Large real time charts using dll

[User (Legacy)]

When I try to change the number of values in a realtime chart the chart area 

automatically changes its size on the screen. I change this by setting the 

MaxValues property to a new value. Because of this, when the chart area 

becomes too big, something happens and it shrinks into a single vertical 

line. 

I figure this has something to do with the CT_EVENSPACING flag. 

If I place the chart on the dialog in the resource editor I can set the 

number of values high but since I am creating the chart in runtime I have to 

change this property after creating the chart object and thereby reducing 

the chart to a single vertical line as mentioned before. 

My question is if there is some way for me to lock the size of the charting 

area so it does not change when I change the number of values? 

If not what method do you suggest for creating a real time chart with about 

5000 elements in runtime? If i exclude the CT_EVENSPACING flag the chart 

flickers and takes up 100% of CPU when the number of values exceed 600. 

I am using VC++ 6.0.
