Thanks everyone for sharing your thoughts. I agree that this cannot be simply done by controlling data - it seems that by default axis data is assumed to be continuous, which will produce visual gaps on the chart if actual data is not continuous. Creating separate plots and placing them side by side with no margin would be ok for a static plot, however I am using these dynamically, so that won't work unfortunately. Unless I am missing something of course. By "using dynamically" I mean that I am panning/zoomng/scrolling the data a lot, adding new data sets on the same plot etc.
After an initial look it seems to me that it's not an Axis but the Viewbox that controls value ranges. If I understand correctly, the AxisItem controls presentation, not the underlying axis data. I can't say I am too familiar with how Viewbox works yet, but it seems to be built around an assumption that values are continuous in either linear or log fashion. There are numerous places in Viewbox code where xrange/xlimit is used, which suggests to me that whatever is within range/limits must be continuous (or is assumed to be). I will continue to look into this, any tips are welcome.
