The LabelFormat question is solved Victor! Thank you by the helpful answer.
On the question of value limit, I meant that the value of point is exceeding 10 million. So, it doesn´t allow the correct visualization of the numbers in the LinearAxis.
How sample, a datapoint have the category "Jan", and the value 10 000 000. Because of this, I need do a conversion, dividing this value to plot in the chart. Is there a value limit to plot points in the chart?
Also, I noticed that values broken doesn´t appear in the LinearAxis. I´m using the method Math.Round() .
