[sage-support] Re: Superimpose various region_plot's
On 7/14/10 11:27 AM, David Sanders wrote: I have been playing with this a bit, and have found some problems. Firstly, with this code it seems not to be possible to make a region_plot *without* specifying opacity -- it looks like a default argument is missing somewhere. I've noted this on the trac ticket; thanks. But the main problem is the same one as I started with. Currently, each region_plot paints the part which is not "inside" the region in white (by default), as opposed to leaving it "blank". This means that when opacity != 0.5, the second plot drawn still partially hides the first. Ah, so outcol should by default be set to a 100% transparent color? I'm having difficulty getting matplotlib to draw a contour plot with a color map where one of the colors is transparent. My preferred behaviour would be simply to not draw anything if, for example, outcol == None. Perhaps this is not the right place for this discussion (is that the sage-devel list?), but I tried to modify the code to do this, by checking for outcol as follows: if outcol: g.add_primitive(ContourPlot(xy_data_array, xrange,yrange, dict(contours=[-1e307, 0, 1e307], cmap=cmap, fill=True, **options))) else: g.add_primitive(ContourPlot(xy_data_array, xrange,yrange, dict(contours=[-1e307, 0], cmap=cmap, fill=True, **options))) (I also checked for it where it is converted to an rgbcolor.) So if outcol==None, then it should only fill the negative region, which corresponds to where the arguments are true. However, I never got this to work, apparently because I don't understand properly what the cmap object does and how it works. Directly in matplotlib I did manage to do what I wanted, but not specifying a cmap. Here I can't seem to get it quite right, but it seems to me like this is the right direction to go in. Can somebody enlighten me on cmap? (yes, I know this is an old thread---I'm catching up...) How did you get it to work in matplotlib? The documentation for matplotlib cmaps (i.e., "color maps"---classes that convert a scalar to an rgba color with transparency) is here: http://matplotlib.sourceforge.net/api/cm_api.html See also: http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.Colormap http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.LinearSegmentedColormap http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.ListedColormap Thanks, Jason -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

After the crash, when a new Sage instance is started, nothing is defined anymore, of course, so it appears the workspace was trashed. No, it seems to go beyond that. Even when I evaluate a cell containing the number 1 or a string (so, no variable), there is no output. And it can not be the reason that there is an undefined variable: There is no output *and* no error. Nothing. Even if in a subsequent cell I use a clearly non-existing variable, there is no NameError. Then it seems like the Sage instance crashed, and so is not responding, doesn't it? That has been my experience when I've seen these symptoms---the backend Sage instance crashed and stopped responding to the server's requests. The worksheet indicates that it is busy working (by alternating / and \ appearing in the page title), but it still accepts input. That is your web browser doing those things. The backend Sage instance doing the computations isn't affecting those functions.

I suggest that the following guideline could be added to the documentation (http://www.sagemath.org/mirror/win/README.txt): * download VMware - please check around every three months whether there is a new WMware version! Currently use version 3.1. * start Sage * If it works correctly, you see three icons: Sage notebook, Sage and Terminal i) Start Sage notebook ii) you will see a web-address message like http://192.168.231.12x/. Remember it! - if you do not see a web-address message, you can use Sage within Ubuntu but you cannot use Sage in Windows Now do some quick tests, mainly to ensure that the system settings are optimal. iii) Open the worksheet Test. Check whether all calculations and graphics work properly and fast(!) - if no reaction: please notify sage-support with all the information about your system, error messages et cetera - if graphics does not show up nicely: install missing software and/or try different screen settings - if Sage is slow, please notify sage-support with all the information about your system iv) Close the worksheet Test, close Sage notebook, close VMplayer v) Open VMplayer directly (search for VMplayer.exe) - You will see the virtual application Sage. - If you point to it, on the left screen you are able to change the memory settings. Go for the max! - start Sage application (nothing else!), and minimize the screen - start your web browser (Firefox 3.6 or better), and use the address 192.168.231.12x - check Test again The Sage world is yours! When a release is made, the above steps should be tested. * The main reason for the extra steps is that VMplayer now allows a different memory allocation per application, but standard is 512MB. If I can contribute further, please let me know.

Thanks in advance! Here is a little experiment I ran: I just tried to change the RAM allocation for the latest vmware image, and could not. At the top of the corresponding settings window, vmware tells me: "Disabled items cannot be changed until the virtual machine is powered off. To make these changes, first resume the virtual machine and then shut it down." In other words, one cannot change the RAM allocation for a virtual machine that is currently running or suspended, but only for machines that are powered off.

First, the setup: Sage Version 4.3 VirtualBox 3.1.4 Windows 7 Firefox 3.6.8 My machine crashed with the VM running Sage. When I rebooted, I restarted VirtualBox, restarted the VM, and pointed the (host) browser to Sage's IP (192.168.56.101). No dice: I get a "Firefox can't establish a connection to the server at 192.168.56.101." Furthermore, pinging 192.168.56.101 from a command prompt gives 4 healthy <1ms responses. Inside the VM, opening Firefox and pointing it to http://localhost:8000/home/admin/ initially gave a "can't establish connection" error. Then I clicked on the "sage:prompt" icon and typed "notebook()". The result was that now the VM browser does display the "Active Worksheets" page correctly, although Sage threw the following at me: The notebook files are stored in: sage_notebook.sagenb ** ** * Open your web browser to http://localhost:8000 * ** ** Removing stale pidfile /home/sage/.sage/sage_notebook.sagenb/ twistd.pid 2010-08-11 13:11:24-0700 [-] Log opened. 2010-08-11 13:11:24-0700 [-] twistd 8.2.0 (/sage/sage/local/bin/python 2.6.2) st arting up. 2010-08-11 13:11:24-0700 [-] reactor class: twisted.internet.selectreactor.Selec tReactor. 2010-08-11 13:11:24-0700 [-] twisted.web2.channel.http.HTTPFactory starting on 8 000 2010-08-11 13:11:24-0700 [-] Starting factory The host browser still does not see 192.168.56.101.
