Getting Started with Editing

In the main page, select the Manage card. Navigate to Traces page. Select the trace to be edited. In the RANDOM FACTOR column, click on Add, then Random Factor.

The way the graph works is that given a random point on the x axis, the corrsponding y coordination is the calculation result.

Graph Samples

Random factor x is more likely to approach 0 or 1

Random factor x is more likely to approach 0.5

In Adding salt popover, choose the demanded transform from rotate, scale and translate.

Rotation

Select Rotation from the Adding salt popover. Expand this transform. Click on the Σ button on the right, then click Use input. Type the following text in the radian input.

2 * pi * x

Reasoning

In radian, 2π is one circumference. x ranges in [0, 1]. This random transform rotates the trace around at most.

Translation

Select Translation from the Adding salt popover. Expand this transform. Type the following text in both the x and y inputs.

x * 10 ^ -4

不知道是啥语言

Reasoning

^ stands for exponential operation, 10 ^ -4 is ten to the power of minus four. This random transform translates the trace for ten to the power of minus four in the latitude direction.

Rotation

Choose Scale from the Adding salt popover. Expand this transform. Type the following text in the x ratio input.

e ^ -x

不知道是啥语言

Reasoning

e is the base of the natural logarithm. This is just for fun.
