This site lets you create a ternary plot quickly and easily! Don’t know what ternary plot is? No problem, just check the explanation page.
Some some sample data is loaded into the tables to show you it works. Try clicking all the “plot” buttons below for a quick example of a ternary plot. Check the 'How To Use' section below for all the details on how to plot points, lines, and areas. Happy ternary plotting!




How To Use

Input Parameters

The first row has to contain your column names. Your variable names have to be the first three values of this first row. These first three will be entered as axis labels in the ternary plot.
The axis labels are placed in counter-clockwise order: First column: top, second column: left, third column: right. Note that you have to keep the order of the your three column names consistent between points, lines and areas. You will get a warning when these are not consistent between the points, lines, and areas tables.

Other parameters, like color, opacity or shape also have to be named to in the top row. If you are confused, try reloading the page and taking a good look at the sample data!

For the values you can use either decimals 0.2, 0.3, 0.5 or percentages 20, 30, 50. Mixing these formats between rows is possible. You can't mix formats in one row though!

Also do not enter the percentage symbol (%)!

You have to enter three values for a point, line or area to be plotted, and the three can't sum to more than 100%.

Different lines and areas are seperated by one empty row. Only the first row of a a line or area style parameters area read. The optional parameters on following rows won't be read.

Save for next time

Your entered values are saved automatically locally in your browser storage. So when you come back to this page later, you'll be asked wether you want to reload these values.
