bar charts with time axis #173

Your bar chart numbers the bars from 0 to n (on x-axis). Would it be possible to recognize dates as x-axis ? It'd be also useful if I could specify the width of every bar (or distance between 2 bars), so that the extraction algo doesn't miss any. Thanks and regards Daniel.

If the x-axis is uniformly spaced in time, then you can try calibrating the chart as a 2D XY chart and then using the "Histogram" extraction method as mentioned here: https://automeris.io/WebPlotDigitizer/blog/posts/bars.html

This could possibly be achieved by something like a solution to #74.
