SerialPlot 0.10 is released. This release brings some performance improvements, minor features and bug fixes.

Instead of "number of samples" option in the "Plot" tab, now there are 2 options you can set. "Buffer Size" and "Plot Width". "Buffer Size" is the total number of samples that are kept in memory, while "Plot Width" is the maximum number of samples that are plotted at once, in X axis. To see previous samples you simply use the X axis scrollbar. The main reason for this distinction is the performance. Previously you couldn't set number of samples too high because SerialPlot tried to plot all data at one time. Now you can set "Buffer Size" to 1.000.000 and it will most likely will be fine as long as you keep "Plot Width" small. Another advantage is that, sometimes when you have frequently changing data, zooming way out doesn't mean much, you have too keep a certain zoom level in X axis to be able to see any detail. If you enjoy the old behaviour you can always set buffer size option same number as plot width and it should be fine. Remember though "plot width" option has a smaller limit then "buffer size" for performance reasons. A note; performance improvements are not done. I'm still working on some improvements to increase "buffer size" limitations.

Now you can set RS232 control signals (DTR, RTS) and see input signal () statuses from the "Port" tab. Being able to set DTR signal was a requested feature so that SerialPlot can work with Arduino Leanardo board.

Also we now have an update checker. You can launch it from the "Help" menu. It will check updates once a day when you first launch SerialPlot unless you disable it.

Other improvements and bug fixes:

Check the sidebar for download links. I will try update the win32 version and launchpad PPA later this week.
