.21  20.0 351.16  25.0 590.38  22.0 779.37  21.0 968.35  22.0 1220.66 20.0 1299.17 19.0 1318.32 14.0 1352.7  9.0

this can done step function of matplotlib:

import matplotlib.pyplot plt  x = [0., 27.82, 40.12, 75.33, 172.77, 208.64, 253., 335.21, 351.16,      590.38, 779.37, 968.35, 1220.66, 1299.17, 1318.32, 1352.7] v = [13., 15., 14., 14., 17., 18., 21., 20., 25., 22., 21., 22., 20.,       19., 14., 9.]   plt.step(x, v, where='post') plt.xlabel('position [m]') plt.ylabel('speed [m/s]') plt.show()

result:

enter image description here

see this example difference between different values 'where' argument. description seems want 'post' option.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
