各カテゴリに色を付けるにはどうすればよいですか？

Question

地図上の場所に各カテゴリの名前で円を描くコードがあります。今、円とテキストは1つの色です。私たちはどのようにカテゴリー別に色を変えますか？例：カテゴリガーデン：青、カテゴリストーン：グレー。

これまでコード：

size(1500,800) 
background(1) 
nofill() 
stroke('#f91') 
pen(.2) 
fill('#f91', 0.05) 
rotate(90) 

font("Avenir", "bold", 10) 
align('left') 


def mapValue(value, fromMin, fromMax, toMin, toMax): 
    # Figure out how 'wide' each range is 
    fromSpan = fromMax - fromMin 
    toSpan = toMax - toMin 

    # Convert the from range into a 0-1 range (float) 
    valueScaled = float(value - fromMin)/float(fromSpan) 

    # Convert the 0-1 range into a value in the to range. 
    return toMin + (valueScaled * toSpan) 

def xOfDot(lon): 
    return mapValue(lon, -100, 100, 0, WIDTH) 

def yOfDot(lat): 
    return mapValue(lat, -90, 90, HEIGHT, 0) 


with open('theft-alerts.json', 'r') as inputFile: 
    data = json.load(inputFile) 

print len(data) 

artworksPerCity = {} 

for stolenArt in data: 
    if stolenArt.has_key('Category'): 
     city = stolenArt['Category'] 
     if stolenArt.has_key('nItemsStolen'): 
      numbersStolen = int(stolenArt['nItemsStolen']) 
      if artworksPerCity.has_key(city): 
       # Adjust the value stored for this city 
       artworksPerCity[city] = artworksPerCity[city] + numbersStolen 
      else: 
       # Create new key with new value 
       artworksPerCity[city] = numbersStolen 
      # Draw circle on the map 
      radius = artworksPerCity[city] /2 
      x = xOfDot(stolenArt['Lon']) 
      y = yOfDot(stolenArt['Lat']) 
      arc(x, y, radius) 
      text(city, x, y) 

print artworksPerCity

ここでは、私は私の純粋なPythonのデータユーティリティに含める予定のもののスケッチです。

def hexidecimalDiget(n,deHex = false): 
    if(n<0): 
     print "negitive values not supported by call to hexidecimalDiget("+str(n)+")" 
     return None 
    elif(n < 10): 
     return str(n) 
    elif(n < 15): 
     return ["a","b","c","d","e"][n-10] 
    elif(n in ["a","b","c","d","e"]): 
     if deHex: 
      return ["a","b","c","d","e"].index(n) 
     return n 
    else: 
     print "call to hexidecimalDiget("+str(n)+") not supported!" 
     return None 

def colorFormHexArray(arr): 
    if len(arr)!=3 and len(arr)!=6: 
     print "invalid length for color on call to colorFormHexArray("+str(arr)+")" 
     return None 
    elif None in arr: 
     print "cannot make color from None arguments in "+str(arr) 
     return None 
    else: 
     ret = "#" 
     for k in arr: 
      if(type(k) == list): 
       for k2 in k: 
        ret+=hexidecimalDiget(k) 
      else: 
      ret+=hexidecimalDiget(k) 
     return ret 

def arrayFromColor(c): 
    c = c.replace("#","") 
    col = [] 
    for n,k in enumerate(c): 
     if(len(c) == 3): 
      col.append([hexidecimalDiget(k,deHex = True)]) 
     elif(len(c) == 6): 
      col.append([hexidecimalDiget(c[(n+1)*2-2],deHex = True),hexidecimalDiget(c[(n+1)*2-2],deHex = True)]) 
    return(col) 

def intFromHexPair(hp): 
    ret = 0 
    for n,k in enumerate(hp): 
     digBase = 16**(len(hp)-n-1) 
     ret+=digBase*hexidecimalDiget(hp[0],deHex = True) 
    return ret 

def hexPairFromInt(I,minDigits = 1,maxDigits = 256): 
    if I<0: 
     print "negitive numbers not supported by hexPairFromInt" 
    k= 0 
    while(16**(k+1) <= I): 
     k+=1 
    if k < minDigits: 
     k = minDigits 
    if k > minDigits: 
     print("maxDigitsExceeded") 
    ret = [] 
    while k>=0 
     dig = 16**k 
     ret.append(hexidecimalDiget(int(I)%(dig)) 
     I -= dig 
     k-=1 
    return ret 

def specColor(start,end,bottom,top): 
    start = arrayFromColor(start) 
    end = arrayFromColor(end) 
    def ret(v): 
     if(v<start or c>end): 
      print("value out of range "+str([start,end])) 
      return('#aa0000') #eyo <- error red 
     else: 
      starts = [intFromHexPair(k) for k in start] 
      ends = [intFromHexPair(hp) for k in end] 
      normalized = (v-bottom)/(top-bottom) 
      return colorFormHexArray([hexPairFromInt(int((starts[n]-ends[n])*normalized),minDigits = 1,maxDigits = 256) for n,k in enumerate(starts)]) 
    return ret 

これは、過剰なようだし、少しでもまだ（ちょうどstetchアップ気圧）をテストされていないが、私は今夜ここにこのコードをテストして組み込むことになります:: http://krewn.github.io/KPlot/
