# Y Axis

Each plot in ngscopeclient has its own Y axis, shared by all waveforms within the plot. You can adjust the axis with the mouse:

  * Drag up and down to adjust DC offset
  * Scroll in and out to adjust gain
  * Middle-click to auto fit gain and offset to min/max of the current waveform

This will simultaneously control the frontend configuration for all physical instrument channels in the same plot, as well as adjusting the display position/scale of filters.

(If you need an exact scale/offset for some reason you can type values into the axis configuration in the channel properties dialog, but this is rarely needed.)

Try adjusting the vertical axis on one of the plots.
