Range on y-axis does not change when changing input parameters

Reading all refC2 models and plotting them for spring everything looks good. Change so that only median and mean are visible. Then change the filter so that autumn and spring are shown. Then change the filter to see the NH polar region. There is not plot anymore... or the values on the y-axis don't get automatically adjusted. I would expect that the y-axis adjusts automatically even when the model data is hidden.
