Bug with snappable plots in log scale

[gdargaud]

Hello, hello,

I found a weird behavior, maybe a bug.

If you have a cursor and a snappable plot on a graph with an axis (say Y for the sake of argument) both with log scale and auto-scaling, the topmost points cannot be selected by the cursor, either with the mouse or the keyboard arrows.

If you add an invisible and non-snappable point to the graph at MaxY*1.0001, then it works...

Hi gdargaud, 

What I have found from another forum post is that you can configure whether a cursor can snap to a particular plot by setting this plot attribute:

SetPlotAttribute (panel, graph, plot, ATTR_PLOT_SNAPPABLE, 0;

It might have expected hidden plots to not be snappable by default, but apparently, they're not, so you'll have to also set this attribute whenever you hide a plot.

Try to set the plot attribute and then try snapping those points again. 

Regards)

Yes, I imagine the snappable+hidden combination might come in handy in a few cases (although that could be replaced with a transparent plot), but I don't think it has anything to do with the bug I noticed.
