from post got how create graph, struggling add scale bar. printing item colors gives [ 0.53800422 0.67490159 0.99172189 1.] i'm guessing scaled color? my_array = range(20) my_array2 = my_array z = np.array(my_array) x = np.asarray(my_array) scaled_x = (x - x.min()) / x.ptp() scaled_z = (z - z.min()) / z.ptp() colors = plt.cm.coolwarm(scaled_z) graph = plt.scatter(my_array, my_array2, c = colors, cmap = colors ) cb = plt.colorbar(graph) cb.set_label('mean value') plt.show() i think you've gotten mixed on cmap argument supposed be. it's either colormap object (e.g. plt.cm.coolwarm ) or name of colormap (e.g. "coolwarm" ). you're trying pass in explicit colors. (the [ 0.53800422 0.67490159 0.99172189 1.] red, green, blue, , alpha values colormap yield 1 of specific data points.) instead of calculating explicit colors, pass in colormap object directly. for example, given example code above, re-write as: import numpy np

i planning learn develop ios apps. i'll learning objective-c , develop actual apps ios. now, launch of swift 2.0, objective-c apps still run on ios9 ? also, possible test run objective-c app on phone mentioned here ? https://developer.apple.com/xcode/ or facility available apps written in swift? does swift allow me objective-c does? any further advide or guidance should know before enrolling course appreciated me judge things better. swift still second language. cocoa frameworks written in c or obj-c (maybe new ones in ios 9 written in swift). the language in application written doesn't matter, code compiled same machine code, yes, obj-c apps continue run , many developers won't bother swift. apps have been written not have rewritten swift (with exceptions). swift won't allow absolutely obj-c allow almost , code more robust, considering swift more modern language stronger typing obj-c. if beginner, won't find problematic use case.
