Problems with setNumberFormatOverride

[merlushatrash]

Sometimes I am getting only one point in a graph to display.
If it is only one point there is no TickUnits,except for really large values.
Second problem when is only one point in a graph zooming is not working correctly and really slow. (Generates exception )
Third one if I even set up number format setNumberFormatOverride, after zooming TickUnits are not displaying in desire format.

Does someone can tell me how to fix these problems or it is better way to submit bugs and wait until they will (or won't) be fixed

This is related to the axis trying to determine the 'automatic' range that will incorporate all data points. When there are at least two points, it is easy - we take the min and the max, and add a small margin to ensure that those points are not hard up against the edge of the chart.

But when there is only a single data point, what should be the axis range? Should it be x-1 to x+1? Or x-0.1 to x+0.1? Or...? There's no right answer, so we make it configurable via the ValueAxis.setAutoRangeMinimumSize() method.

Thanks, for answer.
How I can set up Number format that will be the same even after zooming?

[paradoxoff]

The "Number format" won´t change with the zooming if you are using a NumberFormatOverride.
Just check the stack trace and have a look at the code: the error comes from a ValueAxis having the same value for the lower and upper bound.
Re-read Davids post, then try calling ValueAxis.setAutoRangeMinimumSize(1.0);

[merlushatrash]

Thanks for answer. I will try.
