Slow chart control creation

User (Legacy) · October 22, 2003

Hi,

I have noticed that when our application loads the first time a chart

control is created by the code

this.Chart = new SoftwareFX.ChartFX.Chart();

this line of code takes 5 to 6 seconds to execute (on a 1.5 GHz Petium 4).

Subsequent chart creations take negligible time. Is this normal? If not,

what could be causing this slow loading time. I think that maybe this did

not occur when we first started using the control, but now I am not sure.

Yes. The first call checks the license, which is then cached.

5 to 6 seconds is too much though, usually the license is checked in less

than a second and while it is true that the first chart takes longer than

subsequent charts the difference shouldn't be noticeable.

I think there is some problem with the license in your application.

Have you tried this app in a computer where Chart FX is not installed

(licensed) ?

Does it work the same way ?

To figure out what's going on, create a project from the scratch with a

chart in the main form and measure the time it takes to do

new Chart

Then put a button that does the same (new Chart) and measure that time. Run

this app from outside of Visual Studio.
