On redrawing graphs when saving a presentation

Aspose.Slides Product Family

Hi.

When saving a presentation, each graph etc. redraws the graph based on the reference data.
Although it may be troubled if redrawing places that are not touched
Is there a way to not redraw in the option when saving?

I have observed your comments. Can you please share source presentation, generated presentation, source code along with environment details so that we can further investigate to help you out. Also please share which Aspose.Slides version you are using on your end.

Hi.

Version of Aspose is 17.10.0.0

There is a pie chart in the attached file, and this is a graph showing the current display
The value of the data source (reference source Excel) of this graph is different
It is best to correct the data source correctly in order to display it as shown in this graph.
That is, the diagram of this graph is now incorrect.

But as long as you do not display data source filter or reference source Excel,
The graph will never be redrawn (it will not be redrawn when saved in microsoft.powerpoint)

//----- soruce
var presentation = new Presentation(pptPath);
presentation.Save(pptPath, Aspose.Slides.Export.SaveFormat.Pptx);
//-----

However, opening this file with Aspose and just saving will redraw the graph.
I think that this is correct as it is just common sense to redraw according to the data source,
Those that does not change even if it is saved with microsoft.powerpoint, is a problem of why Aspose will change without permission.

best regard.
