How to increase the length of history plotted by smoothie.js?

[Steven R]

I am using Django Channels to push updates to a smoothe.js chart once every second. 

My problem is that the chart does not retain a history longer than 30 seconds. What can I do to get smoothie.js to plot more data and retain a longer history?

Hi,

you can increase the millisPerPixel parameter to incresae your history.

e.g.:

var smoothie = new SmoothieChart({
                millisPerPixel: 1000,
            });
