我已经使用epplus C#在图表内创建了一个文本框，但我无法将此文本框位置移出XAsix，请使用此代码---

var tb1 = Worksheet4.Drawings.AddShape("tb1", eShapeStyle.Rect);
tb1.Text = "‘ASSUMES $100 INVESTED ON SEP. 30, 2017" + Environment.NewLine + " ASSUMES DIVIDEND REINVESTED" + Environment.NewLine +"FISCAL YEAR ENDING SEP. 30, 2022’";
tb1.SetPosition(32, 0, 5, 0);
tb1.SetSize(300, 100);
string fontColor = "#808080";
tb1.Font.Color = fontColor.ConvertToColor();
tb1.Font.SetFromFont("Calibri", 9, true, false, false, false);

tb1.TextAlignment = eTextAlignment.Center;
tb1.Fill.Color = Color.White;
tb1.Border.Width = 0;
