Chart.js line chart - Max on 100%

[bastienuh]

Hi all,

Sorry, but the slack link is not working anymore : https://chartjs-slack.herokuapp.com/ 😢
So I'm trying to ask here...

I'm looking to a feature, but I don't know if it exists with Chart.js on a plugin.

I have three datasets as following:

But I want that my highest point is considered as 100 and all the other points placed according to highest point. In fact, I'm trying to reproduce the Google Trends behavior, but I'm wondering is a plugin could compute datasets instead of making it myself.

Google Trend example:

Could anyone help me or give me some advice?

Thanks a lot!

Well wont expect that within 2 minutes, but afaik there is no plugin for this so you will just need to transform your own data beforehand by looking for the highest number and calculate the percentages from that and then pass that to chart.js

The problem of you solution is that I need to make this each time a dataset is hidden thanks to a click on the legend...
