Hoping someone can help me figure out how to fix the X:Y plotting ratio on a chart.
For example, if I wanted to find the slope or angle formed by the line drawn through the Last Close to the Close of Five Bars Ago, that slope or angle would be very different if I was zoomed into the chart or zoomed out.
How can I fix the Y scale against the X scale of a chart in my AFL and make it exact, for the purpose of calculating these angles? I checked the Users Guide and don't see any obvious parameter or option I can set.
Right now, this is what I have at the top of my AFL to plot the chart:
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) Vol " +WriteVal( V, 1.0 ) +" {VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 )) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleThick | ParamStyle("Style") | GetPriceStyle() );
