Has anyone else noticed a problem when saving an image (png) on windows. Hard to describe, .. but it seems that if there is lots of data to plot and window size too big, or maximized, it cannot save the full plot data stopping half way. (plot look fine on window). .... Interesting reducing the window size can get to the point where can save the full image. Good plot (small window size) http://members.optusnet.com.au/~steve_geo/MatPlotLibTests/12p5KInternalIR_InputGndGood.png Failed plot (larger window size) http://members.optusnet.com.au/~steve_geo/MatPlotLibTests/12p5KInternalIR_InputGndFailed.png I get the same problem on two different systems: Windows XP & Python 2.4 & matplotlib & numarray 1.5.2 matplotlib installed from matplotlib-0.87.6.win32-py2.4.exe matplotlibrc has backend : TkAgg Windows 2000 & Python 2.5 & matplotlib & numpy 1.0 matplotlib installed from matplotlib-0.87.7.win32-py2.5.exe matplotlibrc has backend : TkAgg find my data here http://members.optusnet.com.au/~steve_geo/MatPlotLibTests/ScanDataInternalIR_GndInput.log and the script here (only tested with numpy and numarray) http://members.optusnet.com.au/~steve_geo/MatPlotLibTests/irplot24.py the command to reproduce the test is irplot24.py --second=fft --target=600000 ScanDataInternalIR_GndInput.log ================= Also it's also interesting to note the difference in load time (sec) of the data between numarray and numpy for the same data. Windows 2000 & Python 2.4 & matplotlib & numarray X:\srg\MatPlotLibTests>c:\python24\python ..\irplot24.py --second=fft --target=600000 ScanDataInternalIR_GndInput.log Importing pylab library ........ 1.685 Opening file and loading array . 3.999 Windows 2000 & Python 2.5 & matplotlib & numpy X:\srg\MatPlotLibTests>c:\python25\python ..\irplot24.py --second=fft --target=600000 ScanDataInternalIR_GndInput.log Importing pylab library ........ 0.882 Opening file and loading array . 10.687 Thanks for any comments Steve |
