9.3 Managing data in plots

Changing the channel selection

When plotting a dataset, the graph will show the first channel of the list.

To change the plotted channel, complete the next step:

1. Click on the arrow next to the channel name at the top of the plot.
2. Select the desired channel from the drop-down menu.

or

1. Place your mouse on the channel name at the top of the plot.
2. Scroll with the mouse scroll wheel.

Changing the data block selection

Within the Analyze module, the title of the plot also displays which data blocks are being shown. Similar to the channel selection, this can be changed by clicking on the block name to access the drop-down menu, as shown on the right side of the previous figure, or by using the scrollbar. Typically, we desire to show the spectra for several blocks simultaneously by holding CTRL or SHIFT while selecting multiple blocks in the title.

Pinning channels in graphs

The selection title in graphs shows which datasets are available for the particular channel or block using filled or open circles. By clicking on the icon, you can “pin” the dataset, so the selection stays on that row/column when you change the selection of the whole graph. This is useful when multiple datasets are plotted in one graph that do not have matching block labels. An example is shown on the left side of the figure above.

Data averaging

By channel / row

If multiple channels are plotted on the same graph, you can set the type of averaging that is used to plot this data. By default, no averaging will be used. If you click on the channel name in the plot title, the type of averaging will be displayed below the channel list (set to All by default). The channel averaging can be changed to mean, maximum, etc. An interesting option is also Norm, which allows to easily show the vector norm of X, Y and Z directions of a single sensor.

By data block / column

Within the Analyze module, we also have the option to set the averaging that is used for viewing several data blocks. Similar to the channel averaging, one can set the data block averaging by clicking on the block name in the plot title, and selecting the type of averaging in the drop-down menu below the channel list, as shown on the right side of the figure. The block averaging can be changed to mean, maximum, etc.
