as you can see at both attached images,
while i was trying to check the
according to “Chapter 3: Getting Started”
i received inverted plots..
This also happened during executing the example .m files…
I am also experiencing this problem.
I am using Matlab 126.96.36.1997 (R2009b) 64-bit (win64).
Can I safely assume it is becasue of our version of Matlab?
To add: When you save the image (jpg), the labels are correct.
Also, when using the arrows to cycle through classes, once in both axis the class is the same, the arrows become unresponsive and sdscatter has to be run again. I mention this here because I think this might be connected.
so far, we were not able to repeat this issue. On Matlab 7.9 win64 (Windows 7), sdscatter decision backdrop works fine - see the screenshot below. Do you use any extra settings in your Windows/Matlab regarding fonts, video acceleration?
It suggests that the flipping may be related to buggy handling of alphadata in some drivers.
To test if you’re observing the same issue, I patched the sdscatter code - please copy the attached file sdscatter.p to your perclass directory. When you open a new sdscatter with backdrop (using sdscatter(a,trained_pipeline) ), you should see much more vivid colors of the backdrop because no alpha is used. Does it affect the font flipping?
thanks for the quick reply.
This indeed fixed the problem of inverted fonts. I can live with vivid colors but better discernible titles ;-)
Aaaah, these ATI drivers, I thought they were only bad on Linux machines…
I ‘ll see if a newer driver version will help.
good to hear the flicker went away! I’ve prepare a fix that would allow you to switch the alpha on and off in an existing scatter. In this way, you may decide if you like to see the nice background color and maybe save the image for external use (another user above mentioned that saved images do not have flipped fonts).
The fix allows you to disable alpha by pressing the A key (capital A). The double buffer gets also switched on to avoid the flicker.
Just copy the two files to your perclass directory. The sdscatter.p only returns sdscatter to the state in the public release.
Could you, please, test if pressing A in the newly opened scatter plot corrects the font flipping?
