pyRMChart is an interface to DLL-verison RMChart(http://rmchart.com), which is a free, lightweight and elegant chart creator.
A sample code:
from pyrmchart import *nParentHndl, nCtrlId, nRegion1, nSeries1=1, 1, 1, 1
#************** Create the chart **********************
T=tRMC_CHART(10,10,600,450,AliceBlue,RMC_CTRLSTYLE3D, True)
nRetVal = CreateChartI(nParentHndl, nCtrlId, T,) #the shortcut of RMC_CreateChartI#************** Add Region 1 *****************************
T=tRMC_REGION(5, 5, -5, -5, r"Create via INFO\9bc", True)
nRetVal = AddRegionI(nCtrlId, T)#************** Add Series 1 to region 1 *******************************
aColor= Firebrick, LightSteelBlue, DarkGreen, LightCoral
aData=[10, 20, 30, 40]
T=tRMC_GRIDLESSSERIES(RMC_DONUT_3D, RMC_FULL, 2, True, RMC_VLABEL_TWIN)
nRetVal = AddGridlessSeriesI(nCtrlId,
nRegion1,
aData, #len=4
0, #you see, we use 0 here
aColor, #len=4 too
#0, #but we don't need this parameter
T=T
)nRetVal = Draw2File(nCtrlId, 't.png',)
nRetVal = DeleteChart(nCtrlId)
You can download ver 0.0.1 here: http://pyrmchart.googlepages.com/pyrmchart_0.0.1.zip
This pacakge is free even for commercial use, but you must make it clear in your manual that you used pyrmchart(http://pyrmchart.googlepages.com/) in your application.
Question: Is there other free chart tool or python lib that can create nice and modern chart?
I mean chart, so matplotlib is not the answer.
I said "nice and modern", so I don't think http://home.gna.org/pychart/ and http://graphite.sourceforge.net/ fit.
And I don't like JAVA and .NET
