29.6.11 Multiple Y Axes Graph

MultiY-Graph

Data Requirements

Requires a selection of Y column(s) (or a range from Y columns). If there is an associated X column, X column supplies X values; otherwise, sampling interval of the Y column or row number is used.

Creating the Graph

Select the required data.

Select Plot > Multi-Panel/Axis: Multiple Y Axes....

or

Click the Multiple Y Axes... button on the 2D Graphs toolbar.

Origin opens the plotmyaxes dialog box.

Customize the graphing options, including the plot type of each plot in the layer, the number of Y axes to the left, right, or in the middle of the graph and the display of the Y titles and the top X axis, etc. See details here

Template

OffsetY.OTP (installed to the Origin program folder).

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.
