Algorithm to Create Correct Multiple Axes Chart
[Category : - SOFTWARES]
[Viewed 1470 times]
The key to present the correct information on a line chart is the setting of the scales of its vertical axis, including the lower limit, upper limit, and interval scale. For example, on a single vertical axis line chart, changing its lower limit and upper limit from “0” and “10” to “0” and “1,000” makes the displayed line become so flat as there has been no movement for such dataset and thus misleads the reader.
This scaling problem has been the reason that multiple axes chart cannot present the correct relation or comparison of multiple datasets and has been questioned for decades, while it has still been broadly used when people visualize datasets with different unit in their respective original unit, such as comparing “the unit sold and the average selling price“ or “stock traded in USD and in RMB”. The patented algorithm however, through defining and equalizing the elongation of every vertical axis on a multiple axes chart, solves the problem. With all the vertical axes at the same elongation, the chart can correctly show which dataset increase/varies more or less during the period.
The algorithm can be easily adopted on any chart creating software such as Excel, Bloomberg, or any Business Intelligence software
COMPETITIVE ADVANTAGE
Multiple axes chart is commonly used in data analysis and software, especially when comparing datasets with different units, to present the relation between multiple datasets in their original values, such as which dataset has increased more or less.
However, due to lack of an algorithm which can set the top scale and the bottom scale of the multiple vertical axes on such chart, many software today simply use the maximum value and minimum value of each dataset as the top scale and bottom scale of each vertical axes. The result is that all the lines are incorrectly presented as fluctuated greatly and fluctuated the same.
The only way to present the correct relation between multiple datasets is to equalize the elongation of all the compared vertical axes, which none of the software today can do. By incorporating our scaling algorithm, chart creating software can produce correctly multiple vertical axes chart for multiple datasets comparison.
Financial information
We focus on algorithm development and patent licensing. We have 5 patents which are related to algorithm for visualization of data and we are now seeking to license or sell.
Many of our patents or applications solve several algorithm problems that have been existed for 30 years in the field of chart creating, and we can see the commercialized value of them if combined with the suitable platform or software.
