Here we have a TPS load based (Alpha-N) map being viewed in 2d mode, but a bit more, now we can edit. The below shots are of the primary fuel map on a 6km file in the 500rpm range.

Here we simply have column/bar # 17 selected, the current method for displaying the selection is rendering a white checkerboard over the respective bar, the non-white pixels in the checkerboard are treated as transparent pixels, so the bar color shows through. Note the bar # and bar value (Inj ms) displayed in the upper left. Note this is not polished up, the font rendering is not proper and will be worked on shortly, as will the layout.

Below I've moved and enlarged the selection range using some keyboard keys to columns 9 through 23

Now the selected columns have been reduced by holding down a keyboard key.

Same selection, increased with holding down a different key.

Selection range has been moved to the left, no other changes.

Selection range has now been shrunk down to a single column again.

Those who have access to a GNU/Linux machine (Everyone has access technically! Get with the times people!) can download this test and try it out for themselves here:
