I'm running the ChartBrowser Sample(v20.2) and it hangs when selecting charts like Line Styles, Lines, Spline, etc.

I checked and an infinite loop occurs in CXTPChartDiagram2DAxisView::CreateTickMarks.

An overflow occurs here and it is changed to a negative value, resulting in an infinite loop.

CXTPChartDiagram2DAxisView::CreateTickMarks(

...

while (dMark < dAxisMaxValue + CXTPMathUtils::m_dEPS)

{

...

// Here it is changed to a negative value.

dMark *= m_MarkCorrectionCoef;

dMark = CXTPMathUtils::Round(dMark);

dMark /= m_MarkCorrectionCoef;

In this case, the values were:

double dViewMaxValue is 40431.5999

m_MarkCorrectionCoef is 1000000

dMark is 2852.516352 => 2852516352 => -2147483648.0000000 => -2147.4836479999999

This value is repeated over and over again.

And when changing the chart style, the following exception occurs.(multiple lines)

Exception thrown at 0x00007FFFFEFC4F69 (KernelBase.dll) in ChartBrowser.exe: 0xE0000001 (parameters: 0xFFFFFFFF80004005).

It's been a known issue and it had been fixed for the next maintenance update v20.3 which will be release soon.
