Abstract: An information display method includes: obtaining a predicted property value of each of compounds; obtaining first display method information indicating a display method for the predicted property value; generating a map indicating the predicted property value of each of the compounds, according to the first display method information; and generating an image including the map, and outputting the image. The map includes a coordinate axis indicating each of at least two variables among variables to be used in representing compositions of the compounds.

Abstract: An information display method including: obtaining first information for displaying an evaluated property value as a comparison indicator for comparing compounds; obtaining an evaluated property value of each of the compounds based on the first information, and generating a map indicating, at a position corresponding to a composition of each of the compounds, the evaluated property value of the compound; generating a first image including the map, and outputting the first image to a displayer; and when the first information is changed, changing the map according to the first information changed, generating a second image including the map changed, and outputting the second image to the displayer.

Abstract: A hydraulic system for a work machine includes a first switch valve and a first return circuit. The first switch valve is switchable between a confluent position and an isolation position. The first switch valve is switched to the confluent position such that a first operation fluid tube is connected to a second operation fluid tube and a first transmission fluid tube is connected to a second transmission fluid tube. The first switch valve is switched to the isolation position such that the first operation fluid tube is disconnected from the second operation fluid tube and the first operation fluid tube is disconnected from the second operation fluid tube.
