How do I edit the range of x- and y-axis?

You can manually set the value of both of the x- and y-axis on both histograms and scatter plots. By default, the x- and y-axis range will be selected that is suitable for all viewed data. To manually set the range for either the x- or y-axis:

1. Go to 'This Chart' section.
2. Untick the 'Auto-Range' check box
3. Use the arrow keys or type in a new size value. (press Enter to accept new values if they are typed in this field). 

Set the y-axis value to zero

By default, a y-axis range will be selected so that it is suitable for all viewed data. To manually set the y-axis to zero: 

1. Go to 'This Chart' section.
2. Tick the ''Set Y-Axis Min to 0' check box.
