I saw the redraw function who is use in a code i work with and even if the documentation tell me that the function redraw the chart I don't understand what does that mean.
My point is what the interest to redraw the chart? Is that the function is redrawing the chart by reloading the store who are used by id? If I change my data and I redraw the chart, is that the chart is reloading using my new datas? Or Is that the redraw function is use to reset all of it and it just redraw the data?
