In the Movement chart, you may see an option called Null Start with two choices:
Include
Not Include (default)
In general - this setting controls where the chart’s vertical axis begins.
What Is a “Null Start”?
Normally, charts begin the vertical axis (the y-axis) at zero.
A null start means the chart does not start at zero, but instead begins at the lowest value in your data.
This can make small differences between values appear larger on the chart.
Example (Simple)
If your data values are:
98
99
100
Not Include (default) → the y-axis starts at 0, and the variations look small.
Include → the y-axis starts at 98 (the lowest value), and the variations look larger.
Both are correct; they simply display the information differently.
When Should I Use “Null Start – Include”?
You may want to Include a null start if:
You want to highlight small changes or trends in your data.
Your values are all within a narrow range, and the default view makes everything look flat.
When Should I Use “Null Start – Not Include”?
The default Not Include is recommended when:
You want a neutral, easy-to-interpret view of your data.
You prefer the chart to start at zero for consistency.
You are comparing ranges and want to avoid exaggerating differences.
Most users should leave the setting at Not Include unless they have a specific reason to change it.
Does This Affect Your Data?
No.
Null Start only changes how the chart looks, not the actual data, totals, or calculations.
Summary
Setting | What It Does | Best For |
Not Include (default) | Y-axis starts at zero | Most situations; general accuracy and consistency |
Include | Y-axis starts at the lowest value found in your data | Highlighting small variations or trends |
