[Need advice] Incrusting a TChart on another TChart...

[bertrod]

Hello,

For my customers it's a need to be able to view a chart over another one like my example below :



I'm thinking about 2 possibilities :

1. Adding a TChart component on the main TChart, but the problem is to be able to save the image as GIF, JPEG, etc. correctly (with the 2nd little chart).

2. Creating a new component which inherits from TAnnotationTool, and draw a TChart component inside the derived TAnnotationTool, but it seems quite difficult to realize.

Do you have some suggestions for my problem ? If you think it's possible, you could add this to your wish-list.

Hi bertrod,

For v8, which is the version we are currently working in, we implemented some features to support more multiple charts combinations.

In the meantime, you could either try using:

- Just drop a smaller chart above the bigger one.

- Use a TChart for the big chart and use an invisible chart to draw the small one, export it to an image and embed it into the bigger one using an image tool.

Hi Narcis,

- putting one chart above a bigger one is a problem because the little chart will not be visible when exporting as GIF, JPEG, etc.

- using a TImageTool is the best solution I see, but it involves some modifications in TeeTools.pas to make the TChartImageTool do what I want.

Do you have an idea when the V8 of TChart will be released ? If it's not too far from now, maybe I can wait.

Hi bertrod,

I don't know when it will be out exactly. However, we currently have a beta version available. If you are you interested on it we can send you the information to download it.
