Histogram display of date x-axis on Bar Charts
  •     Alk February 21, 2011 7:31AM
    Hello, I have bar charts which have the Date on the x-axis with the Date set to "histogram". Sometimes (eg, when there is a lack of space or there is a particular selection of the dates selected in the Devices Filter), the x-axis groups dates for each bar such as "30-Jan-2011 to 6-Feb-2011" and the bar next to it saying "6-Feb-2011 to 13-Feb-2011".

    This can cause confusion as it is not clear which dates in particular the bar is referring to.

    Is there any way to change the date labels so the dates do not overlap and it only displays what dates are inclusive in the bars, eg, showing "30-Jan-2011 to 5-Feb-2011" and "6-Feb-2011 to 13-Feb-2011" instead?

    This sounds like a glitch. Could you post a demonstrative IOK here?

    Hello Steve, I have attached below an IOK showing the issue and a screenshot with the problem on the x-axis.

    I am currently using the Omniscope 2.6-alpha b530 on a WinXP x32 system.

    Currently Omniscope uses "inclusive to exclusive" ranges for dates and numbers. We're looking into the possibility of changing this for dates and will post back here.

    Thank you. I look forward to a resolution.

    After some deliberation, we have decided to change the labelling of date field "buckets" shown at the bottom of Bar view histograms to be "[inclusive] to [inclusive]".

    This change has been made in 2.6 b534, available now from the daily builds section.

    The new format looks like the following examples:
    "1 Jan 2000 to 6 Jan 2000", "7 Jan 2000 to 13 Jan 2000", ...
    "2000 to 2004", "2005 to 2009", ...
    "Jan 2000 to Feb 2000", "Mar 2000 to Apr 2000", ...

    However we are keeping numeric fields in the "[inclusive] to [exclusive]" style:
    "0 to 5", "5 to 10"...
    "0 to 1000", "1000 to 2000", ...
    "0 to 500,000", "500,000 to 1,000,000"...
    This is to ensure that it is clear that numbers such as 4.5, 999.5 and 499,999.5 are included in the range, and because "0 to 500,000" is more readable than "0 to 499,999".

    Thank you very much Steve for the prompt replies and resolution as always.

    Yes, I understand about the numeric fields.
