Notes

  1. The multiple Y axes graph is composed of multiple layers. Each Y axis is a separate layer.
  2. When the worksheet data selection includes a single X column, each Y column will be plotted to its own layer, by default.
  3. When the worksheet data selection includes multiple X columns, the number of layers will = equal the number of X columns, and each Y column will plot against the nearest X column to the left of the Y column, by default.
  4. By clearing the Auto boxes beside Number of Left Y Axes and Number of Right Y Axes, you can manually specify the number of left- and right-Y axes.
  5. By clearing the Auto box beside Number of Plots in Each Layer, you can enter a space-separated list of plots to add to each layer.
  6. Plots will be grouped within the layer and differentiated by any plot properties that were set to Increment when the graph template was saved.
  7. If you select Column as Plot Type, the option Column/Bar/Box Gap Across Layers will be checked by default.
  8. Multiple X axes will be linked to the X axis of Layer1 in a Straight(1 to 1) fashion. Y axes are not linked.
