setLineWidth method
set the line width of the chart (min = 0.2f, max = 12f); default 2f NOTE: thinner line == better performance, thicker line == worse performance
@param width
Implementation
void setLineWidth(double width) {
if (width < 0.2) width = 0.2;
if (width > 12.0) width = 12.0;
_lineWidth = Utils.convertDpToPixel(width);
}
