 [Matplotlib-users] 1D heat map From: aint - 2011-08-31 18:22:24 ```Hi, I have a code for making graphical representations of sentences, Sentence is represented as a bar, and under in you can represent the words. It works fine and I have an example at the end. Now I wanted to add some more features to it, but I am stuck. you can see the previous post from this link Now, if we assign a number to each letter in a sentence and get a list of these numbers, [2,4,7,-7,8,6,4,4,-7,9,5,3,-7,9,5,-3,7,8,9,5,3,6,8,9,-5,3] can I create a 1D heat map with this list as and additional bar? First problem will be to get the range of numbers and normalize it, or we should be able to assign a range for the heat map. It would be great if you can help. here is the example code. [CODE] text ='''World number two Nadal breezed through the first set, taking it with breaks of serve in the fourth and sixth games. Monfils put up more resistance in an erratic second set but his wayward display was summed up by a double fault which sealed Nadal's victory. The Spaniard will face a semi-final against compatriot Nicolas Almagro, who beat Austrian Juergen Melzer 6-3 6-1. In the women's competition, fourth seed Venus Williams booked her place in the semi-finals with a 6-3 6-3 win over Australia's Samantha Stosur.''' import pylab import matplotlib # Put text into list of sentences sentences = [] sentences = text.split('\n') # Get the lenght of longest sentence-Lmax and number of sentences Lmax=0 it = 0 for i in sentences: it = it + 1 LenSen= len(i) if LenSen > Lmax: Lmax = LenSen totalnumber = it #Set the image properties pylab.rcParams['figure.figsize'] = [Lmax/20, totalnumber] pylab.rcParams['figure.subplot.left'] = 0.2 # Left margin pylab.rcParams['figure.subplot.right'] = 1.0-0.04 # Right margin pylab.rcParams['font.size'] = 7 # Axes range from 0 to 1 for x-axis (simplifying calls to .axhspan()) and # 20 down to 0 for Y-values because that's convenient for this example ax = [0, 1, totalnumber+1, 0] # [xlo, xhi, ylo, yhi] # printer is a drawing module def printer(searchterm, Input,start,end,xstart,color): lens = len(searchterm) while True: inDex = Input.find(searchterm, start,end) if inDex == -1: break inDex = float(inDex) inDS=inDex/Lmax inDE=(inDex+lens)/Lmax matplotlib.pyplot.axhspan(it+xstart,it+0.2+xstart, xmin=inDS, xmax=inDE, ec='k', fc=color) # if search string not found, find() returns -1 # search is complete, break out of the while loop # move to next possible start position inDex= int(inDex) start = inDex + 1 it=0 for i in sentences: it = it+1 LenSen= len(i) LenF = float(LenSen) matplotlib.pyplot.axhspan(it+0.2,it+0.4, xmin=0, xmax=LenF/Lmax, ec='k', fc='r') #creates sentence bar pylab.text(-0.2, it+0.4, 'sentence'+str(it)+' with spaces') # create the sentence bar printer(' ', i, 1, LenSen,0.2,'b') #blue represents the spaces on sentence bar printer('the', i, 1, LenSen,0,'y') #above sentence bar, yellow represents 'the' pylab.text(-0.2, it+0.2, 'the') pylab.axis(ax) matplotlib.pyplot.title("Analysis") matplotlib.pyplot.xticks((),()) # No labels for X-axis matplotlib.pyplot.yticks((),()) # No labels for Y-axis pylab.show() [CODE] -- View this message in context: http://old.nabble.com/1D-heat-map-tp32374379p32374379.html Sent from the matplotlib - users mailing list archive at Nabble.com. ```
