I have a problem that seems to me as a bug in the PowerBI chart visual.
I have a column that is defined as a decimal number. Then I have a measure that sums this column and is defined as a whole number (in the Modelling tab).
When I create a bar chart for the measure, the result in the chart is strange. Both 18 Jan and 19 Jan have the value of 12, however in the chart the size of the bars are different. Also the bar height difference between 2 and 3 and 3 and 4 is different. Look at the data table below.
