I have a report with a chart. Generally a wide variety of values are successfully displayed on the chart. In one case the values are either 1.011 or 1.012 for the range or Y axis. That is, the user tries to generate a chart and some of the values are 1.011 and some are 1.012. The challenge is, the chart is scaled incorrectly on the range or Y axis. The labels range from 1.000 to 1.010 with increments of .001. As the top of the chart is 1.010, the values 1.011 and 1.012 fall off of the top of the chart and don't appear on the chart. Can anybody explain how the range or Y axis is derived beyond stating that the axis is derived from the data. And why, in this case, is the axis derived incorrectly? Is there a way to configure the chart to display the range or Y axis more correctly I edit a jrxml file. I do not use iReports or java api. Thanks for all of your assistance and good ideas
