python - Matplotlib imshow displays blank plot -


i figured should simple guess not.

from scipy import misc import matplotlib.pyplot plt  img = misc.imread("alyson.jpg") plt.imshow(img) plt.show()

it draws blank canvas. inspecting array values loaded correctly. don't know issue be. i've tried loading matplotlib.image.imread , pil.image.open same effect.

i'm running lubuntu 13.04. here versions of various libraries:

pillow==2.5.2 matplotlib==1.3.1 numpy==1.8.2 scipy==0.14.0

edit: solved! switched rendering backend using matplotlib.use("wx").

not cause of problem was, switched backend wxpython , images loaded misc.imread or matplotlib.image.imread worked fine.

import matplotlib matplotlib.use("wx") import matplotlib.pyplot plt ...etc

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
