May 2017: For our American friends, we have just added a CDC chart option to the plotters for older children aged 2-20y. For infants and toddlers aged 0-2y, CDC now recommends health care providers use these WHO growth standards to monitor growth.
This page is running on a Shiny server that allows the statistical package R to plot growth on the 2014 WHO Growth Charts for Canada, published by the Public Health Agency of Canada for ages 0-2 years. Set 1 and 2 charts differ only in the selection of percentiles in the normal range, with Set 2 being more granular.
A spreadsheet with comma separated variables (.csv) can be created using the 'Save As' .csv option in Excel and uploaded using the sidebar on the left. Column names must be as shown in the sample .csv file below, but column order is immaterial and additional columns are simply ignored. The variable agemons is age in months; weight is in kg; and length/head circumference (hc) are in cm.
You can of course use date variables to calculate agemons in your spreadsheet. Excel typically returns the differences between two dates in days, and I use the recommended WHO conversion of 30.4375 days per month to convert to age in months. For assistance, please see our illustrated guide: Creating .csv spreadsheets
Once you've uploaded a dataset and selected your plot options, you must click the
button to render your plot.If you have not yet uploaded a .csv file, the sample data will be displayed by the plot buttons. If you need to calculate Z scores using the WHO 2013
, your spreadsheet can also be uploaded to the Z-score calculators listed in the sidebar. The low resolution thumbnail images are rendered at 72 dpi. Right-click (control-click) to copy or save them. To download hi-resolution images for presentation or publication, just click the download button
