I draw plot based on JSON data source:
But before data presentation, I need to divide every values by 500, so I need see on chart for example value "7 260.236", not "3 630 118"
How to calc it on the fly before chart presentation?

I'm building a regression visualiser and can plot the original data and calculate the regression model. For fitting, I'd like to include predictions for the whole chart axis range available, not only the original data range.
Creating the empty chart sets xAxis 0 to 110 by default.
Then I'm plotting the data:
How can I access the visible xAxis extreme values, and especially the upper 5.5?
Trying xAxis.getUpperBound gives the original 110.
When I'm using Excel I can insert a label on my scatter chart data points, but Google Data Studio only wants me to change the color of the points, I not found any documentation about how insert labels on the points, anyone has idea?
Its at the top of the Style section
I am using jasper reports with charting. The chart generally works with a wide variety of values.
In one case the values are either 1.011 or 1.01 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 1.01.
The challenge is, when generating a chart with these values, 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 fall off 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
My data is xy rings with z as a height. I create a contour map of the data. I need to be able to create xy data points with the z component having a value somewhere between the 2 contour lines. Then extract all of the xyz data. I have found a few programs to extract the data but it is only x,y data and it is basically the xy data that I originally started with.
