Saving Chart Templates

[User (Legacy)]

Francisco,

We are struggling with our implementation of saving a chart layout that can 

be recalled and applied to a chart with updated data. We have most of it 

working well, but have not figured out a couple of things....

1) If we have the stat extension turned on, we can save the fact that it is 

on, but have not figured out how to save the visualizations that a user had 

checked (i.e. mean, median, etc.) We have turned on the Reuseextensions 

string, but that has not helped.

2) When we repopulate the chart, we are grabbing the saved template (we are 

storing it in an XML stream) and then applying the new data from the 

database.  We have a sitaution where the user may have originally had a 

chart with two series (i.e. unique users and web hits). After saving the 

template with those selections they may update the chart with a modified 

selection (i.e. sales and web hits).  The chart shows the right data, but 

the legend still reads (unique users and web hits).

We can not figure out which bits to turn on/off in the FileContents string 

to make it so the chart will show the new data, respect all of the per 

series and per attribute setting AND still reflect the appropraite (new) 

legend entries.

It may be that we have to override certain settings after we apply the 

template & data. Any thoughts?

Finally just for our benefit..in the FileContents string...can you describe 

in more detail what chart properties are included in the "Titles", "Text" 

and "ReuseExtensions" bits?

Thanks.

We discovered a bug a few days ago in which the Visible Property for a Study 

was not being serialized correctly into an XML. This seems to be the same 

problem you are having. This fix will be included in the next Service Pack. 

You can contact Software FX Support to obtain a HotFix.

While the data is not saved into the XML, the series attributes (along with 

the legend text) is. FileContents.SeriesAttributes controls this but it is 

an all-or-nothing setting. You either save ALL series attributes (Color, 

Text, etc.) or none. There is no way to selectively select which attributes 

to save.

The ReuseExtensions flags does NOT change what gets saved, it simply 

instructs Chart FX than when reading a file to re-use the same extension 

objects already attached to the chart (if they are there) instead of 

creating new instances of them.

FileFormat.Titles: Saves the titles (Chart titles, Axis Titles, Pane 

Titles). The attributes of each title would be saved depending on the other 

FileContentSettings. For example the Text of the title will be saved only if 

FileContents.Text or FileContents.TitlesText are on.

FileContents.Text: Saves axis labels, custom gridlines labels, and title 

text.
