Hallo,

we have the following problem: To interrupt lines (class Series) in a TChart we use an implementation to add transparent points between points which should not be connected. This works quite well for the chart in the UI.
But if we export the data from the chart we see these transparent points in the data.

My questions now are:

Is it possible to modify the export functionality not to export e.g. transparent points?

Is there another possibility to create lines where in some cases one point is not connected with the following one?


A solution with two or more lines would probably be very complex to implement.
I searched in the internet and did not find answers there. So I would kindly appreciate any support.

Kind Regards

Jens

In what format are you trying to export your chart?

Please take a look at this thread where the same question was discussed:

Hi Yeray,

we try to export the numbers in different text formats. I think the first thread you mentioned does not help for this case, since its issue is a transparent chart background.

The second thread you mentioned exactly describes the solution we use here to interrupt lines in charts. But as we found out the transparent points created here are exported when exporting data as text. The user does not want to see these points in his results.
Do you agree that this is a kind of missing functionality in TChart or a bug?
Or is there a workaround possible?

Regards

Jens

Hi Jens,

Oh, I think I misunderstood you. Here it is a thread where a similar situation was discussed:

Hi Yeray,

in the thread you mentioned in your second reply it is proposed to export the data manually not with the TChart export functionality. This is in my opinion a workaround and not a real solution.

So, do you agree that it is some missing functionality in TChart to export discontinued lines?

My colleagues and me we have the request to add some functionality to exclude transparent points from export or to find another solution to export discontinued lines with the TChart export tool.
What is your opinion? Could you enhance this in future versions?

Kind regards

Jens

Hi Jens,

I've added to the wish list the possibility to have a property (that could be named IncludeNulls, for example) to choose if you want the nulls to be exported or not (TF02015129).
