What does a waterfall plot show?
The waterfall plot is often used to show how two-dimensional information changes over time or some other variable such as rotational speed. The term waterfall plot is sometimes used as a synonym of spectrogram or cumulative spectral decay (CSD) plot.
What is a waterfall plot for vibration analysis?
Waterfalls, also referred to as cascade plots or spectral maps, consist of a series of spectrums placed one behind the other to generate a 3-dimensional graph. The X-axis represents Frequency, the Y-axis represents vibration amplitude and the Z-axis represents time or machine speed.
What does a waterfall graph look like?
Stepped sine measurements have a reduced set of controls and some additional perspective options that are only used for stepped sine data. Each slice in a stepped sine measurement waterfall shows the spectrum data for a test frequency.
How do you read a waterfall plot oncology?
Waterfall plots are an ordered histogram depicting the best percentage change in tumor size with positive values representing increase in size of tumor and negative values representing shrinkage of tumor. Each vertical column represents a single patient.
What is a waterfall response?
Waterfall plots are graphic illustrations of data that can vary from audio frequencies to clinical trial patient information and results. In oncology, for example, a waterfall plot may be used to present each individual patient’s response to a particular drug based on a parameter, such as tumor burden.
What is waterfall analysis?
Waterfall Analysis – Everything you need to know. A general ‘waterfall’ is an analytical tool that visually presents the sequential breakdown of a starting value (ex: revenue) to a final result (ex: profit) by displaying intermediate values and ‘leakage’ points. This can be used by companies to track data on each step.
How do you create a waterfall plot?
Create a waterfall chart

When would you use a waterfall plot?
Waterfall Charts are used to visually illustrate how a starting value of something (say, a beginning monthly balance in a checking account) becomes a final value (such as the balance in the account at the end of the month) through a series of intermediate additions (deposits, transfers in) and subtractions (checks …
What is a limitation of waterfall plots?
As stated previously, since each vertical plot represents a single patient, waterfall plots limit the ability to portray different randomization schemes, e.g., 2:1 or 3:1, in a manner that is readily illustrated and clearly comprehended.
How are waterfall plots used in cancer treatment?
Waterfall plots have gained in popularity as a means to visualize the change in tumor size for subjects in a study. The graph displays the reduction in tumor size in ascending order with the subjects with the most reduction on the right. Each subject is represented by a bar classified by the treatment.
Which is the best definition of a waterfall plot?
A waterfall plot is an ordered histogram where each patient is represented by a single vertical bar that can be further subgrouped by symbols or color for visualization.
Are there measurement error associated with waterfall plots?
There has been little recognition of measurement error associated with waterfall plots, despite every pair of measurements being subject to error ( 4–6 ). Bias may also occur if measurements are made with knowledge of prior treatment, generally in the direction of showing greater tumor shrinkage with new treatments.
What makes a graph look like a waterfall?
The length of each vertical bar hanging below the horizontal axis increases as the plot moves to the right side of the graph, thus resembling a waterfall and giving the graph its name.
