Sorry, we can't see the image of a 3D chart you refer to. You can send it as an attachment to support@quinn-curtis.com if you want and we will take a look at it.
The example program Bargraphs.SimpleBars draws uses all three axes. In that example the z-axis uses string labels, though they could just as easily be numeric labels as done for the other axes. The example program Bargraphs.Barplot3D uses a SimpleDataset3D to store 3D data points and plot the points as bars in the chart.
The example program SimpleLinePlots.LinePlot3D uses and displays all three axes.
Sorry, but the jpeg images you sent were too low resolution for us to determine what plot types might be appropriate. Send higher quality images or a program that can recreate the images in high resolution.
