Custom Report - Automatic Chart Selection for single dimension and measure should be bar

The above image is from the demo app, and I allowed Automatic Chart Selection. While the selection of Combo Chart is reasonable, I am unclear on why the measure is being displayed as a line. I'd suggest displaying a single measure/dimension combination as a bar unless the dimension is tagged as a date (in which case using a line is correct).

    Hi Or,
    As always your feedback is much appreciated!

    The auto-selection of charts is based on a number of factors (more specifically # of dimensions, # of measures, # values in the first dimension, and if it is a map or a date field). Each factor together with a "weight" then calculates a score for each available visualization compared to the other available alternatives. (Remember that not all visualizations are always available.) The highest ranking visualization get the honor of visualizing your data. :-)  

    We do not based on the data control the individual settings for the chart (such as selecting line or bar). In this particular case I agree it would make sense. But we could also easily end up with a very similar case where it would not make sense and trying to cover all scenarios would in the end add a lot of complexity to the code. (Making it more difficult to maintain and, more importantly, prone to unexpected (buggy) behavior.)
    ​
    For now we are reasonably happy with the balance of the selected visualizations and will not change it.
    ​
    Kind regards
    ​
    Michael
