I was researching the animation features in teechart and came across some issues with what is included in the example features.

If you search on "animation" in the tee chart example features application, you get four results. I had problems with the following...

1) For the result "Series Animation," what is the pas unit that contains this example? I could not find it in the source code. I'm guessing it's named without the word animation in it.

2) For the result called Delay, when I click the animate/execute button nothing happens even after I played around with all of the settings. Is there something wrong with that code?

3) For the Video Creator result, if you click the start recording button, you get the following error "AVI Error: 8004406F."

A couple of additional questions:

4) Are there any other resources for creating a movie of your data? I did look at the "Welcome.pas" feature and am slightly confused about how the TTimer comes into play.

5) The Video Creator example states that "Videos can also be created with animated realtime charts or any other kind of multiple chart display." Regarding the phrase "multiple chart display," does that mean that I could create something like the four charts example, but have each chart animated, and have all four of those charts "playing" simultaneously and captured in a video?

Thanks!

Hello,

It's Tools_SeriesAnim.

I see the problem is Button1Click calls ChartTool1.Execute and then it calls StopAnimation method, that calls ChartTool1.Stop; so the animation is started but stopped too fast.
We'll try to correct it for the next maintenance release.

I can't reproduce this problem.

Welcome_All.pas uses a TTimer to add data to a series everytime the timer event is launched; this time depends on the timer interval.

The video tool is added to a Chart, so it can only record the chart it belongs to. However, a Chart can have multiple subcharts, and these subcharts would be captured by the video.
