Hi, i must draw more than 2 series on a chart, each one have their min/max (for example, T1° [-20;80], T2°[20;60], ...) To avoid a shrink of the graph with a lot of vertical axis, i would like to draw only one Y axis : 0-100%. In this case, for the serie T° for example -20°=0% and 80°=100% (etc...)....
