Common Graph Operations

This section describes functions that are common to panes that display graphs, such as Spectrum, Timechart, and Calibration Curve.

Adjusting the scales

The scales for the X- and Y-axes of the graph are optimized by default.

To adjust a scale, follow these steps:

  1. Move the cursor to the X or Y-axis.

    The cursor changes shape to image062.jpg (for the X-axis) or image064.jpg (for the Y-axis).

  2. Right-click and drag the mouse.

    The scale for the axis changes.

 

You can change the Y-axis scale in the Spectrum, Timechart, and Chromatogram (optional) panes by selecting a value out of the scale dropdown list.

The scroll wheel button returns to the default scale when clicked.

 

Shifting the axes

The X- and Y-axes of the graph can be transposed.

  1. Move the cursor towards the X or Y axis.

    The cursor changes shape to image06200120.jpg (for the X-axis) or image06400121.jpg (for the Y-axis).

  2. Left-click and drag the mouse.

    The axis shifts.
