Scatter charts and X-axis legends and more...

[User (Legacy)]

Hi! 

I have many problems with ChartFX... 

Chart DLL, v. 4.0.16.0 

VC++ 6 

Trying to create scatter chart with date/time values on the x-axis. 

X-axis values are passed to the chart as double values (date/time values as 

in OLE variant). 

GetAxisLabel event is handled to convert double values to date/time strings. 

Then hText property is set (e.g. to "9.06.2000 12:00") 

Chart displays "9.06.20" instead !!! 

I found that this depends on _Decimals_ property, so if I set it to 3, the 

chart will display "9.00.200" ?! 

Don't you think this is stupid??? 

BTW, if I set decimals to a large number, say 1000, chart dll crashes, 

he-he. 

Where did you find such low-qualified programmers?? 

Another bug, SizeToFit periodically causes Divide by zero crash if the 

legend box is not visible. 

Many chart types still doesn't clip correctly (e.g. Curve and Area-curve 

charts, even Bar charts!!!). I posted this bug more than 3 months ago but 

it's still not fixed. 

Who invented that stupid way to get string properties? 

   char szBuffer[256]; 

   LPSTR lpsz = szBuffer; 

   m_pChartFX->get_HText(&lpsz); 

instead of simple 

   LPSTR lpsz = m_pChartFX->HText; 

which overwrites the application stack... 

I am very disappointed with ChartFX 98. 

I spent more than 80% of my work time investigating and avoiding chart bugs.
