Combine nodes with Merge Merge lets you combine nodes of a single category, or edges of a single relationship based on a property value. This is useful for simplifying a graph quickly. In our example data we can use the seasonEpisode property in the Lines category to combine all of the lines spoken on a single episode into a single Lines node connected to its Episodes node. Examples use the open-source dataset for the HBO Game of Thrones series. For a hands-on exercise see our How to GraphXR tutorials. To combine nodes using Merge: Deselect all the data to operate on all the data. Open the Transform panel and Merge subpanel. In Choose merge type, click Category and select the Lines category from the dropdown menu. In the Select Property dropdown menu, select the seasonEpisode property. In Options, click the Clear Unselected Properties checkbox. A merged node will preserve only one of the values for each property from its source nodes. The preserved property value on a merged node is usually meaningless and should be cleared. Click the Run button, which also indicates how many nodes (or edges) will be included in the merge. The Log beneath the Run button displays error and status messages. On the canvas, the merged graph is now far simpler. Instead of a few thousand nodes, the Lines category now includes only 73 nodes, the number of episodes in the series.
