Python code on CentOS
from pychartdir import *
# The data for the bar chart
data = [85, 156, 179.5, 211, 123]
# The labels for the bar chart
labels = ["Mon", "Tue", "Wed", "Thu", "Fri"]
# Create a XYChart object of size 250 x 250 pixels
c = XYChart(250, 250)
# Set the plotarea at (30, 20) and of size 200 x 200 pixels
c.setPlotArea(30, 20, 200, 200)
# Add a bar chart layer using the given data
c.addBarLayer(data)
# Set the labels on the x axis.
c.xAxis().setLabels(labels).setFontColor("0xcccccc")
# Output the chart
print("Content-type: image/png\\n")
binaryPrint(c.makeChart2(PNG))

I tried some other samples.
I found all the character can not display
This is another code in CentOS.And attachment is the chart.
from pychartdir import *
# The data for the bar chart
data0 = [100, 125, 245, 147, 67]
data1 = [85, 156, 179, 211, 123]
data2 = [97, 87, 56, 267, 157]
# The labels for the bar chart
labels = ["Mon", "Tue", "Wed", "Thu", "Fri"]
# Create a XYChart object of size 500 x 320 pixels
c = XYChart(500, 320)
# Set the plotarea at (100, 40) and of size 280 x 240 pixels
c.setPlotArea(100, 40, 280, 240)
# Add a legend box at (400, 100)
c.addLegend(400, 100)
# Add a title to the chart using 14 points Times Bold Itatic font
c.addTitle("Weekday Network Load", "timesbi.ttf", 14)
# Add a title to the y axis. Draw the title upright (font angle = 0)
c.yAxis().setTitle("Average\\nWorkload\\n(MBytes\\nPer Hour)").setFontAngle(0)
# Set the labels on the x axis
c.xAxis().setLabels(labels)
# Add a stacked bar layer and set the layer 3D depth to 8 pixels
layer = c.addBarLayer2(Stack, 8)
# Add the three data sets to the bar layer
layer.addDataSet(data0, '0xff8080', "Server # 1")
layer.addDataSet(data1, '0x80ff80', "Server # 2")
layer.addDataSet(data2, '0x8080ff', "Server # 3")
# Enable bar label for the whole bar
layer.setAggregateLabelStyle()
# Enable bar label for each segment of the stacked bar
layer.setDataLabelStyle()
# Output the chart
print("Content-type: image/png\\n")
binaryPrint(c.makeChart2(PNG))

Hi Marty,
Have you included the fonts subdirectory when you install ChartDirector for Python? If you do not include the ofnts subdirectory, the chart will not have text, because there are no fonts.
According to the Installation section of the ChartDirector Documentation, you should copy *everything* ((including the fonts subdirectory in Linux, FreeBSD and Solaris versions) from "ChartDirector/lib" to a directory in your Python module search path.
Please let me know if the above can solve the problem.
Regards

I copy the fonts directory to Python directory.
Then it works!
Thank you very much! |
