Confidence Graph

First, I wanted to say I love this calculator. Its amazing truly.

One suggestion I have is to possibly show on the graph the confidence between the min and max values. So in my example below, it shows that for Tues PM the max value is 190 and min is 57 but there’s a 75% chance that the value is between 133 and 86. Showing that on the graph would be helpful.

Current Values
Previous Pattern: Small Spike
Purchase: 95
Mon AM: 107
Mon PM: 105
Tues AM: 128

I actually think that out of everything, a box plot would actually be the most ideal chart for this.

Not only does it fulfills @SvecTech 's criteria to be able to see the range in which half of the outcomes lie in, but it also fixes one of my annoyances with both the current line chart, and the ac-turnip.com calculator: they both depict turnip prices as a continuous function. Such is not the case—turnip prices only change twice a day, but the line graph subtly implies they constantly ebb and flow.

EDIT: Here is a chart.js module for box plots.

I don’t think a confidence graph is right because there are several functions to choose among. A trend flat across at 200 and one flat across at 50, eg, should show that there is very little in the middle.

A better view would have a kind of heatmap of the predicted values. Paint a swath across with some semitransparent color, so that they add up in force.

The danger is that uneducated readers will interpret darkest as the direction they’ll go, so please include a floating note, like “2% = 1 week out of 50, this will be you”.
