See picture below. Chart is only showing 1 value along the X-axis, 10/9/2017. This field is a date field when the record was created. Not sure why the chart is only showing one date and not all of them.
Given that my crystal ball is once again down for repair, perhaps you could share what settings you selected for your chart, especially what you specified for the X-series?
What data source options are specified might also be helpful.
Well when looking to answer your question, I fixed it. Sorry for the inconvenience.
