Hi,

I've found a problem with TFastLineSeries(A) that uses another TFastLineSeries(source) as a DataSource.
If A has DrawAllPoints set to false and source has less than 2 points then an access violation is thrown
everytime the chart is drawn.

I've included a small sample project with this setup.
I tested it on my current setup and teechart that came bundled with Delphi XE, the bundled
version worked OK.

Please note that I have found a workaround where I disable DrawAllPoints when the source
series has fewer than 2 points.

Using
Delphi XE with Update 1, 15.0.3953.35171
TeeChart Pro v2011.04.41118 32bit VCL

Hi,

Also if you resize the chart smaller, so that the left and right axis touch, theres an access violation.

I've decided not to disable the DrawAllPoints since it's more trouble than it's worth.

You are right. I've added it to the defect list to be fixed in future releases (TV52016054).

You are right again. I've also added it to the defect list to be revised fr future releases (TV52016055).

Hi Kjaran,

This is to let you know I've just checked any of the problems (TV52016054,TV52016055) aren't reproducible any more with the actual v2012.07 version.
