y軸の数値ラベルとtick、そしてy軸のラベルを打つ。そのために、drawVolumeLabels()関数を作成し、その関数内で、

for v in range(dataMin, int(dataMax)+1, volumeIntervalMinor): if (v % volumeIntervalMinor == 0): y = map(v, dataMin, dataMax, plotY2, plotY1) if (v % volumeInterval == 0): textOffset = textAscent()/2 if (v == dataMin): textOffset = 0 elif (v == dataMax): textOffset = textAscent() text(floor(v), plotX1 - 10, y + textOffset) line(plotX1 - 4, y, plotX1, y) else: line(plotX1 - 2, y, plotX1, y) |
として、グローバル変数volumeInterval = 10と、volumeIntervalMinor = 5で割り切れる値にtickラインを追加する。

最後にdrawAxisLabels()関数を追加し、X軸、Y軸のタイトルを、
