Re: [Matplotlib-users] save or pickle figure object

We have some experience maintaining persistent object storage over long periods of time. The best solution we've found is to do something like this: - create a read/write method on each class. Every class that needs to be stored must have this. This includes class you would store (eg Figure) an

Re: [Matplotlib-users] Toolbar in QT

The toolbar is just a widget so you can do that the same way you show any other widget in Qt. Something along the lines of: - build a widget - add a layout - add the figure widget to the layout - add the toolbar to the layout - connect them tog

Re: [Matplotlib-users] PNG filesize

I'd guess PNG won't get much smaller because you have a lot of different colored pixels. PNG compresses most when you have a sparser plot. I'd suggest that you try using JPG. It will compress the multi-colored portion of your plot way down. You may see a few artifacts if you look carefully at t

[Matplotlib-users] Efficient scatter() w/ markers from plot()?

I need to efficiently plot a set of x,y points where each point has a different color. I tried multiple calls to plot() with a single point each but that is way too slow. I switched to using scatter() and passing in a list of colors which works great. However, I'd really like to have the marker

[Matplotlib-users] Create powerpoint slide and/or presentation from script?

Does anyone know of a way to create a powerpoint slide from a plot? I'm assuming that it's possible to have a script that savse a PNG of the plot and then use a VB (or preferably python) script to create a slide (or append that slide to an existing presentation). I've google'ed around but I'm

I don't think so. We always manually check for horizontal and vertical axis crossings and split the line as many times as necessary. At 03:31 PM 8/2/2007, James Boyle wrote: >This is probably for Jeff but maybe someone else has an answer. >If I plot a satellite orbit on the globe when the ground

Re: [Matplotlib-users] AttributeError: LineCollection instance has no attribute 'get_lines'

John, One of the problems we've had is trying to design an auto-scaling algorithm that works well with any type date format since the date strings can be so large horizontally. I believe that having the draw time elements be able to query the renderer for things would help this out tremendousl

Re: [Matplotlib-users] spy ignores negative values?

John, One small note - we've been bitten in the past by doing: x != 0 This assumes a numeric (int/float) quantity. If someone substitutes a different type that looks like a number, this will most likely fail. Python has a __nonzero__ method which can be used by calling 'not' or 'bool()':
