By default, the plot is displayed in Autoscale mode, where data is plotted over ranges to display all points of all datasets. For some plots, a primary dataset is defined in the framework and the axes' ranges calculated based on that dataset.
To access available tools, the Autoscale mode needs to be switched off.
