Is there a way to make the TChart it self transparent? For example, if I drop two TChart frames on a form, and have the two charts overlapped. Can I set the TChart property so that curves from both charts are displayed, rather then on e chart is covered by another chart?

Thanks

Hello Bill,

Yes, here you'll find an example on how to make a transparent chart.

Hi,

I've searched the posts and have not found an example that shows me how to make the Chart transparent.

Hi Bill,

It's an attachment at Yeray's 31st July 2009 post.

Thanks for the post. The example worked with the TMapSeries. However, if I change to a TFastLineSeries, and try to zoom or panning, as you can imagine, the result is not desirable. IS there a way to pass the background Canvas and draw on that? Can that be a solution?

Thanks.

Hi Bill,

I made an example with a FastLine series, find it attached. I removed the chart, added a new one, assigned the OnBeforeDrawChart event and hide the back wall. Does this work as you expect?
