我正在生成甘特图来表示家具厂生产线的机器占用。它有几台机器和机器并行工作，全职（或几乎）。

我为 Python 找到了这个库（Chart-Director）并成功安装并运行了示例代码。

# data for the gantt chart, representing the start date, end date and names for
# various activities
startDate = [chartTime(2004, 8, 16), chartTime(2004, 8, 30), chartTime(2004, 9, 13),
    chartTime(2004, 9, 20), chartTime(2004, 9, 27), chartTime(2004, 10, 4),
    chartTime(2004, 10, 25), chartTime(2004, 11, 1), chartTime(2004, 11, 8)]
endDate = [chartTime(2004, 8, 30), chartTime(2004, 9, 13), chartTime(2004, 9, 27),
    chartTime(2004, 10, 4), chartTime(2004, 10, 11), chartTime(2004, 11, 8),
    chartTime(2004, 11, 8), chartTime(2004, 11, 22), chartTime(2004, 11, 22)]
labels = []
for i in range(0,9):
    labels.append("Maq" + str(i))

# Create a XYChart object of size 620 x 280 pixels. Set background color to light
# blue (ccccff), with 1 pixel 3D border effect.
c = XYChart(1080, 640, 0xccccff, 0x000000, 1)

# Add a title to the chart using 15 points Times Bold Itatic font, with white
# (ffffff) text on a deep blue (000080) background
c.addTitle("Simple Gantt Chart Demo", "timesbi.ttf", 15, 0xffffff).setBackground(
    0x000080)

# Set the plotarea at (140, 55) and of size 460 x 200 pixels. Use alternative
# white/grey background. Enable both horizontal and vertical grids by setting their
# colors to grey (c0c0c0). Set vertical major grid (represents month boundaries) 2
# pixels in width
c.setPlotArea(140, 55, 900, 500, 0xffffff, 0xeeeeee, LineColor, 0xc0c0c0, 0xc0c0c0
    ).setGridWidth(2, 1, 1, 1)

# swap the x and y axes to create a horziontal box-whisker chart
c.swapXY()

# Set the y-axis scale to be date scale from Aug 16, 2004 to Nov 22, 2004, with ticks
# every 7 days (1 week)
c.yAxis().setDateScale(chartTime(2004, 8, 16), chartTime(2004, 11, 22), 3600)

# Set multi-style axis label formatting. Month labels are in Arial Bold font in "mmm
# d" format. Weekly labels just show the day of month and use minor tick (by using
# '-' as first character of format string).
c.yAxis().setMultiFormat(StartOfMonthFilter(), "<*font=arialbd.ttf*>{value|mmm d}",
    StartOfDayFilter(), "-{value|d}")

# Set the y-axis to shown on the top (right + swapXY = top)
c.setYAxisOnRight()

# Set the labels on the x axis
c.xAxis().setLabels(labels)

# Reverse the x-axis scale so that it points downwards.
# c.xAxis().setReverse()

# Set the horizontal ticks and grid lines to be between the bars
c.xAxis().setTickOffset(0.5)

# Add a green (33ff33) box-whisker layer showing the box only.
c.addBoxWhiskerLayer(startDate, endDate, None, None, None, 0x00cc00, SameAsMainColor,
    SameAsMainColor)

# Output the chart
c.makeChart("gantt.png")

此代码输出当前图像： 在此处输入图像描述

这样一来，就好像每台机器只能成为流程的一部分，但事实并非如此。换句话说，我想让每台机器大部分时间都在忙碌，所以我需要在每“行”中绘制几个“块”，但我找不到这样做的方法。

我已经尝试创建startDate为日期列表的列表，但出现执行错误：

startDate = [[chartTime(2004, 8, 16), chartTime(2004, 8, 30)], chartTime(2004, 9, 13), ...

我挖掘了一点，发现可以创建多层图表： http: //www.advsofteng.com/doc/cdpython.htm#layergantt.htm

但是要知道何时需要添加另一层，这样做会非常复杂。

有没有更简单的方法？有没有其他图书馆可以让我这样做？

谢谢你。

这是一个基于公司的答案，但是您是否已经尝试过 VARCHART XGantt ( http://www.netronic.com/products/varchart-xgantt/overview.html )？它非常灵活，可以做你需要的。
