I suggest also this python library : <a href="http://matplotlib.sourceforge.net/">http://matplotlib.sourceforge.net/</a> <div class="gmail_quote">Le 25 octobre 2011 13:48, Miguel Colom <<a href="mailto:Miguel.Colom@cmla.ens-cachan.fr">Miguel.Colom@cmla.ens-cachan.fr</a>> a écrit : <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">> Hola Miguel, > > Probé de visualisar mis señales audio como puntos de una imagen > utilisando *Plotutils > Package*. > > Sabes si para IPOL hay que utilizar otro plot 2D ? Cual ? > > Mil gracias, > Eva. Hello Eva and everybody, I'll answer your question and also send it to the discuss list so everybody can know about it. For IPOL we'll have a standard way to create 2D plots. It have to be used the "draw2Dcurve.py" script. This scripts exposes a known interface that isolates the details of the drawing implementation (using GNUPlot, Matplotlib, C programs, etc). This script is only used in the dev. server right now, so before installing any demo that uses plots in the server, it has to be discussed where to store it. I leave this decision to the tech team. Right now the script is located at /home/colom/ipol/scripts/draw2Dcurve.py in the dev. server. The same file can be downloaded from <a href="http://dev.ipol.im/~colom/tools/scripts/draw2Dcurve.py" target="_blank">http://dev.ipol.im/~colom/tools/scripts/draw2Dcurve.py</a> If a demo in the dev. server whats to use it, it should execute /home/colom/ipol/scripts/draw2Dcurve.py and should NEVER make a copy the script. Creating a soft symbolic link is all right too. Of course, it can be downloaded and executed in a local environment to test it. The script accepts several options. I'll only explain those that need some explanation. Usage: draw2Dcurve.py [options] -h, --help show this help message and exit --output=OUTPUT output PNG file --title=TITLE title --xName=XNAME X-axis name --yName=YNAME Y-axis name --x0=X0 X-axis first value --x1=X1 X-axis last value --y0=Y0 Y-axis first value --y1=Y1 Y-axis last value --legend=LEGEND Legend for each data channel If legends are used, they will be put inside the plot. They must be separated by comma. Ex: --legend="Red,Green,Blue" --grid=GRID use grid --markers=MARKERS use markers To use/don't use grid and markers, these options must be set to 1 (activate) or 0 (don't use). --style=STYLE use custom line style It refers to the style of the lines. For every line, it has to be specified a color and a line style. For example: --style='r,-,g,-,b,--' would draw red solid lines, a green solid line and a blue dashed line. An example of invocation: draw2Dcurve.py combined.txt --legend='t-R,t-G,t-B,s-R,s-G,s-B' --style='r,-,g,-,b,-,r,--,g,--,b,--' --xName='Mean' --yName='Standard deviation' --title="Temp. series (t) and single im. est. (s)" --markers=0 --output=figure.png It draws a plot with 6 lines. The first 3 lines are red, green and blue solid and the other 3 red, blue and blue dashed. The input file format is: X1 X2 ... Xn Y1 Y2 ... Yn where each Xi is a column representing the X-axis values and the each Yi the Y-axis values. In <a href="http://dev.ipol.im/~colom/tools/scripts/example2DData.txt" target="_blank">http://dev.ipol.im/~colom/tools/scripts/example2DData.txt</a> there's an example of input file.
