Overlay

Overlay is possible in all types of plots except Surface Plot.

3D Scatter Plot

To overlay 3D plots (simultaneously viewing multiple plots with similar range on the same axes system)

1. Select column to be plotted on the X-axis.
2. Select column to be plotted on the Y-axis.
3. Select column to be plotted on the Z-axis.
4. Click on ``3D Scatter Plot'' icon of the toolbar.
5. Select column to be plotted on X-axis (represents another plot).
6. Select column to be plotted on Y-axis (represents another plot).
7. Select column to be plotted on Z-axis (represents another plot) .
8. Set the "Overlay" option.
9. Click on ``3D Scatter Plot'' icon of the toolbar.

A different marker will be used for each plot, to allow one to differentiate between the plots.

Example of overlayed 3D Scatter Plot is shown in Figure 6.

3D Histogram

To overlay histograms (simultaneously viewing multiple histograms with similar range)

1. Select column to be plotted on the X-axis.
2. Select column to be plotted on the Z-axis.
3. Click on ``3D Histogram'' icon of the toolbar.
4. Select column to be plotted on X-axis (represents another plot).
5. Select column to be plotted on Z-axis (represents another plot).
6. Set the "Overlay" option.
7. Click on ``3D Histogram'' icon of the toolbar.

A different color will be used for each histogram, to allow one to differentiate between the histograms.

Example of overlayed 3D histogram is shown in Figure 7.
