Conclusion
Although Excel's charting engine has a relatively poor reputation among users, most of that is due to a lack of knowledge about how to exploit the engine, rather than a lack of features. Yes, we would like to see significant improvements in the quality of the graphics, proper support for true 3D contour and XYZ scatter plots and a general overhaul of the user interface to make the advanced techniques shown in this chapter much more discoverable for the average user. However, after we've spent the time to explore the charting engine and fully understand the techniques introduced here, we realize that the limits of Excel's charting capabilities are to be found in our imagination and creativity, rather than with Excel.
