Hello guys!
I have a problem that seems to be simple.
I need to display the table data in the image below, but in the first column there are equal data and for this reason the repeated data is not shown. In this example below I wanted a chart with 5 bars, but it is only showing 3.
You’ll still need to change the X-axis values in some way, then, or otherwise restructure your chart. JFreeChart, the underlying Java charting library we use, doesn’t allow duplicate keys.
