Column chart                Table Interface

Histogram / Table Interface:

Histogram:

The capacity and power are expressed in two colors, the unit is as follows, the measurement length is 65 units, and the calculation formula is as follows

Capacity:

Red: x, unit: 200mAh;

Yellow: y, unit: 2000/65=30.76mAh;

Capacity: =2000*x + 3.07 * y(Wh)

Electricity:

Blue: x, unit: 200Wh;

Green: y, unit: 200/65 = 3.07Wh

Electricity = 200 * x + 3.07 * y (Wh)

Form interface:

The data of each group can be directly compared according to the data value;

Functional description of this interface:

1. Click K1: up data clear window. Press K1/K2 to clear the current selected group data to 0/cancel.

2. Click K2: Switch group;

3. Long press K2: Histogram/table interface switch;

4. Long press K1: return to the capacity/power record interface
