## Frequently Asked Questions
220
+
221
+
**Q: Does adding a TextBox affect chart performance?**
222
+
A: The impact is minimal; however, for very large workbooks, limit the number of shape objects to keep memory usage low.
223
+
224
+
**Q: Can I position the TextBox using cell references instead of pixels?**
225
+
A: Yes, you can calculate pixel coordinates from cell indices or use the `addTextBox` method on a worksheet for cell‑based positioning.
226
+
227
+
**Q: Is there a way to bind the TextBox text to a cell value?**
228
+
A: Aspose.Cells does not provide direct data binding for shapes, but you can programmatically update the TextBox text after reading a cell’s value.
229
+
230
+
**Q: What licenses are required for commercial deployment?**
231
+
A: A purchased Aspose.Cells license removes all evaluation restrictions and is required for production use.
232
+
233
+
**Q: Where can I find more examples of chart manipulation?**
234
+
A: The official Aspose.Cells documentation and sample repository contain many scenarios, including dynamic series, chart types, and styling.
