Excel, PowerPoint and C#

After I copy the chart from Excel to PowerPoint, I want to re-size the chart object.

shapeRange.Height = 250.5F;
shapeRange.Width = 100;

But the above is not working because the "Lock aspect ratio" is selected by default.
I don't know how to disable the "Lock aspect ratio" so that I can change the Height and Width at the same time.

Thank you.

I was able to successfully resize the chart using PowerPoint library from c#:

var presentation = PresentationDocument.Load("Chart.pptx");
var chart = ((GraphicFrame)presentation.Slides[0].Content.Drawings[0]).Chart;

chart.Frame.Layout.Width = Length.From(450.0, LengthUnit.Point);
chart.Frame.Layout.Height = Length.From(200.0, LengthUnit.Point);

presentation.Save("Resized Chart.pptx");

For more information you can refer to this example of PowerPoint charts in c#.
