I want to have a sub array (between min and max) of a numpy 2D ndarray
xy_dat = get_xydata()
x_displayed = xy_dat[((xy_dat > min) & (xy_dat < max))]
min and max are float in order to be compare with the first value of the array xy_dat
xy_dat is a 2D numpy array :
[[ 735964. 1020. ]
[ 735964.04166667 1020. ]
[ 735964.08333333 1020. ]
...,
[ 736613.39722222 1095. ]
[ 736613.40416667 1100. ]
[ 736613.41111111 1105. ]]
x_displayed is correctly filtered but I have lost the second value (it is now a 1D array) :
[ 735964.04166667 735964.08333333 735964.125
...,
736613.39027778 736613.39722222 736613.40416667]
How make the filter on the first value and keep the other ?
