Re: TeeChart displays extremely slow in cxRTTIInspector

Hello Narcis, the DevExpress RTTIInspector has a filter event where properties can be excluded from loading. They told me that this would indeed speedup the loading process. In general, only a few properties needs to be accessable by the user. This is especially true at TeeChart, where most settings...

TeeChart displays extremely slow in cxRTTIInspector

In a project where the customer must be able to change component properties at runtime I use the DevExpress RTTIInspector. Normally changing components that are to be displayed there takes no time. Whenever a TeeChart ist displayed (cxRTTIInspector1.InspectedObject := Chart1) it takes several second...

Re: Polarseries draws unwanted line

Hello Narcis,

here is the requested sample project.
It seems that the line is only drawn if the angle offset is not zero.
The project was compiled with Delphi XE7 using the latest TeeChart.

Regards Gerhard

Polarseries draws unwanted line

Hello, on the attached jpg it can be seen that the chart contains a line from the center of the circle at about 20°. This line is the first out of about 800 segments. Before anything is drawn, I set the axis with the following lines, mb is 500. SMEChart.LeftAxis.Automatic := false; SMEChart.LeftAxis...

Re: Polar series is not circled

In my case the Problem occured only on VirtualBox PCs.
I replaced all Virtualbox Systems by either VMare Workstation or VMWare Player.
Since then the Problem is gone.

Re: Floating point error

Hi Yeray, I already had problems with axis scaling when Setting min and max values separately. This is the reason why I use only the SetMinMax function, I never had problems with it. But in the current Situation I tell TeeChart to scale the Y axis by itself. This works well in most cases but not alw...

Re: Floating point error

Hi Yeray, my application is a rather big Project, it is not easy to pull parts out. You expect me to invest a substantial amount of time to an example without knowing if the Problem shows up there. Time that I do not have, sorry. I think I already gave you a lot of Information, more is currently not...

Floating point error

in my application a teechart is place on a frame. Multiple instances of this frame are placed on a vcl form dynamically. The charts are placed and initialized on the forms constructor. Later the charts get their xy values, axes are scaled either manually or automatic and so on. Sometimes I get an er...
